  1. Course 3: Using Basic Well Editor Tools

  2. Can open multiple files and sort by different parameters

  3. Change – applying a constant value to replace Select curve> Identify start and end points

  4. Manually draw in a curve; linearly interpolated Multiply log values over a specified interval by a value

  5. Replacing values with the average 1st click and hold Drag over values Release to mark first point Mark end of this int and successive ints by

  6. 1st click and hold Drag over values Release to mark first point Mark end of this int and successive ints by a horizontral green line

  7. Insert a constant value Multicurve then insert from the edit menu Specify a starting point This will shift the curve down Have user specified value, interpolate or null

  8. Remove log data from a specified interval Shift start depth Edit > Multicurve > ShiftData is either shifted up or replaced with nulls. Shift down (+) up (-)

  9. Shift start depth by specified amount

  10. Stretch and Squeeze

  11. Smooth curve (3 filter types and filter length changes)

  12. Edit formation tops

  13. Edit > formation tops Click in KB cell then click the top location from one of your logs. Click and refresh to display new top picks

  14. Edit > Curve Header, Define Curve and Create Lithology Strip

  15. Curve mnemonic by default Change curve label to SONIC WET

  16. As a footnote: when generating AVO synthetics, the foregoing comes in handy. Edit > Curve Header Select PR Edit Label/Type Define curve category as Poisson Ratio OK

  17. When first reformatted Curve params read Define curves dialog are based on options sleeted in the well editor preferences dialog Edit > Curve Header Select SFL > Define curves

  18. Select SFL > in userdefined list Change curve label to Spherically Focused Resistivity > Append

  19. Append adds the label to the user defined curves list OK to exit > close edit curve header panel

  20. Getting Started on AVO Synthetics

  21. http://www.crewes.org/ResearchLinks/ExplorerPrograms/ZE/ZEcrewes.htmlhttp://www.crewes.org/ResearchLinks/ExplorerPrograms/ZE/ZEcrewes.html

  22. Poisson ratio =0.33/0.33

  23. AVO.xls

  24. Poisson ratio =0.33/0.19

  25. Redefine curve mnemonic> add spherically focused resistivity to the user defined curves list

  26. Create lithology Strip View > Track paramters Select all 4 tracks (click and Shft Click Change track width and Gap width Apply Select all 4 tracks

  27. Change curve label and click in the area between tracks to insert your lithology curve > Insert here Edit > Lithology Track

  28. Click on the Course Lith track and click on the top to auto fill the start depth. Do the same for the base (end depth). Use scroll bar to select patterns and apply to fill lith track with color. The proceed as before clicking in the start and end depths and lithology patterns

  29. File > Save as > Log M Well

  30. Well ID has been changed to reflect display content.

  31. Generic curve fills only need to be defined once and are defined in all wells displayed in cross section Zoom all to fit curves to window

  32. View > select curves Note more than one curve per track OK to display

  33. Edit > Curve Fills

  34. Well Specific Well Editor > Open well > Select well > OK Zoom all > View > Select Curves From select curves to display dialog
