The acoustic impedance (AI) differences between gas-sand and shale are very small in SLG gas field of Western China. Therefore the lithologic prediction solely by AI inversion will lead to multi-solution problem. Ni proposed a new elastic impedance (EI) calculation method (Ni, 2003) to deal with the seismic inversion and the prediction of lithology and fluid. In this paper, we compared this met...

Used initially in exploration, the dipmeter tool helped to locate and identify the major features of geologic structures that serve as oil traps. With improved techniques in data acquisition and computation, the application of this tool has expanded until it has become the principle logging measurement for describing internal lithologic features as well as revealing the sedimentological process...

Knowledge of reservoir distribution and quality in the offshore eastern Gulf of Mexico (EGOM) is essential for future economic development of hydrocarbon resources. The Norphlet Fm. has been a significant hydrocarbon reservoir in the onshore EGOM region since the late 1960’s; however, due to sparse lithologic data in the offshore EGOM, predicting Norphlet Fm. reservoir distribution in this area...
