oa Structural Controls on the Development of Sweet Spots in Tight Reservoirs

Reservoir sweet spots represent areas of improved permeability in tight reservoirs. Sweet spots are considered critical exploration targets to maximize productivity in deep tight reservoirs. Historically the process of identifying sweet spots from direct or indirect indicators relied mainly on seismic data analysis. This study presents concepts for development of three major types of sweet spots in tight reservoirs relied mainly on structural concepts: the structural-stratigraphic sweet spots; and the structural-digenetic sweet spots, based on the geologic processes involved in their generation. Integration of gravity, magnetic, seismic and outcrop data in the eastern Arabia province, with concepts of strain analysis are the basis of this study. Exploring for combined sweet spots is an economic demand of higher priority but it requires integration and much detailed analysis, using multi-data.
