The plots menu allows the user to bring up a plot for the currently selected plan / survey.
Plan View – Top down plot showing a bird’s eye view of the well / wells
Section View – A slice at the reference well’s vertical section azimuth
3D View – A 3D representation of all wells
Travelling Cylinder Plot – A specialised polar plot used for anti-collision; requires at least one offset well to be selected.
Separation Factor – Shows separation factor vs measured depth; requires at least one offset well to be selected.
Ladder Plot – Shows the centre-to-centre distance vs measured depth; requires at least one offset well to be selected.
Spider Plot – Similar to a plan view except “TVD slices” can be produced whereby only the current well bore sections which have a TVD greater than or equal to the current value are displayed. This plot is used to help with anti-collision. Using the “+” and “-“ keys changes the current TVD slice. This can also be done from the chart properties menu.
Azimuth Comparison – Show azimuth vs measured depth.
Inclination Comparison – – Show inclination vs measured depth.
Dogleg Comparison - – Show dogleg vs measured depth.
Turn On Error Ellipses– Turns On / Off the error ellipses in whichever chart is currently displayed.
Chart Properties– Brings up the chart properties dialog which allows the user to customize chart settings. See section 6.7 - Chart Properties for more details
Screen Reader – Allows the user to turn the screen reader on and off. The screen reader is not available in 3D plots.
Chart Figure 108: Screen Reader
The screen reader will display the co-ordinates of the current mouse position in the top left-hand corner of the chart. If the user clicks on the chart area, a red line will be drawn from the point which was clicked to the current mouse position. The distance between the current mouse position and the point at which the mouse was clicked will be displayed in the distance box of the screen reader, as will the angle (azimuth) between the 2 points. Turning the screen reader off will remove the red measuring line.
Reset Zoom – Reset the chart view to default zoom levels
