Abstract

Newfield is trying to be commercially successful in the developments of thin oil transition zones with gas caps in the East Belumut Field off peninsular Malaysia. East Belumut lowstand (LST) braided fluvial sand is extensive with high quality reservoir properties. The transgressive (TST) subtidal sands and shales increase heterogeneity along top of the reservoir. Production sand screens and inflow control devices (ICDs) should improve production contribution along entire wellbore. Restricting total fluid production is needed to manage pressure drawdown and gas and water coning. Horizontal wells are required to maximize drainage with a consistent height above OWC (or below GOC) is critical for managing gas and water coning. It is necessary to have independent checks on survey TVDSS computations while drilling. ECD management is critical to obtain maximum horizontal borehole length. Initial East Belumut production performance exceeded simulation model predictions.
