Discoveries, Western Desert, EgyptBy

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
oil
producing
province. The Qarun Field is emerging as
the largest and most prolific
oil
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
oil
-prone
source
rocks. The
oil
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
oil
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
Energy
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
Energy
). The drilling of the
El-Sagha 1-A wildcat encountered
oil
pay
in both Cenomanian Bahariya and Albian
Kharita Sandstones. The updip El-Sagha 3-
X confirmation well encountered over 285
feet of net
oil
pay in the Bahariya and
Kharita sands in a continuous gross
oil
column over 500 feet thick. The well tested
at an aggregate rate of 11,957 BOPD of
42° gravity
oil
. Primary reservoirs are
found at depths between 8700 and 9400
feet. The Qarun
oil
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
oil
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
oil
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
oil
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
Energy
International with partner Apache
Corporation, confirms a new productive
basin that seismic data indicate extends
eastward across the Nile River.
