A large scale steamflood pilot test has been underway since 2008 in the first Eocene reservoir in the Wafra Field in the Partitioned Zone (PZ) between Saudi Arabia and Kuwait. The first Eocene is a carbonate reservoir and it is the shallowest reservoir in the Wafra Field with an average depth of 1,000 feet The primary objective of the pilot is to reduce technical and economic risk/uncertainty to determine whether full field steamflood development is feasible.

The pilot consists of sixteen 2.5 acre inverted 5 spot patterns with associated steamflood and production facilities. The injection interval is the 1st Eocene "C" interval at a depth of 1300 ft. This is the first multi-pattern steamflood of a carbonate reservoir in the Middle East.

This presentation will share the early results from the implementation of the pilot project. The production response to carbonate steamflooding will be shown along with examples of individual well production behavior. Early insights into carbonate steamflood response, variability of production response by pattern and the identification of operating issues associated with carbonate steamflooding will be shared.

The success of the pilot test project has huge implications to not only the PZ, but to the entire Middle East region due to the vast amount of oil contained in reservoirs that would be considered targets for the steamflood process.

Conclusions and lessons learned that can be drawn from carbonate steamflooding results to date in the pilot will also be shared in the presentation
