Petrophysical Analysis of Sarai Sidhu-1 Well of Central Indus Basin Using Wireline Logs (P-0886) (MFN 3237)

Abstract

The main purpose of the study is to evaluate hydrocarbon potential of a well named Sarai Sidhu-1, Punjab Platform, Central Indus Basin, Pakistan. This has been achieved by using complete suite of wire line logs and available well data. This complete set of data is issued by Land Mark Resources, Pakistan with the prior permission of Directorate General of Petroleum Concessions, Pakistan. To complete the above mentioned task the all logs were correlated to mark the Formation tops. These Formations were evaluated for the hydrocarbon potential in detail using set of equations. From this analysis we came to know that Ghazij Sui Member and Lumshiwal Formation are acting as reservoirs. The methodology adopted to accomplish this task includes; the measurements for the Shale volume by using Gamma Ray Log, Porosities by Density &Neutron Log, Resistivity of water by using Rwa method, Saturation of water in the zone of reservoir and Hydrocarbon saturation using Archie equation. The results for the dissertation were then displayed in the form of excel sheets and graphs for the better approach towards the task. These all displayed results show that the Sarai Sidhu-1 is mostly water bearing and Lumshiwal Formation and Ghazij Sui member are well producing reservoirs.
