The purpose of this document is to take the user through some of the steps required to set up the program and get to the stage where they can create a plan and survey.
This document assumes that Well Seeker Pro has already been installed (see Manual for Install guide) and this is the first time the program has been opened.
When you first open Well Seeker, the screen will be configured as below.
The layout of the screen can be adjusted by going to View - Toolbars and Docking Windows:
The user can then choose what to display. For the rest of this document, the Output and Properties windows will be unselected.
The database is the .mdb file that Well Seeker Pro is directed to access information from. It is vitally important that the user is aware of the location of and backs up their database file regularly to another storage device. If this is done correctly then the user will always have a backup in the event of an unforeseen event such as a computer hard drive failure, that would have otherwise resulted in the loss of the database file and all the input data. The database can be quickly backed up by going to File > Backup Database.
The first thing to do when creating a new database is to select where you want to store the database on your computer. Ideally you want to put it somewhere where it will not need to be moved.
Create a folder somewhere in the C: drive and name it appropriately.
Go to File > Create New Database.
The box below will appear.
Navigate to the desired location where you will save the new database and enter your database name in the File Name: box and click Save.
The new database will now have been created as a .mdb file at your chosen destination.
Go to File > Select Database, browse to and select the database you have just created.
You have now created a new database and your screen should look like above, note that the database you have selected will be displayed at the bottom of the screen as highlighted by the red box.
You can navigate to the file location of your database by opening the Help menu and selecting Open database location. To backup your database file open the File menu and select Backup Database. This will open a dialog box where you can choose a suitable location and name for the backup.
It is very straightforward to switch between databases, making it easy to maintain multiple databases depending on the user's needs.
Go to File - Select Database.
Go to the location of the database you would like to use.
Select the database and hit open.
The new database will now be selected and can be used.
The following section details the steps to follow in order to create a new well.
The first thing to do is to make sure that you have the correct units selected.
Click on the Units icon located in the bar at the top of the screen or open the Tools menu and select Unit Sets.
This will open the Unit Sets dialog box
Well Seeker comes as standard with 5 unit sets (API, CAD, ND, SI & US), which are all editable.
There is also the option to create a new unit set using the Create new button. To edit a new unit set, click the Edit button. This will allow the user to access the unit drop down menus to change the parameters to the desired units.
Depth: Current units for measured depth and TVD. Options are Feet, US Feet and Meters.
Local: Current units for NS, EW and centre to centre distances. Options are Feet, US Feet and Meters.
Geographic: Defines what units the map co-ordinates are displayed in. Options are CRS Default (the unit set defined by the selected CRS), Feet, US Feet and Meters.
Diameter: This defines the units used to display Casing OD and ID as well as hole size. Options are mm and inches.
Dogleg: The current units DLS, BR and TR are displayed in. Options are Deg/100ft (or 30m), Deg/30ft (or 10m) or user defined. If user defined is selected, the parameter column becomes active and the units value becomes degrees per unit length based on the parameter entered.
Survey Calculation Method: This defines which calculation method is used for calculating survey parameters throughout Well Seeker PRO. Options are Minimum Curvature, Radius of Curvature, Tangential and Balanced Tangential. It should be noted that if a method other than minimum curvature is selected the Well Planning tools will not work.
Flow Rate: Current units for flow rate. User can choose between LPM and GPM.
Pressure: Current units for Pressure. User can choose between Bar and psi
Volume: Current units for Volume. User can choose between BBLS and m3
Mud: Current units for Mud Weight. User can choose between PPG, SG, psi/ft3 and lbs/ft3
Weight: Current units for Weight. User can choose between klbs and Tons
Torque: Current units for Torque. User can choose between kftlb and kNm
Temperature: Current units for Temperature. User can choose between degC and degF.
Cost: Current units for Cost. User can choose between $, EUR and GBP.
Jets: Current units for Jet size. User can choose between in2 and mm2.
Whatever is selected here will be applied to the whole database. It can be changed at any point, but the units are set for the whole database and not individual operators or wells.
Special care must be taken at this point because the survey calculation method affects the way the plans and surveys are generated. It is very unlikely that anything other than Minimum Curvature will ever be selected.
It is possible to create an instant plan or survey in Well Seeker. This can allow the user quick access to the planning tools without having to go through the process of filling in all the different levels of data to get there. For this kind of requirement, surface locations, elevations etc are of no concern and Well Seeker uses generic values at all the levels.
