Abstract: We consider the fracture modeling on the base of stress inversion model, as a tool for detecting discontinuities in Jeribe/U. Dhiban carbonate reservoir and, consequently, determining prospective areas for drilling wells at Sarqala field, North of Iraq. This method works on the stress heterogeneity caused by the activation of the main faults, and is formalized using the boundary element method in Petrel software

Abstract: The article briefly reviews the features of Bukharo-Khiva region resources analysis, the methodology used and the results achieved. The geological concept of this region based on the available geological, geophysical as well as statistical data was reviewed. For that purpose 2 base methodologies were applied: discovered and undiscovered oil and gas accumulations distribution according to the reserves volumes [6] and functional relation of the discovered accumulations distribution according to their reserves volumes [4]. The first methodology allowed calculation of the expected accumulations amount and their resources volumes in Bukharo-Khiva region, while the second one provided us with their more precise approximate volumes in 4 different oil and gas accumulation areas with reference to different plays. On the basis of the available data the expected fluid types and probable accumulations localization forecast was conducted as well.
