Abstract
The Western Desert forms the most extensive geographic division of Egypt. It covers 700,000 square Kilometers or more than two thirds of the whole area of Egypt. It extends 1000 kilometers from the Mediterranean shoreline in the north to Sudanese border and 600-800 kilometers from the Nile Valley in the east to the Libyan border to the west (EGPC, 1992). Geomorphologically, it consists of large plateau of stone desert with numerous large and deep closed topographic depressions. Exploration activities started in this area by the end of 1963 when Philips Petroleum Company (PPCO) has signed an exploration agreement with the Egyptian General Petroleum Corporation (EGPC).The first commercial oil discovery in the Western Desert was the Alamein Field. In 1963, Phillips Petroleum Company announced the production of 8000 BOPD of 34.5° API from the Aptian Alamein Dolomite Reservoir. During the drilling of the Alamein development wells, oil and gas shows were consistently noticed in the Abu Roash “G” Dolomite, Middle Bahariya and Razzak Sands Reservoirs which started to produce oil in 1966. In 1967, the Western Desert Operating Petroleum Company (WEPCO) was formed as a joint venture operating company between PPCO and EGPC to carry out further exploration activities and develop Alamein Field.
Yidma Field was the second field which discovered by WEPCO in July 1971, it lies only 6 Kilometers southwest of Alamein Field. Ten wells were drilled to develop Yidma Field, seven of which are oil producing from the Alamein Dolomite main reservoir.
