Electro-Facies Analysis of Reservior Rocks of Krishna-Godavari Basin

Recent advances in electric logs make it possible to record the logs at very thin sampling interval. The natural radiation of rocks (gamma rays) can be analysed while recording itself into three basic components like K⁴⁰, Th²³², and U²³⁸. The electro-facies analysis can be used to interpret the nature of sedimentary environments. The interpretation techniques for identifying the nature of different sedimentary environents arc discussed with suitable examples of electric logs from Krishna-Godavari basin. Fracture identification procedure in case of basalts and extension direction of Paleogene reservoir sands are discussed. NGS ratio log can be used in identifying the debalable age boundaries.
