Xena

Location

The Xena gas field is located offshore North West Australia, specifically in the Northern Carnarvon Basin, approximately 190 km north-west of Karratha.

Project Overview

The Xena field is part of the broader Pluto LNG project, which is operated by Woodside Energy. The Pluto LNG project processes gas from both the Pluto and Xena fields.

Ownership and Partnerships

The Pluto LNG project, which includes the Xena field, is a joint venture between Woodside Energy (90% interest) and Japanese companies Tokyo Gas and Kansai Electric, each holding a 5% interest.

Development and Operations

• The gas from the Xena field is processed along with gas from the Pluto field at the Burrup LNG Park.
• The initial phase of the Pluto project involved an unmanned, remotely operated offshore platform connected to subsea wells. Gas is piped to shore via a 180 km pipeline.

Recent Developments

• TechnipFMC was awarded a significant integrated Engineering, Procurement, Construction and Installation (EPCI) contract for the development of the Pyxis and Xena fields. This contract includes designing, manufacturing, delivering, and installing subsea equipment such as subsea production systems, flexible flowlines, and umbilicals.

Infrastructure and Capacity

• The Pluto LNG project, including the Xena field, involves a gas processing train that has been expanded to include a second train (Pluto Train Two) which will process gas from the Scarborough field. The first train is being refurbished to process additional gas from the Scarborough field.

Contractors and Suppliers

• Several contractors are involved in the project, including TechnipFMC for subsea hardware, Foster Wheeler WorleyParsons for front-end engineering and design, and CPB Contractors for preparing the LNG train site.

Environmental and Technical Aspects

• The gas from the Pluto field, which includes gas from Xena, is naturally low in carbon dioxide, around 2%, which is lower than much of the other gas in the region.
