Activity Description

Chevron Australia Pty Ltd (CAPL) Gorgon Liquefied Natural Gas (LNG) assets (Gorgon Project) produce hydrocarbon fluids from offshore fields (Gorgon and Jansz), transport these fluids through subsea flowlines and are processed on, and exported from an LNG facility located on Barrow Island off the coast of Western Australia. Activities described in this EP include the operational Gorgon and Jansz production wells. A total of 29 wells (15 Gorgon, 14 Jansz) have been drilled and completed, across two drilling campaigns, within the Gorgon and Jansz fields. 18 wells (8 Gorgon, 10 Jansz) were constructed as part of the Gorgon Foundation Project (GFP) campaign (2012-2014), and a further 11 wells (7 Gorgon, 4 Jansz) were constructed during the Gorgon Stage 2 (GS2) campaign (2019-2020). CAPL has developed this Environment Plan (EP) to manage the environmental impacts and risks for well intervention and maintenance of the operational Gorgon and Jansz production wells. This EP has been prepared in accordance with the requirements of the Commonwealth Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGS Act) and Offshore Petroleum and Greenhouse Gas Storage (Environment) Regulations 2023 (OPGGS(E)R) as administered and for regulatory acceptance by the National Offshore Petroleum Safety and Environment Management Authority (NOPSEMA). Activities described in this EP (which include the operational Gorgon and Jansz production wells) are located within production licenses WA-37-L and WA-38-L ~130 km off the north-west coast of Western Australia (WA), and ~65 km northwest of Barrow Island. The Jansz gas fields are located within production licences WA-36-L, WA-39-L and WA-40-L ~200 km off the north-west coast of WA in water depths of ~1,350 m.
