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

Project Status

Senex delivered first gas from the Project in 2016, with first appraisal wells online as part of the pilot program. 

Senex is pursuing an indicative gas production rate of up to 10 terajoules per day (~0.6 mmboe per year) by mid-20181. Senex expects to:

  • Complete a $50 million drilling program in calendar year 2017, involving drilling of 30 wells and construction of gas and water handling facilities, across the Glenora and Eos blocks;
  • Further its understanding of the resource to support an accelerated project timeline, with potential to drill, complete and connect another 30 to 50 wells throughout 2018;
  • Undertake appraisal activities west of the Eos block in parallel with the major drilling program;
  • Sell raw gas from the Project to GLNG, subject to agreement of commercial terms; and
  • Continue progressing full field development planning in parallel with regulatory approvals, native title and land access activities.

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)
