Time-lapse 3-D seismic monitoring of subsurface rock property changes incurred during reservoir fluid-flow processes is an emerging new diagnostic technology for optimizing hydrocarbon production. I discuss the physical theory relevant for three-phase fluid flow in a producing oil reservoir, and rock physics transformations of fluid-flow pressure, temperature and pore-fluid saturation values to...

The paper discusses the problem of localizing zones high pore pressure in sub-bottom sediments (first tens meters under seafloor). Prediction overpressure near-surface is required for mitigation risks at early stages offshore hydrocarbon field exploration and development. results seismic data interpretation generally serve as main source information this kind problems, yet there are other metho...

A rock physics model was established to calculate the P-wave velocity dispersion and attenuation caused by squirt flow of fluids in gas hydrate-bearing sediments. The critical hydrate saturation parameter introduced describe different ways concentration, including mode pore filling co-existence particle cementation. Rock physical modeling results indicate that is insensitive increase for fillin...

S U M M A R Y Many unresolved questions in geodynamics revolve around the physical behaviour of the two-phase system of a silicate melt percolating through and interacting with a tectonically deforming host rock. Well-accepted equations exist to describe the physics of such systems and several previous studies have successfully implemented various forms of these equations in numerical models. T...

SUMMARY An evaluation of prospective shale gas reservoir intervals in the Bowland Shale is presented using a wireline log data set from UK's first exploration well. Accurate identification such crucial determining ideal landing zones for drilling horizontal production wells, but task challenging due to heterogeneous nature mudrocks. This heterogeneity leads stratigraphic variations quality and ...
