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...

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...

It is generally accepted that the identification and characterisation of discontinuities in discontinuous rock masses is one of the most important aspects in rock mass modelling. Traditional manual field survey methods for gathering discontinuity properties are biased, hazardous, difficult and time-consuming. This paper describes a computer approach, based on terrestrial laser scan data, which ...
