Review of the wells logs, cores and the reservoir performance emphasized on the need to revise the infill drilling program of the reservoir. The well logs have been looked into for ascertaining the oil water contact. Image logs have been used for Paleocurrent studies for chasing the extension of the reservoir and for pinpointing the infill locales of drilling. New logging tool-3DEX has been used for interpretation of thin sand shale intercalations.
The results of infill and other wells drilled so far have revealed the extension of the pay sand within and outside the foot print of the reservoir, encountering top of the reservoir relatively at shallower depths and deepening of the OOWC. All these culminated in an upward revision of STOIIP and Reserves; thereby an improved development strategy for the optimization of production of the reservoir has been formulated
