Exploration drilling since 1994 has resulted in six new Egyptian field discoveries, four of which are currently producing approximately 40,000 BOPD. Primary production is from the Cretaceous Bahariya and Kharita sandstone reservoirs, as is typical in the Watern Desert. The area is fast becoming the newest and largest Previous HitoilNext Hit producing province. The Qarun Field is emerging as the largest and most prolific Previous HitoilNext Hit field in the Western Desert.

Qarun Field lies on the southeast flank of the Kattaniya uplift and the northwest flank of the Cenozoic Gindi Basin 80 km southwest of Cairo. The Kattaniya uplift is an inverted Mesozoic basin containing thick Middle Jurassic Khatatba Previous HitoilNext Hit-prone Previous HitsourceNext Hit rocks. The Previous HitoilNext Hit migrated southeastward to charge Qarun field along a NE-SW trending intrabasinal paleo arch, separating the Kattaniya inverted basin from the Gindi basin.

The Qarun and Beni Suef Previous HitoilNext Hit discoveries lie just south of Cairo, adjacent to the Nile River, within the Qarun and East Beni Suef concessions, in a readily accessible area. The region has been previously explored by Shell, Amoco, Esso, and Braspetro. Seagull Previous HitEnergyNext Hit International and Apache Corporation are currently exploring in conjunction with the Egyptian General Petroleum Corporation (EGPC).

Qarun Field (A lobe) was discovered in October 1994 by Phoenix Resources Company with partners Apache Corporation and Global Natural Resources (now Seagull Previous HitEnergyNext Hit). The drilling of the El-Sagha 1-A wildcat encountered Previous HitoilNext Hit pay in both Cenomanian Bahariya and Albian Kharita Sandstones. The updip El-Sagha 3- X confirmation well encountered over 285 feet of net Previous HitoilNext Hit pay in the Bahariya and Kharita sands in a continuous gross Previous HitoilNext Hit column over 500 feet thick. The well tested at an aggregate rate of 11,957 BOPD of 42° gravity Previous HitoilNext Hit. Primary reservoirs are found at depths between 8700 and 9400 feet. The Qarun Previous HitoilNext Hit field complex (A, B, and C lobes) consists of two en echelon compressional folds trending northeast and southwest established along the upthrust sides of two faults.

During September 1996, the C-1X well opened up Qarun Southwest Field (C lobe), logging 275 feet of net Previous HitoilNext Hit sand in the Bahariya and Kharita formations. The well tested at a combined rate of 4600 BOPD. Also during that month, the Wadi Rayan 1- X wildcat, situated 55 km south of Qarun field on the south flank of the Gindi Basin, tested 950 BOPD of 25° gravity Previous HitoilNext Hit from Cenomanian Abu Roash "G" sandstones at 5500 feet. This discovery opens up a new exploration trend in the southern portion of the Qarun concession.

Farther south, 75 km from Qarun field, within the adjacent East Beni Suef concession, the Beni Suef- 1-X wildcat tested 40° gravity Previous HitoilNext Hit from the Bahariya and Kharita formations at a depth of approximately 7000 feet at an rare of 6976 BOPD during September 1997. This well, operated by Seagull Previous HitEnergyNext Hit International with partner Apache Corporation, confirms a new productive basin that seismic data indicate extends eastward across the Nile River.
