Study of Rock Physics and Seismic Attributes of Hydrocarbon Reservoirs in Sabah Basin

Elastic moduli are known to discriminate fluid and lithology for effective reservoir characterization. However, in some cases, the elastic modulus can also show the same response for different type of fluid and lithology. In our study area, a few elastic moduli were used to evaluate the hydrocarbon...

Elastic moduli are known to discriminate fluid and lithology for effective reservoir characterization.
