All charts are a graphical representation of a reference data set. Which data set the chart is referenced to depends upon the actual well, survey, plan or planned wellbore that is currently open and selected by the user when the plot is opened.
Right clicking anywhere on the chart area brings up the chart menu which allows the user to customize the chart as they wish. Grid options, legend style and position as well as font size can be changed. The Maximize option allows the user to make the chart full screen size, pressing the escape key returns the chart to normal size. The customization dialog allows the user to control all aspects of the chart including the series colours, chart colours and various other styles.
The export dialog allows the user to print the chart directly to a PDF, jpg or other file format.
Additionally, the charts can be edited in the Chart Properties dialog. For more information on the chart properties dialog see section 6.7 - Chart Properties.
Many of the settings that can be edited in the chart properties dialog can be set by the user so that they are already selected by default upon opening a chart. For more information on this feature and additional chart functions see section 6.6 – Plots Menu.
A side slice view of the well, plotting TVD vs Vertical Section on a specific vertical section azimuth. The
The plot can be zoomed by scrolling the mouse wheel. When zoomed in the ↑, ↓, ← and → keys scroll the view in the corresponding direction. The view can also be scrolled my left clicking and dragging the mouse. The zoom can be reset via the context menu or by pressing the Z key.
Right clicking on the chart brings up the Context Menu and double left clicking anywhere on the chart opens the chart properties dialog.
A top down representation of the well, plotting North/South vs East/West local coordinates.
The plot can be zoomed by scrolling the mouse wheel. When zoomed in the ↑, ↓, ← and → keys scroll the view in the corresponding direction. The view can also be scrolled my left clicking and dragging the mouse. The zoom can be reset via the context menu or by pressing the Z key.
Right clicking on the chart brings up the Context Menu and double left clicking anywhere on the chart opens the chart properties dialog.
Displays a 3D representation of the well path, plotting North/South vs East/West vs TVD.
The chart can be rotated and panned around the centre point using the mouse with the left mouse button depressed. The centre point can be adjusted by holding Shift and using the mouse with the left mouse button depressed.
The plot is zoomed in and out using the + and – keys or the mouse scroll wheel. The { and } keys can be used to decrease or increase the well line thickness as required.
The 3D chart has a slightly different right click chart menu to the other charts.
The legend display, rotation animation settings and plotting method settings can all be adjusted from the 3D chart menu.
The Center on survey and Fly down well options will zoom and centre the 3D plot on the reference well when selected. The Center on survey option will allow the user to manually move along the wellbore points using the ↑ and ↓ keys. The Fly down well option will move through the wellbore points automatically at a speed that can be manipulated by using the ↑ and ↓ keys and be paused and restarted using the Spacebar. In this state the chart displays the reference well point coordinates data and the up/down, left/right and centre to centre distance in relation to the currently selected offset well. The North Ref Distances option will toggle this distance between high side reference and north reference. The offset well can be individually toggled through all the currently displayed offset wells using the < and > keys.
If necessary, the ← and → arrow keys can be used to toggle the displayed reference well to any of the currently displayed offset wells. This allows the user to change the reference well without having to come out of the chart, open a different well and then open a new chart.
When Centre on survey or Fly down well is selected the Show closest approach option can also be selected, displaying a line between the reference and offset well and labelled with centre-to-centre distance between them at that point in the reference well.
The Go to bottom of well and Go to top of well will send centre the view at the bottom or top of the well, respectively.
A specialised anti-collision plot that shows the relative distance and bearing of offset wells. For more information on the travelling cylinder scan method see section 8.2 - Level 2: Operator.
To correctly use a TC plot, the user must have Travelling Cylinder or Travelling Cylinder North selected at operator level as the scan method.
Travelling Cylinder if HS is the reference.
Travelling Cylinder North if North is the reference.
TC Plot Safety Factor: This option allows the user to apply a safety factor to the errors which are generated in the travelling cylinder plot. With a value of one entered here (default), the ellipses will generate as per normal i.e. no safety factor applied, which means touching the No-Go line on the plot effectively equates to a SF of 1. If the user enters a value of for example 1.2 here, the ellipses displayed on the TC plot will be 20% larger, 1.5 will be 50% larger etc, giving the safety factor required. Note: This value cannot be anything less than 1.
The centre of the plot is the centre point of the reference well. The selected offset wells will display over the entire depth range of the individual offset wells, unless a depth filter has been applied. In the TC plot, errors are generated by adding the semi major errors from the reference and the offset and displaying this around the offset.
The user should set the reference to either north or high side in the Chart Properties, depending on the chosen scan method. The default reference can be selected in the Anti-Collision Settings, which is accessed via the Tools menu.
The depth range over which the TC plot displays offset well data can be selected by the user in the Anti-Collision Settings dialog. For more information regarding the anti-collision settings dialog see section 6.4.5 – Anti-Collision Settings.
The plot can be zoomed by dragging an area with the left mouse button. Right clicking brings up the chart menu and clicking Undo Zoom resets the chart. Pressing the Z key also resets the zoom.
Shows the relative centre to centre distances of the offset wells to the reference vs measured depth.
The plot can be zoomed by dragging an area with the left mouse button. When zoomed in the ↑, ↓, ← and → keys scroll the view in the corresponding direction. The zoom can be reset via the context menu or by pressing the Z key.
A zoom window will appear at the bottom of the chart to allow the user to select which part of the chart they wish to view once zoomed in.

For more information regarding the offset selector see Section 6.4.7 – Offset Selector.
