In this study, the deterministic approach involved a systematic solution of a series of equations that established crucial correlations between various formation attributes and corresponding log measurements. The methods used for computing porosity from neutron...

This approach capitalizes on BHIs for multiple analyses, including structural dip assessment, fault and fracture identification...

.... Their thickness ranges from 100 to 150 m, with a porosity of 15–32% and permeability of 10–1600 md. These fields are believed to be supported by a regional aquifer several thousand feet thick. Large seafloor subsidence has been observed in these reservoirs. Storage-Capacity Estimation Storage capacity...

The model can be used for quantitative seismic interpretation of reservoirs with variable net-to-gross and porosity away from well control...

... regimes relevant to the nanopore structure of the shale formation. The effect that compressible rock has on the porosity and apparent permeability changes with CH 4 production. CO 2 injection also is considered. The resulting model is composed of nonlinear partial differential equations that are solved...

.... In general, the matrix pore system does not significantly contribute to storativity or permeability. The effective porosity is approximately 4.2% on average. This value sometimes directs to the matrix porosity, but in this case study, high intensity of the microfracture presence behaves in a way similar...

... The estimation of volume of hydro-carbon in place (HIP) is a key formation-evaluation objective. In 1942, Gus Archie established the algorithm relating bulk resistivity ( R t ), porosity , formation water resistivity ( R w ), and water saturation ( S w ).
