Investigation Of Lcrc Reservoir Using Multicomponent Seismic Data And Low Gas Saturation Model

Multicomponent seismic data is used to identify, as well as to study, the distribution of the low-resistivity low-contrast (LRLC) hydrocarbon reservoir. Three attributes were derived i.e Attenuation, Density and Difference Impedance from a Malay Basin gas field multi component (3C) data. The three properties based on the laboratory low-saturated-gas (LSG) model by previous researcher was analyzed. It was found that all three approaches are able to locate the reservoir gas sand which associate with low-resistivity logs data value or apparently show no gas sand anomaly. This study informs that the field is abandon of thin 7% saturated gas gas reservoir sands. A 25 % gas sand, which is not anomalous in well log, is clearly delineated.
