Tom Wilson, Department of Geology and Geography Objectives for the DayAssignment discussion Use Petrel attribute processing to highlight seismic discontinuity in your 3D data Map “fault patches” in your data set and filter them using stereo net and histogram based selection criteria Will try to get out a little early so you can get down to the EQT info session and meet up with the crowd for pizza and beer

The 3D view helps us pull fault correlations together or apart Tom Wilson, Department of Geology and Geography It’s difficult to tell from the 2D views (even in 3D volumes) and until you begin to pick them it’s hard to interpret subtle faults based on subtle structure (horizon or surface).
