Pre-Carbonate Imaging: A Successful and Innovative Seismic Processing Case Study

Pre-carbonate imaging is challenging due to rugosity associated with the top-carbonate surface but is essentially required to determine the deeper prospectivity in the Cycles I and II clastics. Poor images previously were undermining the prospectivity. Our integrated data processing approach managed to address these critical imaging issues and we were able to successfully see the pre-carbonate sequence and 32+ leads and prospects were identified. Our processing workflows produced final migrated images that have significantly enhanced our understanding below the carbonates and mapping of these prospects will lead us to mature these prospects into drilling locations and will hereby increase the acreage value for PETRONAS.