To create an instant plan or survey, right click on the database and select New Instant Plan or New Instant Survey.
Right click on the database and select Insert New Operator.
The Operator Properties box will now appear.
The Operator level is where the user sets up the company anti-collision policy, and it is very important to ensure this is done correctly.
This is also the level where the primary and secondary logos are added. These logos are then available to be included on generated reports.
Right click on the Operator and select Insert New Field.
The Field Properties box will now appear.
The following data is input at this level:
Mapping Grid or Coordinate Reference System (CRS). If the required CRS is not available a new one can be added (see the Adding a New Coordinate Reference System section).
Azimuth North Reference: Grid or True.
Local Coordinate system:
Well Centred - Local coordinates for all plans & surveys will be referenced to the well location making all local coordinates 0.00N & 0.00E at surface.
Facility Centred - Local coordinates for all plans & Surveys will be referenced to the facility location meaning local coordinates at surface will vary between wells.
Apply Scale Factor: If this option is selected, the scale factor defined in the CRS will be used to calculate map co-ordinates from local co-ordinates. This is the ratio between measured distances on the map compared to measured distances on the ground as a result of distortion of linear scale associated with mapping a spherical surface (the earth) onto a plane. Note that this option does not affect the local coordinates, only the map coordinates (Northing and Easting’s).
Show Map: This extends the existing dialog to include a Google Maps section. This will show the location of the positional data entered and can be toggled between map and satellite view using the Satellite checkbox. The map can also be zoomed in and out using the – and + buttons. This map location will only be accurate if the CRS selected uses WGS 84, as this is what Google Maps utilises.
Show Field Ref Point on Report: When selected, the field reference point coordinates will be included in the Field data box of any report generated. Default is off.
Field Reference Point: This is the reference location used for the field.
Input: Select the coordinates used to enter the Field Reference Point. Either Latitude & Longitude or Grid Easting & Northing.
Grid Convergence is not editable as it is based on the CRS selected and the Field Reference Point entered.
System Vertical Datum: This is the datum which all TVDs below field level will be referenced to. This is usually either mean sea level “MSL”, lowest astronomical tide “LAT” or some other user specified value. If a value other than MSL is selected from the combo box, the elevation above or below MSL must be entered. A positive value indicates that the datum is above mean sea level and a negative value indicates it is below it.
Once the required inputs have been completed, click Apply then Close on the bottom right of the window. To access the Field Properties again at any time, right click at the Field level and select properties
Right click on the Field and select Insert New Facility
The Facility Properties box will now appear
The following data is input at this level:
A slot template can be created by Clicking on the Templates button (see Creating a Slot Template section for more detailed instructions)
Lease /Hard Lines: The user can select to have lease / hard lines show at all levels within the Targets dialog. On will pre-select the lease / hard lines to be displayed from Field to Actual / Plan levels. Off will pre-select the lease / hard lines to be displayed from Field to Facility level only.
Show Map: This extends the existing dialog to include a Google Maps section. This will show the location of the positional data entered and can be toggled between map and satellite view using the Satellite checkbox. The map can also be zoomed in and out using the – and + buttons. This map location will only be accurate if the CRS selected uses WGS 84, as this is what Google Maps utilises.
Facility Reference Point: This is the reference location used for the facility. For an offshore platform, this is usually platform centre and for an onshore facility, this is usually the centre of the site. This location will provide the Local Coordinates of 0.00N & 0.00E if Facility Centred Local Coordinate System was selected in the level above
Input: Facility Reference Point Select the units used to enter the Facility Reference Point. Either Latitude & Longitude or Grid Easting & Northing.
Grid Convergence is not editable as it is based on the CRS selected and the Facility Reference Point entered.
Facility Location Uncertainty: The uncertainty of the facility location to 1 sigma. If unknown, leave as 0.
Once the required inputs have been completed, click Apply then Close on the bottom right of the window. To access the Facility Properties again at any time, right click at the Facility level and select properties.
Right click on the Facility and select Insert New Well
The Well Properties box will now appear
The following data is input at this level:
Location Uncertainty: The uncertainty of the Wellhead location to 1 sigma. If unknown, leave as 0.
