Log-based prediction of pore pressure and its relationship to compressional velocity, shear velocity and Poisson’s ratio in gas reservoirs; Case study from selected gas wells in Iran

A precise identification of pore fluid pressure (PP) is great significance, specifically, in terms drilling safety and reservoir management. Despite numerous work have been carried out for prediction PP oil reservoirs, but there still exists a tangible lack such gas hosting rocks. The present study aims to discuss evaluate the application number existing methods two selected giant carbonate reservoirs south Iran. For this purpose, was first estimated based on available conventional log data later compared with suggested by Reservoir Formation Test (RFT) other bore data. At end, it has revealed that while highly dependent type litho logy carbonates, effect negligible. Moreover, velocity correlations more efficiently pure limestone/dolomite mixed ones.
