Petrophysical Analysis of Miano-09 Well, Lower Indus Basin, Pakistan

Abstract

The objective of this study is to determine the hydrocarbon potential in Miano-09 well using wireline logs. Miano Gas field is located in the Thar Desert, in the Sukkur region. Log data used in this study includes the Gamma-ray log, Gamma-ray Neutron tool, Resistivity log, Caliper log, and SP log. The borehole profile of the zone of interest was good. The calculation of the porosity was carried out with the help of the Gamma- ray Neutron Tool. One prospect zone had been marked within B interval. The present study showed that the volume of clean was about 90.56%. The total porosity of the zone of interest was 3.12% while effective porosity was 12.02%. Saturation of water was 41.37% which showed that the zone of interest is a hydrocarbon-bearing zone as compared to water. Petrophysical analysis showed that prospect zone has clean lithology and good effective porosity. Besides clean lithology and good effective porosity there is relatively high percentage of hydrocarbon saturation. Therefore, petrophysical analysis reveals that in Miano-09, B-interval of Lower goru formation is acting as an effective reservoir.
