Chevron to proceed with $4B Jansz-Io subsea compression project Chevron announced that its wholly owned subsidiary Chevron Australia Pty Ltd. (Chevron Australia) as operator and the Gorgon joint venture participants will proceed with the approximately $4-billion (AU$6 billion) Jansz-Io Compression (J-IC) project. Jansz-Io will be the first gas field outside Norway where the subsea compression technology comes to use. It is located around 200 kilometers off the Australian north-west coast at a water depth of approximately 1,350 meters (4,429 feet). The J-IC Project objective is to unlock low pressure reserves from the Jansz-Io reservoir and maintain plateau production rates to the Gorgon Project facilities on Barrow Island (BWI).
