Grid a time surface from seismic interpretation and no faults.

  1. Display interpretation lines from 02_Time data > Interpretation lines > 02BasePliocene.
  2. Apply the command Simple points and lines gridding
  3. Click Update window to get the project window as the grid window.
  4. Set x and y increment to 500.
    Info
    titleGrid window for Course B1
    • xmin = -188000, xmax = -47500; ymin = 7864500, ymax = 7959000
    • Using grid increment 500 gives as size of grid: number in rows: 282 , number in columns: 190
    • It is a relatively small grid, but useful in a course and the size of the project is kept reasonable low.
  5. Use gridding algorithm Parabolic (default).
  6. Check in for *Use two steps gridding". Grid increment will be automatic calculated if blank.
  7. Set moving average as gridding algorithm for 1. step.
  8. Click Execute. The result will be written to the same folder.
  9. Click OK and save the panel with all parameters.
  10. Create a new folder for interpretation grids and cut/paste the result grid into this folder.
  11. Display the result as shown below.

titleGrid menus using faults
  • The grid menu when faults are included is Gridding points, lines and faults. This menu can also be used when there is no faults, but the one we used is a simpler alternative.

Grid a time surface from seismic interpretation and closed stick faults.

  1. Display 02_Time data > Faults > 07SilurianFaultInt_Polygons. This is how the fault polygons comes from Kingdom. They must be edited.
  2. Use Edit points and lines to remove the blobs. See Case study - Gridding of seismic interpretation data with faults.
  3. The correct edited fault lines are in 02_Time data > Faults > CorrectedClosedFaults. Use this if you don't have time to complete the editing.
    Tip
    titleTips when editing fault lines with _blobs_
    • To remove the blobs just delete the two extra points in the blobs.
  4. Apply the command Gridding > Gridding points, lines and faults.