Wellhead Location:
Slot: This allows the user to select any of the slots created in the template editor and the location will be automatically input based on this selection
Offset from Facility: This is the local Coordinates which allows the user to enter the distances at surface between the facility location and the wellhead location
Map: Input location as Grid Easting & Northing
Geographic: Input location as Latitude & Longitude
Depth Reference: Allows the user to input the relevant elevations. Default is for an onshore well with Ground Level to MSL, however If “offshore” is selected, the user can enter the well head elevation above MSL. If “subsea” is selected, the elevation below MSL can be entered. This is the distance between the top of the well head and MSL. By checking the Default box, the selected elevation will be automatically assigned to any new plans or surveys created.
Show Map: This extends the existing dialog to include a Google Maps section. This will show the location of the positional data entered and can be toggled between map and satellite view using the Satellite checkbox. The map can also be zoomed in and out using the – and + buttons. This map location will only be accurate if the CRS selected uses WGS 84, as this is what Google Maps utilises.
Once the required inputs have been completed, click Apply then Close on the bottom right of the window. To access the Well Properties again at any time, right click at the well level and select properties.
Right click on the Well and select Insert Planned Well
The Plan Properties box will now appear
The following data is input at this level:
Set as Principal Plan: Selecting a plan as the principal sets it apart from the other plans as the most important one, and it also tells Well Seeker to use it as the reference plan when the user is in a survey file under the same well. When inputting surveys, Well Seeker will display details telling the user how far away, Toolface, X & Y offset etc the survey is from the principal plan.
Tolerance Circles: Tolerance circles are for visual reference only. The radius of the inner and outer tolerance circles can be added here. These can be displayed in a plan or spider plot by selecting their inclusion in the chart properties dialog. The default colours for the inner and outer tolerance circles can be adjust in the Plots>Chart Defaults menu.
Survey Tools: The Survey tool editor can be accessed from here by clicking on the Survey Tools button located beside the Apply button.
Vertical Section: The VS azimuth and the local origin of the VS.
Depth Reference: This will be the selected default (from Well Level), but can be changed by selecting options from the drop down list.
Magnetics: Magnetic data can be generated here by selecting the model and the date. If the relevant model is not available, user defined details can be added. Several lines can be added to the magnetics table; however, only the data which is checked as Active will be used by the program.
Survey Program: This is where you create the survey program and assign the relevant error models to the plan. At this stage, because there is no plan yet this will remain incomplete (to be completed once a plan has been created). Error model can be assigned at this point by selecting from the drop down menu below IPM. However, if the plan is a sidetrack, then the details of the survey program from surface to ST depth can be entered. This will be done automatically when completing the Sidetrack details section.
Sidetrack Details: If plan is a ST, check the Plan is a sidetrack box and the user will be able to select the plan or survey that will act as the motherbore as well as determining the ST depth. By then selecting Create Sidetrack, the Survey program will be populated with the relevant details from the motherbore.
Tie-on: Allows the user to select where the plan is tied on. This can be from surface, a user defined point where the tie-on line can be manually typed in by the user or from an existing survey or a plan. This will be automatically populated when the Sidetrack Details section is completed.
Export Geomag Data: Exports the geomagnetics data as a document. Select the line in the Magnetics section that you want to export the geomagnetics data for. Then select the report format as PDF or Excel from the drop down menu, before selecting Export to generate the report.
Force Colour: Selecting this option and choosing a colour will ensure that this plan will always be displayed in this colour in all of the plots. This supersedes any colour options for this plan in the Chart Properties dialog.
Once the required inputs have been completed, hit apply then close
To access the Plan Properties again at any time, right click at the Plan level and select properties
The database tree should now look similar to the one below. In order to open the plan, the user must double click the Plan level of the database tree, and the plan window will open in the right hand screen. The plan can then be entered manually using MD, Inc and Azi, or the Planning Tools at the bottom of the screen. Once a plan has been created click Save. For more details on the Planning Tools, see Appendix A.
When you hit save for the first time, and again any time the plan is changed, the user is asked "Do you wish to add this plan to survey program". Select Yes. This will automatically update the survey program.
To check & edit the survey program, or assign an error model, open the Plan Properties. Left clicking on the Plan/survey column will reveal a drop-down menu with the available options. An appropriate error model can be selected from the drop-down list in the IPM column.
Click Apply and then close to save this selection.
To view the plan listed every 30m (100ft), double click on the Planned Wellbore level of the database tree and it will open this in the right-hand window.
When you have a plan selected, it is possible to choose what data you would like to be displayed by going to:
View - Show / Hide Columns
The user can choose which columns to be displayed. It is worth noting that the following columns will only be displayed for a survey (not a plan) even though they are selected, and will only be populated if one of the plans is selected as Principal:
Distance to Plan
TFO+Azi
TFO Highside
TC X&TC Y.
