APPRAISAL & DEVELOPMENTThe Sfax Offshore Permit is located in the Pelagian Basin in the northern portion of the Gulf of Gabes, southeast of the city of Sfax and just south of the Kerkennah Islands. The Permit contains 3 oil discoveries known as Salloum, Jawhara and Ras El Besh. Ashtart Field (350 MMBO Estimated Ultimate Recovery) lies just off the southeastern boundary of the Permit. Water depths within the permit range from sea level to a maximum of approximately 80 meters.![]() The El Garia nummulitic limestone has also been proven productive within the Sfax Offshore Permit. In 1995, ARCO drilled the Ras El Besh Well #1 (REB1) which had hydrocarbon shows in the El Garia but was not tested. In 1997, ARCO drilled the Ras El Besh Well #2 (REB2) which tested 612 BOPD in the El Garia. In general, the reservoir characteristics of the El Garia include well log and core porosities that range from 12 percent to 25 percent with corresponding core permeabilities that range from < 1 md to over 500 md. The Upper Senonian Abiod fractured chalky limestones, as well as the Coniacian Douleb and Turonian Bireno bioclastic and oolitic carbonates are prolific gas producing reservoirs further to the east of Ashtart Field in the Miskar (gas) Field. The Miskar Field (discovered in 1974 by Serept) is estimated to contain a minimum reserve of 3 TCF of gas and gas equivalent condensate. This reservoir is also productive from four smaller oil fields in the Sfax area onshore. These include Gremda, Guebiba, Mahares and Rhemoura Fields, which have a combined current estimated ultimate recovery of 22 MMBO. ![]() |
