f Convergence Towards Reducing Exploration Stratigraphic Play Risks

Much geophysical analyses have been conducted on the northeastern flank of the Betty field. This flank covers the extension to the east, the slightly deeper Betty Timur area where hydrocarbons were found in the same Miocene formation as that of the Betty field some 11 km away. The earlier relatively simple analysis using full-stack acoustic impedance data led to the identification of a number of potential hydrocarbon-bearing geo-bodies which could only be valid if explained from a stratigraphical trapping mechanism. The availability of shear sonic logs in the Betty Timur recent wells and the angle sub-stacks of the seismic data afforded us more rigorous analyses using a number of techniques to reduce uncertainties in the search for potential hydrocarbon-bearing zones.
