Abstract

The present study deals with the petrophysical evaluation using well log data of Lower Goru Formation from five selected wells namely Nara-1, Kadanwari-3, Kadanwari-4, Gajwaro-1 and Mehrab-1 in the Lower Indus Basin. Various cross plots indicate that the formation of interest is mainly composed of sandstone, shale and carbonates. In addition, clay content is also analysed using potassium versus thorium and PEF versus Th/K ratio plots. Interactive Petrophysics (IP-2013) software is used to assess the petrophysical parameters. The volume of shale has been estimated between 6.1% and 14.07% from the studied wells. Similarly, the total porosity is observed between 14.6% and 18.02% while the effective porosity ranges 12.5–16.5%. The water saturation is quite low and exhibits between 14.05% and 31.58%. Moreover, the hydrocarbon saturation ranges 68.42–85.95% in the studied wells. 23 pay zones of variable thickness and significant hydrocarbons presence have been identified within the studied wells, thus proving the Lower Goru Formation as a promising reservoir. The study also indicates Nara-1 Well as the most prolific in terms of high hydrocarbon saturation and low water saturation. The study method can be used within the vicinity of Lower Indus Basin and similar basin elsewhere in the globe to quantify petrophysical properties of oil and gas wells and comprehend the reservoir potential.
