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 and activate it on the proper interpretation lines.
  • Don't alter type of input data (under development). Use default: Single points.
  • Click Use active window to get the project window into the grid window.
  • Set the x and y increment to 500. Click Adjust to Increment to secure that the grid window is adjusted to the increments. If the grid window changes update the project window in Project Settings. It is an recommended that the project window and grid window are equal and adjusted to the grid incrments.
  • Click Calculate to get number of elements in rows and columns: 282 x 190
    *.
  • Go to the Fault Input tab.
  • Check in Closed stick faults and browse in: 02_Time data > Faults > CorrectedClosedFaults
  • Clik Test at bottom to do the blanking test. The fault polygon should be filled inside. No lines outside.

  • Go to the Grid options tab.
  • Check in Use reference grid or outline and browse in: 01_Cultural > Boundary border_line.
  • Check in Use two gridding steps.
