Project Profile
Value: US$150 Million
Location: Exploration Permits EP407 and EP321, Western Australia
Reserves: 11.6 trillion cubic feet (Tcf)
Production: daily production of 90 million cubic feet
Startup Year: 2013
The Warro Gas Field was discovered in 1976 and while it was known to contain significant quantities of high quality natural gas, it is only with advances in gas recovery technology and increased demand for natural gas, that the project has become economically viable. The field covers an area of approximately 7000 hectares and is about 4000m below the surface. The gas is high quality and suitable for sales with only minor dehydration treatment. Infrastructure for the project, should it meet all necessary approvals, will involve production wells, a pipeline to carry the gas to the existing domestic gas pipeline infrastructure, a small gas treatment plant and compressors. is targeting daily production of 90 million cubic feet, or about 100 terajoules, based on its belief it will be able to recover at least one trillion cubic feet of gas from Warro. The gas will be piped to a gas processing plant and then delivered to the ‘Dampier to Bunbury’ and \'Parmelia’ pipelines 30 kilometres to the west.
In 2015, an independent assessment has increased the size of the Warro onshore gas field in WA by over two times. The RISC assessment has increased the GIIP estimate to 11.6 trillion cubic feet (Tcf) on a 100% basis. The new resource estimates follow the two latest highly successful wells which were drilled at Warro-4 as part of the program funded by Alcoa of Australia whereby Alcoa may earn up to 65% of the project. Although accurate estimates for well deliverability will not be available until testing of Warro-5 and 6 is completed, previous estimates done as part of the Shanley Review indicated that wells drilled on a 20-hectare spacing could be expected to yield between 4 - 10 Bcf per well. The impressive results of the review by consultants RISC Advisory6, highlight the immense potential for Warro – already the biggest undeveloped onshore gas field in Australia – to become a major player in the State’s domestic gas market.
