Figure 9. Reservoir block control on the development of a diagenetic polygonal fault network. (A) Interpreted seismic section showing separated reservoir blocks flanked by normal faults that coincide with the nucleation point of polygonal faults within the overlying mega-unit (Mu) D1. The location is shown in Figure 5. (B) Variance time slice at −1210 ms two-way time (TWT) showing the network of polygonal faults that have formed within Mu D1. The location is shown in Figure 5B. (C) Schematic diagram depicting the influence of reservoir block location on the development of polygonal faults and larger offset normal faults.