Up Down & Left Right
Closure Azimuth - can always be displayed in a survey regardless of whether there is a principal plan selected. It will not display in a plan.
The Targets properties box can be accessed from field level down by right clicking on the required level (Field, Facility, Well, Plan or Actual Well) and selecting Targets.
Select Create New and the Target Properties section will become editable.
Target shape, size and orientation can be selected by clicking on the desired tab at the centre right of the screen as seen highlighted by the red box in the above image.
If supplied with an azimuth and a horizontal displacement, target coordinates can be calculated by adding these values and selecting calculate. All target centre coordinates will be populated.
Drillers target can be calculated by selecting the desired confidence level (95% is the default) and selecting Create Drillers Target:
You will then be prompted to select the relevant plan before the calculation is done.
If the planned well path does not pass through the target, the calculation will not be carried out.
The size of the drillers target is affected by the Survey tool which is assigned to the plan - The more accurate the tool, the larger the drillers target.
The level that a target is created on will be displayed in the filter section. A target created at the Field level will only be seen at that level. A target created at plan level can be seen at all levels.
To see a target created at field level at plan level:
Open the target properties box at plan level - you will not be able to see the target.
Click on the Filter drop down menu and select Field.
You will now be able to choose which levels the target will be visible on. Just check the required box and click Save.
Lease lines and hard lines can be created by adding a target and selecting Polygon. The lease / hard line coordinates can then be entered in the same way as a polygon target. Once complete, the user should check the “Is a Lease Line” or “Is a Hard Line” box.
It is important to understand that once this has been checked, Well Seeker will see this as a lease line and not a target. The next time the user opens the target box, the lease / hard line will no longer be visible. To see the lease / hard lines, the user can select the “Show Lease Lines” option below the filter. This filter will hide the targets and display only the lease lines.
NOTE: Both targets and lease / hard lines will be available to plot and can be manipulated in a similar way in the chart properties dialog in the plots.
Casings can only be added at Actual Well and Plan level:
Right click on either and select Casing, and the casing details will appear.
The user can now fill in the required information.
Lithology details can only be added at Actual Well and Plan level:
Right click on either and select Lithologies, and the Lithologies box will appear.
The user can now fill in the required information.
Annotations can only be added at Actual Well and Plan level:
Right click on either and select Annotations, and the Annotations details will appear.
The user can now fill in the required information.
Right click on the Well and select Insert new actual well.
The Actual Wellbore Properties box will now appear.
The initial set up of the Actual Wellbore is the same as for a plan. Refer to Creating a New Well Plan Section.
Once the required inputs have been completed, click Apply then Close.
To access the Actual wellbore Properties again at any time, right click at the Actual Well level and select properties.
Right click on the Actual Well and select Insert new survey
The Survey Properties box will now appear
The user can select the appropriate Survey tool and select a tie-on.
Once the required inputs have been completed, click Apply then Close.
To access the Survey Properties again at any time, right click on the survey and select properties.
To enter the survey and add survey stations, double click on the survey you wish to add to, and the survey will open in the right-hand window.
A prompt will appear which asks, "Do you wish to add this survey to the survey program?". Select Yes.
Once a survey has been created and saved, the next step is to go back to the Actual Wellbore Properties and check the Survey program. Clicking on the Survey column will reveal a drop down menu with the available options. Any surveys which have been created below the Actual Wellbore will be available to select. Since a survey tool has already been assigned to each individual survey the IPM column will be automatically populated.
Click Apply and then Close to save this selection.
Once a survey has been added to the survey program, if new survey stations are added to the survey, on saving, Well Seeker will again prompt the user Do you wish to add new surveys to the survey program? Selecting yes will update the survey program Depth To column to include the latest surveys.
The Actual Wellbore is where the user can view the survey program listing.
Double clicking on the Actual Wellbore displays an un-editable listing which contains all the surveys assigned to the survey program
It is possible to import a Compass .xml file into Well Seeker. This file is an export file from Compass which contains details of plans, surveys, targets, error models etc. When this file is imported, all the information will be used to create the relevant wells within Well Seeker.
To import a Compass .xml file, select File > Import Compass EDM File. This will then open a screen which will allow the user to navigate to the relevant file and select it.
Once selected, Well Seeker will begin the import process. The time taken for this process will vary based on the size of the import.
