Seismic inversion of a carbonate buildup: A case study

The information within seismic data is band limited and angle limited. Together with the particular physics and geology of carbonate rocks, this imposes limitations on how accurately we can predict the presence of hydrocarbons in carbonates, map the top carbonate, and characteriz... Read More.

Predicting pore pressure in carbonates - a review

Carbonate reservoirs are the targets of many drilling programs in the Middle East. One of the challenges in developing these types of reservoir is to mitigate the risk caused by unexpected pore pressure - these pressures can vary dramatically from relatively benign (e.g. Arab C a... Read More.

Rock physics workflow including Xu-Payne - UK North Sea

D.M. Hammond and S.S. Payne present an application of the new Xu-Payne model, which classifies carbonate rocks as dual porosity systems, to investigate the fluid effects within the chalk play of the Central Graben for quantitative seismic interpretation. The model was calibrated ... Read More.

Carbonate rock physics modelling in practice

Approximately 50% of the world’s known hydrocarbon reserves are contained in carbonate reservoirs. Central to the seismic characterization of carbonate reservoirs is an understanding of the effect of porosity on the elastic moduli. Carbonate rocks are known to exhibit heter... Read More.
