Presentation Transcript

  1. Well section display and formation top correlations • Objectives for the week • Import well log las-file data • Create cross sections • Wednesday • Revise formation top picks • Evaluate real-time updated picks in 2D and 3D interpretation windows • Get started on well top correlation exercise • Two exercises (12 and 13) but only one submission. It will be a combined assignment. Everybody successful?

  2. You can also check to ensure that the logs were imported from the correct file

  3. On to - Well Section Display

  4. There are a couple ways to create a new well section window - Stratigraphic modeling> Well correlation

  5. You can pick a template from a list or specify a new one: e.g. Stratton ..

  6. Partition wells to sections as shown belowthis parallels the GeoGraphix effort Using this option you would compile a list of wells to be used for cross section display. To illustrate, we’ll use the same sections we did in GeoGraphix East NS: Wells 7,8,10,14 and 19

  7. List wells on the three additional sections Northern EW: 1,16,9,20,2,8 Central EW:12,18,11,5,10 Southern EW: 17,21,6,13,4,15,3,19,14

  8. Check on wells in section view. Check on in the order they appear in map view.

  9. Then turn on the logs you want to display from your Global well logs drop

  10. Again – turn on logs you wish to display in section view

  11. Toggle synchronized well scrolling Place mouse in the depth track. A hand will appear and you can shift all logs up and down together.

  12. RC > Open template settings > Stratton& update current template

  13. Double click SP

  14. Open Curve filling tab Add new curve filling

  15. Specify as shown below and apply

  16. Do similarly for the  ray log

  17. Have a look

  18. Revise or change color fill display as desired

  19. Zoom in/out Be sure to synchronize scrolling and scaling To zoom in click and drag the line on the depth track separating the gray and white areas

  20. A second approach is to create a well section directly from the 3D (or 2D) display window Be sure existing well sections are turned off (not bold) Click on the well icon and begin clicking on wells to select. A well section view will automatically open and become populated by wells you pick

  21. If you do it this way, make sure existing sections are not highlighted (bold in window list)

  22. Select the Stratton template

  23. Flatten on a specified depth to line up

  24. New Section Display

  25. Finally – Add new well section window >

  26. Add New well section window

  27. A blank section display window appears

  28. Get into the section settings and select wells from your input well tree in the order they should appear (west to east) on the section line

  29. With template selected and well list specified > OK to display

  30. Set Spacing to 10 for this long section

  31. That’s the last section for us: rename to Southern EW

  32. Foot Note … log label formats

  33. Flatten on well top: RC > Well Section > Settings > select flatten on well top and select the well top you want to use.

  34. Flattened on B46 Remember the drill? What do you think of the BEG picks?

  35. For the remainder of the day • Finish creation of your well sections and get them ready for use in class on Wednesday. • Work through Exercise 12. This needs to be completed to pursue Wednesday’s efforts in Exercise 13. • On Wednesday we’ll explore formation top picking functionality and revise picks in a manner parallel to that undertaken in GeoGraphix.
