Petrophysical analysis of Meyal 06P, upper Indus basin, Pakistan (P-0898) (MFN 3906)

Abstract

Meyal field is present in district Attock and more specifically close to PindiGheb. It issituated 110 km southwestof Federal Capital Islamabad and is bounded by latitudes 33o11′-33o22′ N and longitudes 71o59′-72o18′ E. Meyal-06P 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-06P. This was acquired from Bahria University, Islamabad with the prior approval from the Directorate General of Petroleum Concession (DGPC). The main purpose was to observe and evaluate the petrophysical characteristics of the well.Petrophysical analysis of well Meyal-06P 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 are two pay zones present in Meyal-06P. These are the limestone present in the Chorgali and Sakesar formation. It is also noted that Chorgali has a bigger contribution as reservoir.
