JGC Corporation takes pleasure in announcing a successful award of a contract by SONATRACH of Algeria to construct gas boosting compressor stations for use at a natural gas processing plant now in operation in Hassi R'Mel.

The following is more information on this project:

1. Plant Owner
SONATRACH, a state-run hydrocarbons corporation of Algeria

2. Plant Location
Hassi R'Mel, Algeria Some 400 km south of Algier (the capital)

3. Contract:
Contract services: Design, procurement and construction services
Contractual form: Lump-sum, full turnkey contract

4. Contract Price
Approximately ¥40 billion

5. Delivery
First quarter of 2004

6. Key Information
In Hassi R'Mel, there are 5 natural gas processing plant modules completed and put into operation by the 1970s, which are Modules 0, I, II, III, and IV (of which II, III, and IV are installations built by JGC), constituting Algeria's largest gas producing site. Those modules are experiencing in recent years a fall in the wellhead pressure of feed gas because of long-time production. This project, designed to cope with such a lowered feed gas pressure over time, calls for the construction of boosting compressor stations upstream of the modules, so as to increase the pressure of the feed gas over the lowest operating pressure before sending it to the modules, to permit a continuation of stable operation.

These new boosting compressor stations are to be built in 3 different locations; south, north, and the center of the Hassi R'Mel site, corresponding to Module II, Module III, and Modules 0, I, and IV, respectively. Feed gas from wells is collected by gathering pipeline into several manifolds, from which it is sent to newly-built boosting compressor stations to be compressed and transferred to each module.

Each station is composed mainly of vapor/liquid separating drum, gas-turbine compressor, air-cooled gas cooler, and condensate pump. Auxiliary facilities include buildings such as instrument room and power unit room, utility facilities and fire-fighting systems.

Those stations' capacities and compressor numbers are:

• South: Approx. 62 million cubic meters/day 3 units
• North: 62 million cubic meters/day 3 units
• Central: 155 million cubic meters/day 5 units

7. Background
In Algeria, JGC is presently working on a crude oil recovery project in the Ourhoud oil field. As represented by this work, JGC's long-time involvement and extensive experience in this country, combined with its outstanding technological skills and cost competitiveness, have led to the award of the contract this time.

JGC is determined to make further efforts to come closer to the needs in Algeria.
