6.6.1 - Plan Properties
The Plan Properties dialog will automatically open when a new plan is created. To access the Plan Properties for an existing well, right click on it in the Object Explorer.
The Plan Properties dialog has the below features:
6.6.1.1 - Properties
Name: The name displayed in the Object Explorer.
Description: A description of the plan used only for information purposes.
Set as principal: If this option is selected, a red box will appear around the plan icon in the database viewer. Only one principal plan per well can be selected per well. This plan will be used in the distance to calculations in the survey view.
Complete: If this option is selected, this plan will not be available to select in the Offset Selector. Use this option to hide drilled/completed wells to reduce clutter when selecting offsets in future wells.
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 Defaults ribbon.
Survey Tools: Clicking on this button will open the Survey Tool Editor. If the user selects a row in the survey program by clicking on its row number and then clicks on Survey Tools, they can use the ‘select IPM’ button in the Survey Tool Editor to choose an IPM for that row.
Force Colour: Located in the bottom-right of the dialog, toggling this option on will force this plan to always use the selected colour when displayed on charts. This supersedes any colour options for this plan in the ‘Chart Properties’ dialog.
Locked: This checkbox allows the user to lock all the editable cells in the dialog. If NO password has been entered at Operator level in the set password section, then the user can freely select to lock and unlock the dialog. If a password has been added at Operator level, then the user must enter the relevant password to both lock and unlock the dialog.
6.6.1.2 - Vertical Section
Details of the vertical section (used for section plots and vertical section calculations) are entered here. The VS azimuth and the origin point must be entered in order to correctly calculate vertical section. When Bottom Hole Location is selected, the program will draw a straight line from the VS origin point to the last planned point and the azimuth of this line will be used as the vertical section. It is important to note that if this is selected, the vertical section will change every time a new survey is added.
6.6.1.3 - Depth Reference
A list of depth references available to the well can be selected from the drop-down menu. The available depth references are defined in the Well Properties, one level up. If the depth datum is changed and there are currently surveys entered, a dialog will appear asking if you wish to change the TVDs or preserve them. If the user chooses to Change TVDs, the TVD values of the surveys will be changed in order to preserve the TVD Subsea values. If the user chooses to Preserve TVDs, the TVD Subsea values will change in order to preserve the TVD.
Note: Changing a depth datum with surveys already entered can seriously corrupt your data and a backup should be made prior to this.
6.6.1.4 - Magnetics
The magnetics grid allows the user to calculate geomagnetic data for the well location using any of the models available in the Well Seeker X magnetics directory. The geomagnetic data marked as Active will be used whenever ellipse of uncertainty need to calculated for the plan.
Date: The date used to calculate the geomagnetic data. This input is required if the user is using any model other than User Defined.
Model: Select the desired geomagnetic model from the dropdown box. By default, the IGRF and WMM models will be available. If your organisation has purchased the BGGM or HDGM models, contact Innova support ([email protected]) for instructions on how to integrate them into Well Seeker X. The user my also select User Defined, allowing them to manually enter the declination, dip and total field values.
Declination, Dip, Total Field: These values will be automatically calculated using the selected model, date entered into the Date field, and the surface location of the plan. If User Defined was selected as the model, these values can be manually entered.
Active: Only one row can be marked as active at a time. The active row is the one used to ellipse of uncertainty for the plan.
Export Geomag Data: Located to the bottom-right of the Magnetics grid, this option exports the geomagnetic data as a document. Select the line in the ‘Magnetics’ section that you want to export the geomagnetic data for. Then select the report format as ‘PDF’ or ‘Excel’ from the drop down menu, before selecting ‘Export’ to generate the report.
6.6.1.5 - Survey Program
The survey program specifies how the planned wellbore is constructed and which IPMS’s will be used to generate error ellipses.
Normally the survey program is constructed automatically when the user saves their plan in the Plan View. However, the user may need to manually reconstruct the plan to resolve and error, or split it into sections that use different survey tools.
Rows in the survey program can be deleted by clicking on their row number and then pressing the delete key on your keyboard. In a new row, start by selecting the plan from the dropdown box in the Survey column. The Depth From and Depth To columns will populate down to the deepest point on the plan. If the plan is split into multiple rows, these can be edited to define the depth range of each row.
Lastly, the survey tool for each section of the plan should be selected from the dropdown in the IPM column. If the select survey tool is highlighted in red, it means that the required IPM file is missing on your PC. The Survey Tool Editor can be opened by clicking on the Survey Tools button at the top-right corner of the dialog.
If the plan is a sidetrack of another well or plan, the survey program from the motherbore will be included in the survey program, down to the tie-on point. These rows will be greyed out and un-editable.
6.6.1.6 - Tie-On / Sidetrack Details
The plan can be turned into a sidetrack of another well or plan using the options in this section. Follow the process below to turn the plan into a sidetrack. A more detailed explanation can be found on Well Seeker X: Sidetrack Guide
Click on Plan is tied to, to activate the other features.
Use the Parent Well / Plan to select the motherbore that this plan will be tied to. Only actual wells and plans under the same well will be available.
Enter the tie-on/kick off depth of the sidetrack in the Tie On/ST Depth box. This is referenced to the depth reference of this plan, not the parent well.
Choose an option from the Errors Start dropdown. This sets where anti-collision ellipses begin when running anti-collision between the sidetrack plan and it's mother bore. If ST Point is selected, the error ellipses for both will start at the sidetrack kick-off point, with an initial magnitude of zero. If Surface is selected, the error ellipses will start at surface as normal. If the plan was imported from a Compass EDM file, this option will match the choice in the EDM file. Otherwise, it will default to ST Point. Note that this only applies to anti-collision run between the mother bore and the sidetrack. For anti-collision scans against any other well or plan, the errors will start from surface.
Click on the Create Tie-On/ST button. This will update the survey program with all the surveys up to the side track point from the parent well. It should be noted that all previous survey program lines will be deleted.
6.6.1.7 - Tie-On
Tie-On: This section specifies where the plan will tie on to:
Surface: The plan will tie on to the well head location
User defined: The user can enter the MD INC AZI NS EW and TVD the plan will be tied on to.
From survey / plan: This option is only available if the plan is a side track, select the survey file of plan to tie on to and type the MD which you wish to use. The INC AZI NS EW and TVD will be interpolated from the survey or plan selected.
