KUWAIT - Oilfield Profile - Umm Gudair.

Umm Gudair, found in 1962, lies to the south of Minagish. The structural trend extends south across the boundary of the DZ. Production is from the Lower Cretaceous Minagish Oolite formation with 25 deg. API oil and 3.8% sulphur. It went on stream in 1962. Oil reserves were estimated at 4 bn barrels but the recovery factor is low. The Marrat formation lies beneath this field as well.

The field had a total of 33 wells in July 1990.

With the wells of Minagish having an average depth of 10,000 feet, those of Umm Gudair have a depth of 9,000 feet. Retreating Iraqi troops in February 1991 set the Minagish wells and some of Umm Gudair's ablaze, and toxic hydrogen sulphide released into the air made fire-fighting and repair work at the two fields extremely difficult.

Technip Geoproduction had started development work on Minagish and Umm Gudair before Iraq's invasion. Work included construction of oil and gas gathering facilities and a pipeline network at the two fields. Four of the GCs for Minagish and Umm Gudair were to be rebuilt totally according to Technip designs. After Kuwait's liberation, KOC and its contractors rehabilitated the field and had some of its installations rebuilt totally as in the case of Minagish. Umm Gudair's sustainable production capacity now is 100,000 b/d of heavy 22-26 deg. API oils.

One of the repaired GCs, GC-18, went into operation at these two fields in August 1994 with a capacity of 50,000 b/d. The four new GCs, to cost more than

$600m, should boost the two fields' capacity to 530,000 b/d. The four new GCs are: (1) GC-27 with a capacity of 190,000 b/d; GC-28, 220,000 b/d; GC-29 with a capacity of 40,000 b/d; and GC-30, 60,000 b/d.

The contract for GC-27 and 28, originally due to be awarded in July 1994 but delayed because of budget cuts by the government, was on Dec. 30, 1995 given to China Petroleum Engineering & Construction Corp. (CPECC). The Supreme Petroleum Council (SPC) chose the Chinese firm for political reasons and KOC got CPECC to lower its price to $390m, because Mitsubishi Heavy Industries had bid $391m. The completion date was set for November 1998. But CPECC has turned out to be far less efficient than thought. Its work is way behind schedule and would be completed in 1999. Parsons, in charge of KOC's projects, was opposed to the choice of CPECC but Kuwait had to please Beijing in view of their bilateral defence pact.

Minagish and Umm Gudair are to be developed by a foreign consortium under an IBBC. Their target capacity of 530,000 b/d before 2005 should become sustainable for up to 20-25 years, the duration of the IBBC. The foreign group should raise the recovery rate of the two fields' reserves, with KOC having estimated proven reserves at 3.3 bn barrels in Minagish and 3.2 bn barrels in Umm Gudair.
