Computing of petrophysical properties for dolomite and quartzite reservoir formations
Petrophysical properties remain very important to the oil and gas industry; from quantification of hydrocarbon reserves and developmental strategies to time decision making for reservoir navigation. Among the main objects of petrophysical properties is determining whether the rock formation is a potential oil or/and gas reservoir or not. Environmentally, shale and lithology corrections conducted to raw data of neutron porosity log, bulk density log, and gamma ray borehole correction, in order to calculate the total corrected porosity, and estimating oil initial in place. This study aims to determine porosity, net pay thickness, shale content, and fluid saturation of two different formations in the same reservoir. On the basis of petropysical data, sediments of dolomite and quartzite formations were found to have effective porosities of 11.8% and 7.8%, respectively. Hydrocarbon saturation between 21.9 to 48% for dolomite formation, and 22 to 63% for quartzite formation.
