Abstract
The present study is aimed at evaluating the reservoir potentials of South Tapti Basin of India with limitation to the available data. A number of petrophysical parameters, i.e., effective porosity (Φ), water saturation (Sw), formation water resistivity (Rw), hydrocarbon saturation (So), and true resistivity (Rt), are evaluated using the well log data, and the reservoir characterization is performed. The analysis shows a hydrocarbon-bearing zone in between 1866 and 1874 m, which contains gamma ray (GR) value of 34.4 API, resistivity of 117.3 Ω m, and average porosity of 35.7%. To know the fluid type in the reservoir zone, neutron porosity and density porosity are plotted together and a crossover has been noticed at 1866–1874 m depth which indicates that the reservoir is filled with gas. The analysis of petrophysical parameters and cross-plots shows that the reservoir is filled with sandstone with some clay content separated by shale markers, which act as seal rock for the reservoir.
