AWE Limited has announced that it has started drilling the Waitsia-3 appraisal well in the northern Perth Basin, Western Australia, as it eyes a final investment decision for full development.
The Waitsia-3 well will be drilled to a planned maximum total depth of 3,706 m MDRT and is forecast to take approximately seven weeks in total to complete. The well is designed to appraise the gas potential in the southern extension of the Waitsia Field, with primary targets being conventional reservoirs in the Kingia and High Cliff Sandstones.
Waitsia-3 is the first of a two well appraisal drilling program planned for the Waitsia field in 2017.
David Biggs, CEO and managing director of AWE, said: “Waitsia-3 and Waitsia-4 will be the last appraisal wells drilled prior to a Final Investment Decision (FID) for the Waitsia Stage 2 full field development. Both wells are expected to be completed as production wells if results are positive."
He added: “Stage 1A of the Waitsia Gas Project continues to exceed our pre-drill expectations. Excellent performance from multiple zones in the Senecio-3 and Waitsia-1 wells has confirmed a high quality conventional reservoir system in the Kingia and High Cliff Sandstones with excellent connectivity.”
In a statement, AWE said that the Pre-Front End Engineering and Design (FEED) work for Stage 2 full field development is nearing completion and the joint venture will be in a position to commence FEED from June.
