Gridding and surface modeling.
Grid models are essential in modeling reservoirs. Good grid models require good input and well tuned algorithms.
In this exercise we will use as input seismic interpretation lines and closed stick faults.
Exercise
Grid a time surface from seismic interpretation and stick faults.
- Display 02_Time data > Faults > 07SilurianFaultInt_Polygons. This is how the fault polygons comes from Kingdom. They must be edited.
- Use Edit points and lines to remove the blobs. See Case study - Gridding of seismic interpretation data with faults.
- The correct edited fault lines are in 02_Time data > Faults > CorrectedClosedFaults. Use this if you don't have time to complete the editing.
Tips when editing fault lines with _blobs_
- To remove the blobs just delete the two extra points in the blobs.
- Display the seismic navigation lines. Use the icon Locate project object from graphics to identify a seismic section.
- Display interpretation lines in various line thickness. Try also point display.
- Evaluate the interpretation quality. Are the lines auto tracked or digitized?
Seismic 2D sections and navigation lines
Detail of seismic and interpretatin lines
If you want to correct or reinterpret some parts of the interpreted lines they have to be imported into Geocaps interpretation systems; see Importing Interpretation and Seismic Interpretation.Not all seismic 2D sections are in the course project, but they are present in the Tutorial data1 which can be downloaded.
