Atchafalaya Bay gas-condensate field due larger pipeline

Operations have begun to install a pipeline that will enable a large increase in production from Marathon gas-condensate field in Atchafalaya Bay off Louisiana, said Petsec Energy Ltd., Sydney.

The $3 million pipeline, to be installed by early third quarter 2012, is to increase the field’s production capacity to 50-60 MMcfd. The field operates profitably at present gas prices and the current restricted rate of production, Petsec Energy said.

A group led by private Phoenix Exploration Co. has drilled two wells that are capable of delivering as much as a combined 50 MMcfd. A third well, in 8 ft of water on State Lease 20221, is at 14,700 ft enroute to 19,000 ft.

Private companies have 43.25% working interest in the field, and Apache Corp. has 48.75%. Petsec Energy has 8% interest in the wells and pipeline.