Compass Import Settings: This option opens the compass import settings dialog, where the user can select the appropriate settings they desire when importing data from a Compass EDM file.
Targets and Lease Lines: Allows the user to either include or omit targets and lease lines when importing. The user can also choose if imported lease lines are automatically assigned to their appropriate wells.
Surveys Tools: When checked, Well Seeker will import any survey tools associated with the relevant plans and surveys. If unchecked no survey tools will be imported. Note, that if survey tools are not imported, and any of the imported plans and surveys reference a survey tool which is not available on the imported computer, then Well Seeker will use the default error model selected by the user.
Naming Conventions: Gives the user 3 options relating to the way Well Seeker names the imported data in the database tree. If all boxes in this section are unchecked, the data will just be pulled in as it is in the Compass export file.
Note: Well Seeker requires all items in the database tree (except for surveys) to have unique names, whilst Compass does not. Importing two items from Compass with the same name will cause a conflict in Well Seeker. For this reason, Innova recommend that these Naming Conventions should be turned on by default.
Append Operator Name to Field: Adds the relevant Operator name to the end of every Field name in the database.
Append Field Name to Facility: Adds the relevant Field name to the end of every Facility name in the database.
Append Facility Name to Well: Adds the relevant Facility name to the end of every Well name in the database.
Well Plans: This option allows the user to import ALL plans which are contained within a Compass Export file. If this option is not selected, then Well Seeker will only pull in the plans which are selected as PRINCIPAL in the export file. Default is ON.
At Facility level, it is possible to add a slot template. When in the Facility Properties window, select Templates, and the Template Editor window will pop up.
Properties: Select Create New to create a new template:
Select Template: This will populate automatically once the Name box has been completed and the template has been saved.
Name: Add the relevant name.
Slot Prefix: This will appear in front of all slot names.
Template Centre Relative to facility: This is only available when Rectangle or Circle is selected in Geometry. Allows the user to offset the centre of the template relative to the facility location entered in the Facility Properties window.
Geometry: Select from Rectangle, Circle or Single Slot. Single slot allows the user to create a slot template that is not a predefined shape and is made up of individually entered slots.
Rectangle: Contains available options related to the Rectangle Geometry and will only be editable when the Rectangle option is selected.
Circle: Contains available options related to the Circle Geometry and will only be editable when the Circle option is selected.
Convert to Single Slots: This option allows the user to convert rectangle and circle templates into single slots. This action is not reversible once it is selected.
Display slot names: Displays the names of the slots on the plan view on the right.
Slots: This is where the slot Name and local coordinates are input. The local coordinates are generated automatically for the Rectangle and Circle Geometry and are fully editable for the Single Slot option.
When a slot template has been created select apply to save
When more than one template has been created, the relevant template can be selected from the Select Template drop down menu at the top of the screen.
You may find yourself in a situation where you are required to do planning referencing a CRS which is not available in Well Seeker. In this situation the information relating to the CRS should be requested from the client and can then be used to create a new CRS in Well Seeker.
The below screen shot is an example of the type of information which will be supplied by the client.
The following instructions detail how to use this information to create a new CRS.
Open the Geomagnetic Calculator by clicking on the icon on the toolbar or go Tools > Geomag Calculator.
Click on the "Mapping Grid" button at the top left of the box.
Select Add CRS at the bottom left of the Mapping Grid.
You will now have a blank template which you can start adding information to.
Parameters in RED below are important and affect the output - Care should be taken to enter the data correctly
Name: This can be anything you want as it has no impact on any of the calculations. In Well Seeker, the naming convention is the System / and then the Map Projection, and it is recommended that this convention is followed. For this example, the name would therefore be Polska 1992 / Transverse Mercator (Gauss-Kruger) Zone 3
Area of use: Description of which part of the earth this CRS references and has no effect on any of the calculations. For this example all we know is it is in Poland.
Datum: This is just text and does not directly affect any calculations. For this example it is WGS1984.
System: This is just text and does not directly affect any calculations. Polska 1992
Ellipsoid: This is an important one and you have to choose from a drop down list of 38 options. In this example you would choose WGS 84
Semi Major Axis (m): This is the Equatorial Radius of the Ellipsoid and is automatically populated based on the ellipsoid selected.
Semi Major Axis (UOM): This is the equatorial radius of the ellipsoid in the units of measure which the CRS is using and is automatically populated based on the ellipsoid selected.
