Project Profile
Location: North Perth Basin, Western Australia
Gross 2P Reserves: 460 Bcf of gas
Production: 1.35 MMscf/d
The Senecio discovery is located in the north Perth Basin, Western Australia. Analysis of pressure tests conducted in November 2012 and other data captured since the fracture stimulation has confirmed permeability of between 0.03 to 0.06mD, which is within the pre-frac estimated range. A successful flow test in September 2012 reported a stabilised gas rate of 1.35 MMscf/d from a 5m perforation interval, demonstrates potentially commercial reservoir flow capacity. Senecio is estimated to hold reserves of 4.4 MMboe (equivalent to a gross resource of 50 Bcf of wet gas). Previously interpreted 2D seismic data indicated a potential estimated recoverable volume of at least double the quantity currently booked. The prospect of commercialising Senecio provides strong encouragement for the development of other tight gas opportunities in the Perth Basin, including the Corybas discovery and the High Cliff discovery (the latter in the Arrowsmith-2 well). The Joint Venture partners in Senecio-2 are AWE Limited (via subsidiaries) (Operator) with 50% and Origin Energy Resources Limited with 50%. The Waitsia gas field was discovered in September 2014 and, together with the Senecio gas field. Initial production at the Senecio and Waitsia fields may start as soon as 2016, after what may be the largest onshore natural gas discovery in Western Australia since the 1960s. The project could supply as much as 10% of the Western Australian market in the next 10 to 20 years. It is estimated that Senecio and Waitsia could hold 360 Bcf of gas and potentially more.
AWE Ltd. has commenced commercial gas sales from Stage 1A of the Waitsia gas project in production license L1/L2 in the onshore Perth Basin, Western Australia on time and within the approved budget of US$13.6 million (AUD 18 million). (August, 2016)
The development concept selection process for Waitsia Stage 2 has begun and 2 new appraisal/production wells are planned to be drilled in 2017. (August, 2016)
