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.
