The Western Surat Gas Project involves the delivery of natural gas from an area spanning approximately 915 square kilometres of Senex permits, north of Roma in Queensland. 

The project is largely located within the Maranoa Regional Council area and adjacent to producing gas fields operated by Santos and Origin Energy.

In September 2018, Senex confirmed the decision to ring-fenced four blocks within WSGP (Eos, Glenora, Tethys and Mimas) and renamed the area Roma North. This was a key step toward making a Final Investment Decision.

Project Status

  • Senex confirmed a Final Investment Decision in October 2018 for Roma North.
  • Senex undertook its first material investment in the project during FY18, delivering 30 appraisal wells with associated infrastructure on the Glenora and Eos blocks.
  • During FY18, Senex received all primary regulatory and environmental approvals necessary to commence development of the project, initially focusing on the Glenora and Eos blocks.
  • In February 2018, Senex sanctioned long-lead items for sales gas infrastructure. The compression facility will have an initial capacity of 16 terajoules per day and be easily expandable given its modular design.
  • As at mid-2018, the conversion of the significant undeveloped 2P reserves on the Western Surat Gas Project (as well as Project Atlas) to developed reserves and production is the overwhelming priority for Senex.
  • Our staged approach to development is initially focused on the Glenora and Eos blocks, against which Senex has booked 190 petajoules of 2P reserves.
  • Senex is committed to working closely with all stakeholders, including landholders, Native Title holders, community, industry and government

Key Project Facts

  • Ownership: Senex Energy 100% and operator
  • Location: 30km north of Roma, Queensland
  • Project Area: approximately 915 sq km
  • Market: 20 year gas sales agreement with GLNG
  • Project Scope: up to 425 wells and associated infrastructure
  • Glenora and Eos 2P reserve position: 32 mmboe (190PJ)
  • Senex will look to hire and buy locally whenever possible

Agreements with GLNG

In September 2015, Senex announced that it had entered into agreements with GLNG for the development of the Project, and in December 2015 Senex completed the sale transaction with GLNG. The agreements include:

  • The sale of a small portion of Senex acreage to GLNG (known as the Maisey block)
  • A 20-year binding gas sales agreement to supply up to 50 TJ/day to GLNG
  • Potential sharing of infrastructure facilities
  • Data sharing including ongoing access to subsurface and production data from the adjacent Roma field (Santos operated)
