Petrophysical analysis of Miano-02 well, Central Indus basin Pakistan (P-0881) (MFN 3248)

Abstract

The main objective of the study area was to understand the geological setting and perform the petrophysical analysis to evaluate hydrocarbon potential of Miano-02 well. The project was initiated by taking into account the exploration history of the area followed by comprehension of stratigraphy and tectonic settings. We established the petroleum system, evaluated the source rock maturity and performed the petrophysical analysis. 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, source rock maturity was calculated utilizing Lopatin’s burial history plot method. All the reservoir intervals were evaluated for the hydrocarbon potential in detail using set of equations and different formation evaluation charts made by Schlumberger. Lower Goru B-sand is the producing reservoir of Miano Field. The primary target of the Maino-02 well being drilled was A-sands of Lower Goru Formation belonging to Lower Cretaceous age while secondary target had been B-Sands of Lower Goru of the same age. The methodology adopted to accomplish the petrophysical interpretation of Miano-02 well included 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. 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
