A rock physics based seismic interpretation workflow has been developed to extract volumetric properties from seismically derived P- and S-wave impedances, I p s . This was first tested on a classic velocity-porosity model. Next, it applied two case studies: carbonate clastic oil field. In each study, we established models that accurately relate elastic the rock’s properties, mainly total poros...

Digital rock physics (DRP) is a newly developed method based on imaging and digitizing of 3D pore and mineral structure of actual rock and numerically computing rock physical properties, such as permeability, elastic moduli, and formation factor. Modern high-resolution microcomputed tomography scanners are used for imaging, but these devices are not widely available, and 3D imaging is also cost...

Seismic analyses of methane hydrate data from the Blake Outer Ridge indicate high Pwave velocity and anomalously low S-wave velocity in sediments containing methane hydrates. In an attempt to explain this observed P-wave and S-wave velocity structure at the transition from gas to hydrates, the effect of different hydrate models on elastic moduli and velocities are explored. After construction o...