Units of Measure: This is a drop-down menu option and you can choose from 7 options. For this example, it would be metre
1/f: This is the inverse Flattening of the Ellipsoid and is automatically populated based on the ellipsoid selected.
Map Projection: This is just text and does not directly affect any calculations - Transverse Mercator (Gauss-Kruger) Zone 3
Projection Type: This is a drop-down menu and you can choose from 4 options – TM, 1SP (Standard Parallel), 2SP or STEREO. In this example, choose TM.
False Easting: 500000.00 m.
False Northing: -5300000.00 m.
Latitude of Origin: This should be input as a decimal - 0.0000 deg.
Longitude of Origin: This should be input as a decimal - 19.0000 deg.
Scale Factor: Ratio between measured distance on the map and on the ground - 0.99930 deg.
1st Standard Parallel: This information will be required if you select 1 SP or 2 SP from the Projection Type Drop down menu - Not applicable here
2nd Standard Parallel: This information will be required if you select 2 SP from the Projection Type Drop down menu - Not applicable here
The Screen shot below is what your new CRS should look like based on the information detailed above:
Select Save CRS and your new CRS will be available to select from the mapping grid dropdown menu.
In addition to the individual Plan View, Section View and 3D View plots, Well Seeker also has a Wall Plot Composer (WPC), where different plots along with data tables can be displayed and then output together.
As with the individual plots, the WPC option only becomes available when the user is in a plan, survey, planned wellbore or actual wellbore.
The first thing to do in the WPC is to ensure that the page is setup as required. The default page layout will be A4 Portrait view. To change this, select File > Page Setup. The user can then choose sizes ranging from A0 to A7 or User Defined.
The user can then start to build the wall plot by inserting the desired Charts and Tables. This can be done by selecting Insert from the top menu or by right clicking anywhere on the plot.
Certain Charts and Tables can also be inserted from the tool bar along the top of the screen.
The offset selector in the WPC works in the same way as it does on the main Well Seeker menu. It is however completely independent, which means that offset wells selected in the main menu will have to be reselected when in the WPC.
Once a plot has been inserted into the WPC, the user can then open the Chart Properties by selecting a chart and either using the menu, Tools > Chart Properties, or the Chart Properties icon. This is where most of the chart functionality is located, and allows the user to add labels, change colours and customise the plot.
Once a plot has been inserted the user can then manipulate the size of the plot and position it appropriately on the screen. Dragging the plot to increase or decrease its size affects the scale. Once the user is happy with the size of the plot and its position, they can then select the appropriate scale and zoom in if required. Once the scale has been fixed the physical size of the chart will also be fixed and the user will no longer be able to grab the corners and drag to manipulate the chart size.
To zoom in, all the user needs to do is Left click and drag across the relevant portion of the plot. This will change the max and min axis values along with the scale. To Undo a zoom, right click on the plot and select Undo Zoom from the list of options, or alternatively press the z key.
Any time the plot box size is changed, or the user Zooms in, the Chart Grid section in the Chart Properties updates to match. In the below left, the plot was zoomed to show the point of interest. The chart scales are greyed out but match the plot. The plot was then manipulated (below right) using the chart scales option to fine tune the output.
It is important to note that any selection made in the Chart Grid section will be overwritten if the user changes the physical size of the plot or zooms in or out. When the user goes back into the Chart Properties after doing either of these things, the check boxes will have been unchecked and the greyed-out values will represent what is currently being seen on the plot.
Grid Lines can be added and manipulated from the Chart Properties. The user can also select the distance between major and minor tick marks on the plot. When a chart is first opened, the default is Auto and the boxes are greyed out and empty. To manually select these values the user needs to uncheck the Auto box, and they will then be able to adjust the line spacing as required. The grid line colour can also be selected from here.
In the File option at the top left of the WPC screen, the user can select to Save or Open an existing wall plot composer template. These templates are saved as .wpc files and allow the user to save the template they are working on and come back to it at a later date.
When a table is inserted into the WPC, it will be a fixed size. Like the plots, manipulating the border changes the size of the table. If the table has been stretched out of shape then the Reset Table Aspect Ratio button can be selected from the toolbar. This will keep the width of the table as the user set and alters the height of the table to set the table to the correct aspect ratio.
