Significant discoveries of heavy oil accumulations (7+ billion barrels STOIIP) in South Oman have led to a greater emphasis on their development in the last 3-4 years. These fields are now being developed. Most of the reserves occur in glacial to periglacial sandstones of Permo-carboniferous age which exhibit rapid facies variations. The high viscosity of the crude and unconsolidated nature of the formations create a typical sand production problem environment. The occurrence of H/sub 2/S in some fields and anticipation of early water production from both edge and bottom aquifers has necessitated cautious planning of facilities. Beam pumping is being installed in all fields. Most fields are planned for development on a square-grid pattern with varied well spacing which considers crude characteristics, reservoir properties and future EOR possibilities. Since primary recoveries are expected to be low (5 to 15 percent), steps are being taken to initiate a pilot polymer flood and, at least, one pilot steam flood. Steam soak is also considered possible for the more viscous (greater than or equal to 1000 cP) reservoirs. Necessary basic reservoir data are being gathered for these projects and reservoir simulation process design studies are in progress. Facilities design and installation is also underway.
