North Perth L1L2

AWE discovered the Waitsia field, a conventional gas play in the Kingia and High Cliff Sandstone formations, in September 2014 while drilling the Senecio-3 well. With an estimated 178 Bcf gross 2P Reserves and 306 Bcf gross 2C Resources, the Waitsia field is considered to be the largest onshore conventional gas discovery in Australia for the last 30 years.

Exploration and appraisal of the nearby Irwin, Synaphea and Senecio fields, predominantly tight gas plays in the Dongara and Wagina sandstone formations, saw AWE increase gross 2C Resources for these fields to 237 Bcf, bringing the total combined gross 2P Reserves and 2C Resources for Waitsia, Senecio, Synaphea and Irwin to 721 Bcf.

Waitsia is located in the Mid-West region of Western Australia, which has supplied gas to the Perth market for the last 45 years and is well serviced by pipeline infrastructure and facilities. Being an onshore development close to existing infrastructure will ensure that AWE becomes the low-cost producer in a healthy west coast gas market.

When fully developed, the onshore Perth Basin could meet approximately 10% of WA’s domestic gas demand and AWE is actively marketing gas to potential clients in the energy, industrial, mining and transport sectors.

Together with joint venture partner Origin Energy, AWE is planning to commence early stage production of up to 10 TJ/day from two wells (Senecio-3 and Waitsia-1) by mid-2016. Full field development, comprising approximately 20 wells over an area of 50 square kilometres and delivering up to 100 TJ/day, could produce gas for more than two decades. The decision to proceed to a full field development will be dependent on securing gas sales agreements as well as the necessary government approvals.

AWE is committed to the Mid-West community and operates in an open and transparent manner with high levels of community consultation and stakeholder interaction.
