Prospect Generation & Evaluation of Nur Area, Sindh, Lower Indus Basin, Pakistan

Abstract

This study presents an integrated geological, geophysical, and petrophysical evaluation of the Sujawal Block in the Lower Indus Basin, Pakistan, with a focus on the NUR-01 Well. Using 2D seismic data interpreted in Kingdom™ Software, major subsurface horizons such as the Top Lower Goru and Chiltan Formation were mapped. Structural features, including fault-bounded closures were identified, indicating potential hydrocarbon traps. Petrophysical analysis, conducted via Geographix™ and PRIZM, assessed the Lower Goru Sands (Zones A and B) using LAS log data. Parameters such as VSh, PHIE, and Net Pay indicated moderate reservoir quality with hydrocarbon-bearing potential. A synthetic seismogram was generated to enhance the tie between seismic reflectors and well tops, improving interpretation confidence. Correlation of seismic and petrophysical data confirmed two viable leads, with the primary lead already tested by NUR-01. The secondary lead remains undrilled and less certain due to limited well control. Overall, the tectonic setting, reservoir stratigraphy, and interpreted structures suggest strong hydrocarbon prospectivity in this underexplored area.
