Petrophysical analysis of choti-01 well central Indus basin Pakistan (P-0904) (MFN 3901)

Abstract

The main purpose of the study is to evaluate hydrocarbon potential of a well named Choti-01, 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 all logs were correlated to mark the zone of interest i.e. reservoir zone. In our case the reservoir is lying in Sui Main Limestone. After the demarcation of reservoir (Sui Main Limestone), this zone was then divided into sub zones according to the quick look interpretation.These zones were evaluated for the hydrocarbon potential in detail using set of equations. The methodology adopted to accomplish this task includes; the measurements for the Shale volume by using Gamma Ray Log, Porosities by Sonic 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 Sui Main Limestone of Choti-01 well has considerable amount of hydrocarbon.
