![]() The under-saturated reservoir contains light oil, with low viscosity (API gravity of 35°)ĭue to inadequate aquifer support a full water injection scheme at matrix condition was implemented 10 years after natural depletion with multilateral horizontal water injectors drilled about 30m below the producers. The reservoir is thick with relatively thin oil column heights of typically 5 to 30m and low permeability. ![]() The tight reservoir is situated in a gently dipping, fault bounded matrix carbonate in North Oman. These include analytical tools, diagnostic methods, tracer surveys and downhole temperature monitoring which lead to the implementation of cyclic production methodology. Systematic surveillance and reservoir management tools are used to analyze the fracture initiation, impact on production and reserves performance and predict the future behavior of the field. This paper describes the principles of cyclic production implemented in a matured water flood field to manage the occurrences of short circuit in a pattern.
