Unveiling the subsurface lithologic attributes of Pirkoh-1 and Pirkoh-3 area by using petrophysic (T-1375) (MFN 3659)

Abstract

The current study deals with petrophysical studies of wireline logs of well, Pirkoh 01 and Pirkoh 03 located in the Pirkoh area of Central Indus Basin, Balochistan. Main purpose of this thesis is to understand the hydrocarbon potential of Pirkoh 01 and Pirkoh 03 involving well logs interpretation using composite log suite that include Resistivity, NPHI (Neutron porosity), Gamma ray, acquired from Directorate General of Petroleum Concession of Pakistan (DGPC). Average shale volume of Pab Sandstone of Pirkoh 01 is 65%, total porosity is 13.15% and water saturation is 56% while Pirkoh 03 has average shale volume 49%, effective porosity ranges from 0-40% in Pab sandstone and water saturation is 59%. Petrophysical interpretations show the Pab Sandstone of Pirkoh 01 and Pirkoh 03 is gas bearing.
