AbstractThis paper presents a successful integration of sparsely distributed permeability data including core-derived permeability and welltest-derived permeability into a viable geocellular model of 3.96 million cells for a giant carbonate reservoir.The resulting model required minimum permeability modification to achieve a 40-year history match. Fracture intensity trend was derived by carefully comparing the curvature of the structure, detailed matrix permeability, and welltest-derived permeability. This approach, although intuitive, allows for a better and realistic characterization of this large reservoir in the absence of seismic and other fracture identification tools like image logs while preserving vertical and lateral variation in permeability. Moreover, the paper presents statistical analysis of core-derived permeability illustrating lateral variation of permeability distribution.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
