Waitsia reserves boost for AWE

The major upgrade of 2P Reserves and updated 2C Contingent Resource estimates follows an extensive evaluation of new core data acquired in 2015 from the Waitsia-1 and Waitsia-2 wells and further analysis of well test data from the Senecio-3 and Waitsia-1 wells.

AWE Managing Director David Biggs said analysis and evaluation of the full well dataset allowed AWE to significantly increase the company’s previous estimate of gross recoverable gas and increase the 2P reserves.

“This significant reserves upgrade is another very successful step in the ongoing appraisal of the Waitsia gas field and underlines the strategic importance of this exciting onshore gas project,”? said Mr Biggs.

“Using data gathered from the three appraisal wells drilled to date, we have made substantial progress on field modelling and we are currently finalising concept selection options for the full field development of Waitsia and surrounding fields.”?

Construction and technical work for Stage 1A of the Waitsia gas project is proceeding on time and budget and AWE anticipates delivering contracted initial volumes of 10 TJ/d of gas into the Western Australian domestic market from the third quarter of 2016.

Stage 1A of the project would see gas wells connected to the refurbished Xyris Production Facility, with treated gas from the facility to be delivered to the 416 km, 350 mm Parmelia pipeline for domestic consumption.
The Waitsia Pipeline and flow lines will be constructed in three stages:

  • Stage 1 – Senecio-03 to Northern Hub Site Flow line
  • Stage 2- Waitsia-01 to Northern Hub Site Flow line
  • Stage 3 – Northern Hub Site to the Xyris Production Facility.

The pipeline and flow lines will be carbon steel, externally coated line pipe, constructed and installed in accordance with AS2885 between 900 mm and 1200 mm below natural ground level and deeper as required to traverse the Parmelia pipeline.
