Abstract

Since PETRONAS Carigali Sdn Bhd (PCSB) has taken over Block XYZ in 2003, 3010 sq km of 3D seismic data were acquired and merged with existing 3D data acquired earlier over the producing fields. Currently, almost 80% of the block XYZ acreage is covered by 3D seismic data. The new data provides an outstanding opportunity to integrate the geology interpreted separately over the producing fields. From the available data on these groups, Group L and M has been identified as a potential new play and enhancing the stratigraphic trap in the south of Malay basin. PCSB has drilled eight wells deep down into the lower Group M, M110 and discovered oil and gas. The new oil and gas discovery in the southeast area of Block XYZ has proved that valid petroleum system is present in the deeper groups. Group L & M reservoirs have been identified as potential hydrocarbon play in Block XYZ. Seismic facies interpretation is very useful to investigate this concept. Group L and M are deposited in the earlier stage of the basin formation (synrift), which is in fluvial lacustrine environment (EPIC report, 1994). A seismic facies project have been conducted with the aim to describe the seismic facies in the study area and to interpret the depositional setting of these deeper groups in Block XYZ by integrating seismic facies characteristics on 3D seismic data, well log and core data from key wells. It also aims to provide an improved understanding of the local and basin scale distribution of potential reservoir sands in the southeastern part of the Malay basin.
