Petrophysical Analysis of Well Sher-01, Lower Indus Basin, Pakistan

Abstract

The main purpose of this study is to evaluate the hydrocarbon potential using well log data of Sher-01, Thatta, Southern Indus basin, Pakistan. The above-mentioned well was first exploratory but now it is abandoned. Porosity and resistivity logs do not show any direct identification for the presence of hydrocarbons. We have marked two zones in the Lower Guru formation, zone I is from 5570 feet to 5700 feet in depth and zone 2 is from 6300 feet to 6500 feet in depth. Various petrophysical properties like porosity, resistivity, volume of shale and fluid saturation have been calculated through different logs. Although both the zones have clean lithologies with very little shaly content and good effective porosity but the graphs of effective porosity and the hydrocarbon potential of zone 2 show very high value as compared to zone 1, by which it has been said that zone 2 is more efficient in hydrocarbon as compared to zone 1. By studying all these aspects we came to know that Sher-01 well is oil prone well.
