Finding Fault Cuts
Locate the position of the faults and the amounts of the fault cuts on the logs from the
northern Gulf of Mexico (Fig. 7.40) based on the type log in Fig. 7.39. Example cour-
tesy of Jack Pashin (Pashin et al. 2000).

Correlating Fault Cuts
Contour a fault (Fig. 7.41) that includes all four wells that cut faults. Is the fault surface
obtained reasonable? What is the attitude of the fault plane given by the three