The Logo size can also be manipulated in the same way. However, the logo aspect ratio is reset using the Reset Logo Aspect Ratio button
The initial logo input will be the primary logo selected at Operator Properties in the database tree. Once input this image can then be changed to any image, so long as the image is a .bmp file. Insert the logo, then right click on the logo and select Select Image. The user can then select any .bmp file for inclusion in the wall plot.
The last four options on the toolbar are the alignment tools, which allow the user to line up the edges of items in the wall plot for neater presentation. The available options are left, right, top and bottom alignment. Select an item, click on one of the alignment tools and then click on another item. The first item will move so that its edge lines up with the second item.
It is possible to adjust the screen zoom. This option allows the user to zoom in, to look more closely at a particular section of the plot, or to zoom out to look at the whole plot. This feature can be accessed via the View menu.
This option is also available on the quick access toolbar along the top of the WPC screen.
It is possible to select plot defaults, which will be applied each time a plot is opened. These default selections are available on the main Well Seeker interface when a plan, survey or actual wellbore is open.
Select Plots from the toolbar along the top of the screen and the Chart Defaults options are available in the list. The selected defaults apply to the individual plots as well as the plots created in the WPC.
When viewing a plan, the well planning tools will be displayed at the bottom of the window.
Selecting one of the seven planning tools displayed will activate other options to configure the chosen tool. Once all options have been entered, click on the calculate button to add it to the well plan. Below is a description of each available planning tool:
The adjust planning method is a simple tool that will draw a curve with the minimum dogleg required to reach the desired inclination, azimuth and distance from the current point. The exception to this is the INC, AZI, DLS option – In this case the planning tool will calculate the build/turn values required to reach the desired inclination and azimuth while keeping to the desired dogleg.
MD, INC, AZI: Enter a MD, an INC and AZI in the text boxes in the parameters section.
CL, INC, AZI: Enter a CL, an INC and AZI in the text boxes in the parameters section.
INC, AZI, TVD: Enter an INC, an AZI and a TVD in the text boxes in the parameters section.
INC, AZI, DLS: Enter an INC, an AZI and a DLS in the text boxes in the parameters section.
The build / turn planning method is a 3D planning tool in which consecutive surveys have a constant build / turn rate between them. The well path produced by this method is effectively describing a trajectory travelling around a cylinder.
MD / CL: Enter an MD or CL, build rate and a turn rate and click on the “Calculate” button.
INC: Enter a build rate and a turn rate and an INC and click on the “Calculate” button.
AZI: Enter a build rate and a turn rate and an AZI and click on the “Calculate” button.
TVD: Enter a build rate and a turn rate and a TVD and click on the “Calculate” button.
The dogleg tool face method is a 3D planning tool where build rates and turn rates will vary between survey stations depending on the dogleg and tool face setting requested.
MD / CL: Enter an MD / CL, DLS and TFO and click on the “Calculate” button.
INC: Enter a DLS, TFO and an INC and click on the “Calculate” button. The trajectory will be calculated until the required INC is reached. If the INC selected cannot be reached, an error will be displayed.
AZI: Enter a DLS, TFO and an AZI and click on the “Calculate” button. The trajectory will be calculated until the required AZI is reached. If the required AZI cannot be reached, an error will be displayed.
TVD: Enter a DLS, TFO and a TVD and click on the “Calculate” button. If the TVD cannot be reached, an error will be displayed.
TANGENT: There are two methods available for the tangent option:
Tangent – HC (Hold Curve): The HC option draws a tangent section then a curve to hit the target
Tangent – CH (Curve Hold): The Curve Hold draws a curve to line up on the target then a tangent to hit the target
The Curve Hold method allows a larger number of targets to be reached. A NS, EW and TVD value must be entered. This can be done manually or by selecting an existing target. Lastly the DLS of the curve must be selected. If the target cannot be reached with the parameters specified, an error will be displayed. Usually increasing the DLS allows the target to be reached or changing the method from hold curve to curve hold.
POINT: Enter a NS, EW and TVD; this can also be done by selecting an existing target from the drop-down menu. The well trajectory will be turned using the minimum possible dogleg to reach the point. This method describes a constant curve to the target. If the required point is on an existing plan, this can be achieved by selecting plan from the target details section, choosing the relevant plan from the drop-down menu and selecting the appropriate MD. This MD relates to the point on the offset plan and Well Seeker will automatically populate the NS, EW and TVD based on this selected point.
The Hold function causes the trajectory to travel in a straight line at the current inclination & azimuth until at reaches the specified distance or depth:
CL: Enter a CL (Closure Length) and click on the “Calculate” button.
