Whitebark Energy is advancing development plans for the 100%-owned Warro gas field onshore Western Australia, following a renewed technical evaluation.

Technical Re-evaluation and Development Strategy

Recent petrophysical analysis of all six Warro wells identified thicker, mobile gas-bearing intervals, particularly in the high-quality Yarragadee Lower formation. The analysis concluded that previous completion and stimulation programs were too broad, inadvertently including water-bearing zones. This revised evaluation has better delineated dry gas zones with minimal mobile water, materially improving the assessment of the field's commercial potential. The company plans to integrate production test data from Warro 3 and 4 to design a targeted retest focused on dry, gas-saturated intervals to establish a sustained commercial gas flow.

Commercial Plans and Context

The operator intends a fast-track development by attracting a farminee within the next year. Following a successful farm-in and the establishment of commercial gas flow, testing and production planning would commence. The company raised A$750,000 via an institutional share placement for Warro's development. RISC Advisory has been engaged to perform a commerciality assessment as part of four critical technical and commercial studies launched in November. The Retention Lease (RL7) containing the field is due for renewal in March-April 2026, requiring a robust testing and abandonment plan by the first quarter of next year.

Field Background and Resource

The Warro gas field is located 30km from the Dampier-to-Bunbury pipeline and 200km north of Perth. Previous operators confirmed a large gas resource through 3D seismic and four vertical wells, with test flows of 1-2 million cubic feet per day despite limited stimulation and high water cut. The total legacy resource estimate ranges from 4.4 to 11.6 trillion cubic feet of gas in place. The asset was retained following a 2021 internal restructuring, against a backdrop of improved commodity prices and renewed activity in the Perth Basin.

Other Portfolio Activity

Separately, Whitebark aims to attract a farminee for its 100%-owned Alinya project in the Officer basin within the next three to six months, before planning the drilling of the Rickerscote-1 exploration well.
