The Western Surat Gas 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 completed the first pilot on the Glenora block in December 2016, and commenced appraisal testing in 2017
  • Senex sanctioned a $50 million investment program in February 2017 to further appraise the acreage:
    • Drilling of 30 wells on Glenora and Eos blocks (eastern area of the project)
    • Construction of gas and water handling infrastructure
    • Appraisal activities west of Eos block

Senex is progressing towards full field development and has a near term focus on:

  • Expanded appraisal program in areas adjacent to Glenora and Eos
  • Working towards investment decision on sales gas infrastructure and next phase of drilling
  • Delivery of financing strategy for overall project development
  • Securing regulatory and environmental approvals

Senex is committed to working closely with all stakeholders, including landholders, Native Title holders, community, industry and government.
