The Design of the First Miscible Sour Gasflood Project in Oman

This paper summarizes parts of the strategies that were<br>developed to demonstrate the feasibility of the first miscible<br>sour gas injection project in one of the reservoirs of a cluster<br>of fields in southern Oman. The hydrocarbons in the cluster<br>are contained in carbonate “stringers”, which are<br>approximately 100m thick slabs of carbonate floating within<br>salt at depths between 2.5 km to 5 km. Large quantities of sour<br>gas with 3-4% H2S and 10-15% CO2 are available to be used<br>as miscible agents.
