This analysis covers the WD9, WD30, WD33 and Razzak blocks in the Western Desert. The key developments on the blocks include the Abu Gharadig, Razzak and Wadi fields. Oil production is processed at each field and exported via the El Hamra terminal as part of the Western Desert blend. Apache became operator of the blocks in July 2010, when it acquired BP's entire Western Desert portfolio as part of a wider deal. In recent years, Apache has been very successful in redeveloping the fields and has carried out simulation studies to improve its understanding of the reservoirs. New developments have been tied in very quickly, in some cases within months of first discovery, by utilising the exploration well and existing infrastructure. Despite Apache's success with the fields to date, Abu Gharadig and Razzak which underpin the majority of the area's production, are maturing and arresting the areas decline will be increasingly reliant on new exploration.
