Bass Basin — project

Beach's operated offshore gas project in the Bass Basin (BassGas), producing from the Yolla field. A low-cost production optimisation initiative and well interventions drove a 91% increase in FY25 production to 1.4 MMBOE and a 2.7 MMBOE increase in 2P reserves; net-to-Beach 2P reserves are 4.3 MMBOE (gas 17 PJ), all developed, with a large 2C contingent resource of 31.3 MMBOE capturing the Trefoil, White Ibis and Bass discoveries. Future development includes potential drilling and abandonment of suspended wells (Trefoil 1, Yolla 1).
