Regional Scale Rock Physics Modeling for Quantitative Analysis of Seismic Amplitudes in the Malay Basin, Malaysia

The objective of this study is to build a rock properties database and to understand vertical and lateral trends which can<br>explain seismic amplitude response(s) in terms of lithology and fluid fill in the Malay Basin. The elastic rock properties,<br>defining the seismic response were extracted from the logs of 60 wells distributed throughout the Malay Basin. To ensure<br>high quality of elastic logs, each well underwent iterative petrophysical and rock physics analysis to produce high quality<br>elastic logs (Vp, Vs, and density) and consistent petrophysical logs (mineralogy, saturation, porosity, etc.).
