Figure 7. A. Cross-section, Columbus basin: 4^th order sequence between maximum flooding surfaces below and above sand-rich interval defined by a basal unconformity (58) (from Sydow et al., 2003, with kind permission of GCSSEPM Foundation, Norman C. Rosen, Executive Director). Interval demonstrates growth across faults, with the largest at or near the shelf edge.
B. Seismic Line A, East Venezuela shelf / Columbus basin (location in Figure 8): shelf-edge trajectory of the SEG reservoir interval shows lateral (progradation) and vertical (aggradation) components (from Sydow et al., 2003, with kind permission of GCSSEPM Foundation, Norman C.
