Figure 12. Prospect A was a play extension and exhibited classic direct hydrocarbon indicator (DHI) attributes. With moderate discernibility, geophysical evidence modified the iCOS value higher than GCOS. Clockwise from upper left: (A) geological description, (B) well results, (C) rating values from the three systems and prospect discernibility matrix, (D) iCOS integration graph with prospects colored by discernibility, (E) seismic profile across contact, and (F) minimum amplitude (AMIN) map. Proposed oil-water contact (OWC) is annotated.
