Comprehensive preliminary reservoir studies and subsequent detailed geological analysis and surveillance programs were combined to plan and implement an efficient depletion scheme for the Pulai Field. A highly sophisticated three-dimensional mathematical model was developed to provide effective reservoir management. Model predictions shown an incremental recovery of 10 1% the original oil-in-place through implementation of a gas injection scheme. Drilling of four additional wells in the two major sands provides an additional recovery of 7% of the original oil-in-place. The models will be periodically updated as production progresses and new information becomes available through development drilling. Revised predictions from the updated models will be used in our continuing optimization of the Pulai Field.
