The field�in 140 m of water, 120 km northwest of Dampier, Australia, and 23 km southwest of the Goodwyn Alpha platform�will be developed via subsea facilities. The scheme calls for two subsea production wells to be tied back to Goodwyn Alpha via a 12-in. pipeline.

Production will be commingled with production on the Goodwyn platform, processed, and exported to shore in an existing trunkline.

The North West Shelf venture partners have given final investment approval for the development, says operator Woodside, and the state and commonwealth governments have okayed the development concept. Approval of the final field development plan is expected soon, says Woodside. Environmental approval under the Environment Protection and Biodiversity Conservation Act "is being progressed," said the company.

Echo-Yodel is expected to produce 37 million bbl of condensate and 4 tcf of gas over its 4-5-year life span. Slated to begin in 2002, Echo-Yodel production will help compensate for the natural decline in condensate output from the much larger Goodwyn field, said Woodside.

The project is in the detailed design and procurement phase. Contracts have been awarded for the supply of the subsea control system and subsea christmas trees. The contract for installation of the subsea riser and tie-in of the subsea facilities is being evaluated and will be awarded in early October, said the firm. Modification work on Goodwyn Alpha for tie-ins to processing equipment was completed this month during a planned shutdown.

Equal partners in the North West Shelf Venture are: Woodside, BHP Petroleum (North West Shelf) Pty. Ltd., BP Developments Australia Pty. Ltd., Chevron Australia Pty. Ltd., Japan Australia LNG (MIMI) Pty. Ltd., and Shell Development (Australia) Pty. Ltd.
