Petrophysical analysis of Miano-05 well central Indus basin Pakistan (P-0899) (MFN 3905)

Abstract

The main objective of the Petrophysical Analysis was to evaluate hydrocarbon potential of Miano Well # 05, Central Indus Basin, Pakistan. The purpose has been achieved by utilizing complete suite of wire line logs and the available well data. This complete set of data had been 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 horizon of interest i.e. reservoir zone. In our case the reservoir existed in Lower Goru Formation of the Cretaceous age. After the demarcation of reservoir zone this zone was evaluated for the hydrocarbon potential in detail using set of equations and different formation evaluation charts made by Schlumberger. The methodology adopted to accomplish the task included following measurements in the reservoir zone of Miano Well # 5; measurement of Shale volume by employing Gamma Ray Log, estimation of Porosity using Density and Neutron Log, estimation of Effective Porosity, calculation of Resistivity of water utilizing Spontaneous potential log, evaluation of saturation of water and hydrocarbon saturation using Archie equation and evaluation of permeability. The final results for the dissertation have been displayed in the form of excel sheets and graphs for a better approach towards the task. All of the displayed results show a good reservoir quality.