MD: Enter an MD and click on the “Calculate” button.
TVD: Enter a TVD and click on the “Calculate” button.
VS: Enter a Vertical Section and click on the “Calculate” button
The optimum align function is a powerful tool for lining up on targets at specified inclinations and azimuths. It is particularly useful if multiple targets are to be hit. The trajectory produced is usually a 3D S-shape profile, which can be defined either by specifying two curve sections and a hold or by using two curves. If “Curve Hold Curve” is used, the doglegs for both the curve sections must be specified. For a “Curve-Curve” method, only the dogleg for one of the curves must be entered. If “Balanced” is selected, Well Seeker PRO will attempt to create a profile using the same dogleg for both curves.
When selecting a point to hit, the user can choose any available targets from the drop-down menu or enter the N/S, E/W and TVD values manually using the user defined option. Then select the appropriate optimum align parameters and required dogleg, and enter the desired inc and azi and click on the “Calculate” button
If there are 2 targets and the user requires the plan to “line up” the first target with the second, the second target can be selected from the line up drop-down menu. Well Seeker will calculate the tangent inc and azi between the 2 targets and automatically enter these values into the relevant boxes.
It is also possible to line up on an existing plan. When Plan is selected, the user can choose the relevant plan from the drop-down menu and the relevant MD on the plan that they would like to hit. The coordinates and TVD of the point on the plan will be automatically entered and the inc and azi will mirror that particular point on the well plan.
If the optimum align method cannot reach the desired inc and azi at the target point, an error message will be displayed. Usually increasing the doglegs will allow the target to be reached.
If the user has multiple targets to hit, then one way to achieve this is by selecting the “Thread” function in the target details section. No planning method needs to be selected to open the Thread targets dialog; however, the feature utilises the Optimum Align functions when generating plans. Targets are available to select via a drop down menu at the top of the dialog, and the planning method options are selected at the bottom of the dialog.
The 2D well planning tools are designed to allow a well from surface to be planned with a single click. The 2D planning tools have multiple build /drop rates but only one horizontal plane (azimuth). There are two options available: S-Well and Slant Well. The S-Well profile can either be a standard S where the inclination is dropped back to vertical at the target, or a modified S where a specified inclination greater than zero is reached at the target. The slant well has a constant build up rate and a specified kick off point to reach the target.
To use this method, the KOP must be entered (the inclination will be vertical to this point), the DLS of the initial build (BUR 1) and then the drop rate (BUR 2).
The user then has two additional options to choose from, final inclination (Fin Inc) and final hold length (Fin Hold). The user can choose to select none, one or both of these options via the checkbox to the right of the corresponding cell. The final details required are the target NS, EW and TVD. These can be entered manually or by selecting a target from the drop-down menu. If the target cannot be reached with the specified parameters, a warning message will be displayed.
No Checkboxes selected: When the user does not select either the Final Inclination or Final Hold options, the drop section of the plan will stop at the selected target at an inclination of 0° (if this is possible). This will be referenced in the Method Column of the plan as SWELL_OPT1.
Final Inclination Only: When the user enters only the final inclination, the drop section of the plan will stop at the selected target at the desired inclination (if this is possible). This will be referenced in the Method Column of the plan as SWELL_OPT2.
Final Hold Only: When the user enters only the final Hold, the plan will hit the target at 0° inclination (if possible) and will have lined up at the given hold distance entered prior to hitting the target. In the below example, the plan has lined up at 0° inclination 100m MD before hitting the target. This will be referenced in the Method Column of the plan as SWELL_OPT3.
Final Inclination & Hold: When the user enters both values, the plan will hit the target at the desired inclination (if possible) and will also include a hold section prior to hitting the target. In the below example, the plan has lined up at 5° inclination 100m MD before hitting the target. This will be referenced in the Method Column of the plan as SWELL_OPT4.
To use this method, the KOP must be entered (the inclination will be vertical to this point) and the DLS of the build (BUR 1). The final details required are the target NS, EW and TVD. These can be entered manually or by selecting a target from the drop-down menu. If the target cannot be reached with the specified parameters, an error message will be displayed.
Once the survey has been entered, hit Save
When in a chart, to select an offset survey or plan, click on the Offset Selector. This will open the select offsets box and allow the user to select the relevant plan or survey.
Once these have been selected and the dialog box has been closed, the user can then display the offsets on the plot by selecting the Offsets On / Off button.
