The Irong Barat field, located offshore Peninsula Malaysia, has been producing since 1984 from the Irong Barat-A platform. Production in the field, which is complexly faulted with major and minor faults dividing the field into four major fault-block compartments, is primarily from the Group H channelized facies reservoir. The increased complexity in structural interpretation and reservoir mapping as a result of the complex faulting posed a challenge in managing risks and uncertainties in developing and maximizing asset value of this field.Upon successful initial development of the primary fault block, additional data was acquired to mature further opportunities resulting in additional field development at Irong Barat particularly the IBA Redevelopment, and the Irong Barat B and Irong Barat C developments Integration of reservoir surveillance/studies, geological and geophysical analysis, facilities and drilling technologies was applied by Irong Barat Teams to mitigate the risks and uncertainties of the identified development opportunities. As a result of this effort and over the last six years, crude production has increased from 10,000 to 25,000 barrel per day and developable reserves has grown by about 50 million barrels, more than 30% of the originally developed reserves.This paper describes the integration of key technology and approach taken to manage the risks and uncertainties in these projects to increase the Irong Barat field asset value.
