Petrophysical analysis of Qadirpur-14&15 wells, central Indus basin Pakistan (P-0873) (MFN 3279)

Abstract

The main objective of the study area is to know about the geological setting and perform the petrophysical analysis to evaluate hydrocarbon potential of Qadirpur-14&15 wells. The project was initiated by taking into account the exploration history of the area followed by comprehension of stratigraphy and tectonic settings. We established the petroleum system, evaluated the source rock maturity and performed the petrophysical and rock mechanics analysis. The purpose has been achieved by utilizing complete suite of wire line logs and the available well data. This complete set of data was issued by Land Mark Resources, Pakistan with the prior permission of Directorate General of Petroleum Concessions, Pakistan. To complete the above mentioned task, source rock maturity is calculated utilizing Lopatin’s burial history plot method. All the reservoir zones are evaluated for the hydrocarbon potential in detail using set of equations and different formation evaluation charts made by Schlumberger. Sui Main Limestone is the producing reservoir of Qadirpur Field. The methodology adopted to accomplish the petrophysical interpretation of Qadirpur-14&15 wells included measurement of shale volume by employing gamma ray log, estimation of porosity using density and neutron log, estimation of effective porosity, calculation of resistivity of water utilizing spontaneous potential log, evaluation of saturation of water and hydrocarbon saturation using Archie equation.
