Mr Christopher Oliver
Chevron Australia Pty Ltd (CAPL) is the operator for the Gorgon Gas Development (also known as the Gorgon Project) on behalf of the Gorgon Joint Venture. Offshore production wells and pipeline infrastructure associated with the Jansz–Io and Gorgon gas fields gather and transport gas to the Gorgon Gas Treatment Plant on Barrow Island, Western Australia (WA), where it is processed.
Compression facilities are expected to be installed to support the future recovery of hydrocarbons from the Jansz–Io gas field once the pressure in the reservoir is depleted and is insufficient to sustain peak production rates. Compression facilities will enable efficient recovery of hydrocarbons within the Jansz–Io gas field, and from other gas reserves in the Greater Gorgon area.
The proposed geophysical and geotechnical surveys will be used as a basis for the engineering design of the compression facility location, mooring locations, and flowline routes. The surveys will also include potential future flowline routes from adjacent backfill fields to the Jansz–Io compression facility.
