The Awali field is located in the central part of the main Bahrain Island. The field is an asymmetrical anticline trending NS with multiple stacked carbonate and clastic reservoirs cut by an extremely complex faulting system. The field has been producing since 1932 and contains 16 oil-producing and 6 gas-producing reservoir zones. Awali field has a complex production history and is in a mature state with a gas-injection scheme that has been in operation for many decades. The field requires close monitoring while history-matching is a challenging effort. In order to monitor the changes in subsurface and surface logistics efficiently, a 4-D GIS technology was implemented for the field. It yielded cost-savings and an easy procedure to follow. In addition to the petroleum engineering tools, like reservoir simulation and management studies, the 4-D GIS technology readily helped in tracing the injected fluid (gas and water) chronologically. This has not only helped time management but also the evaluation of reservoir performance. This presentation highlights the impact of the GIS technology, which will be very useful for other oil companies in the region to implement.
