WebDec 13, 2024 · Density and neutron-density methods were used to calculate total and effective porosities. Thomas and Stieber ( 1975) method was used to determine shale distributions, sand fractions, and sand porosity. This method was selected to account for the thin-bed effects on the log measurements in the thin turbidite sands. WebJun 27, 2024 · Total porosity calculation By the combination of neutron–density logs, the total porosity within reservoirs interval was determined. The equation to compute the total porosity from neutron and density logs that may be expressed as: \varPhi_ { {\text {tot}}} = (\varPhi_ {\text {N}} + \varPhi_ {\text {D}} )/2 (3)
