Petrophysical Analysis of Meyal Well 9P, Upper Indus Basin, Pakistan (P-0888) (MFN 4858)

Abstract

Meyal field is present in district Attock and more specifically close to PindiGheb. It is situated 110 km southwest of Federal Capital Islamabad and is bounded by latitudes 33o17′34′′ N and longitudes 72o06′03′′ E. Meyal-9P well is part of the Meyal block which lies in the central part of Potwar plateau of Upper Indus basin. The Kalachitta-Margalla Ranges are in the north and the Salt Range is in the south. The Indus River and the Jhelum/Soan rivers are passing on its western and eastern sides respectively. A number of active surface as well as subsurface structural features dominates this part of Potwar plateau. The data provided to us included well tops and well logs of Meyal-9P. This was acquired from LMKR Islamabad with the prior approval from the Directorate General of Petroleum Concession (DGPC). The main purpose is to observe and evaluate the petrophysical characteristics of the well. Petrophysical analysis of well Meyal-9P included marking the reservoir zones (pay zones) and carrying out log interpretation. Values of volume of shale, density and neutron porosity as well as those obtained from resistivity logs are marked. Water resistivity and saturation of water and hydrocarbon are also calculated. Results claim that there is one hydrocarbon saturated formation present in Meyal-9P, which is the limestone present in the Sakesar Formation. It is also noted that Sakesar has a bigger contribution as reservoir on the basis of porosity calculation. Sakesar Formation is our zone of interest as a reservoir due to limestone secondary porosity.
