BHP Billiton to Develop Zamzama Field

BHP Billiton has received approval for the development of the Zamzama gas field in southern Pakistan. The announcement follows the signing of separate Gas Sales and Purchase Agreements and a Gas Pricing Agreement with the Government of Pakistan, the Sui Southern Gas Company Limited and Sui Northern Gas Pipelines Limited.

The agreements cover the supply of up to 320 million standard cubic feet per day (MMcf/d) of gas over the expected field life of 20 years, commencing in 2003. The core area of the Zamzama field to be developed has estimated proven and probable gross reserves of 1.7 trillion cubic feet (Tcf), of which BHP Billiton's equity share is around 650 billion cubic feet (Bcf).

The Zamzama development will commercialize gas resources from the field that were initially produced via an extended well test (EWT) production facility. Capital expenditure for this phase of the project will be in the order of US$100 million (BHP Billiton share US$40 million).

First production from the EWT commenced in March 2001, and at present the field is producing up to 100 MMcf/d of gas, which is being supplied to the Sui Southern Gas Company Limited under a 21-month contract.

President and CEO BHP Billiton Petroleum Philip Aiken said the successful technical and commercial operation of the EWT was an important precursor to the development of the field reserves.

"The success of the EWT has provided the impetus to develop further what is a key asset in BHP Billiton's gas commercialisation strategy," he said.

"The expansion of the Zamzama field will provide long-term benefits to all stakeholders and also will enable BHP Billiton to continue its positive association with the people and Government of Pakistan."

The Zamzama field development will require two additional processing trains which will be located on the existing EWT plant site, and the drilling of a minimum of three development wells. A stabilized condensate flow of 2,000 barrels per day will be exported by a small diameter pipeline to nearby pipeline infrastructure.

The Zamzama field lies within the original Dadu Exploration Concession awarded to BHP Billiton Petroleum in February 1995, located in the Sindh Province of southern Pakistan (approximately 200 kilometers north east of Karachi). The field is a major resource, covering an area of about 120 square kilometers, and ranks fourth in terms of Pakistan's discovered gas reserves.

BHP Petroleum (Pakistan) Pty Ltd has a 47.5 percent interest in the Zamzama field, with partners LASMO (MP) Ltd (a wholly owned subsidiary of Eni S.p.A) - 23.75 percent, PKP Exploration Ltd (formerly Premier Exploration Pakistan Ltd) - 23.75 percent and Government Holdings (Private) Ltd - five percent.

Government Holdings has the right to acquire an additional 20 percent equity, following which revised interests would be: BHP Billiton - 38.5 percent, Government Holdings - 25 percent; PKP Exploration - 18.75 percent and LASMO - 17.75 percent.
