MAASTRICHTIAN- THICK SAND PACKAGES IN CORENTYNE BLOCK Strike line through Kawa-1 Kawa-1 The potential for thick reservoir development is evident at Kawa-1 PAY PAY • Several stacked blocky sands over 600-foot interval; mappable sand package 100 feet • High Net-to-Gross sand ratio Sand package drilled
Slide 14: Maastrichtian - Mappable and Predictable
MAASTRICHTIAN- MAPPABLE AND PREDICTABLE Mapping Methodology • Extensive core and log dataset from Wei Perspective diagram of two intersecting seismic lines and a map of a Maastrichtian was used to calibrate with seismic to horizon. This is displaying just one of many horizons in the Maastrichtian. c
