Twelve of the original 24 production wells at the field recorded their best weekly average flows last week, the company said. Berwyndale South-60 last week flowed an average of 3.54 million cubic feet per day (MMcfd), while the field's oldest well Berwyndale South-9, drilled in May 2004, achieved 2.97MMcfd from only the lower Juandah seams.
QGC said it was now selling an equivalent of 9.65 petajoules per year, about 75% higher than its original 5.4PJ target.
As a result, managing director Richard Cottee said, "QGC has today established itself as the largest independent seller of coal seam gas in the Queensland market."
QGC is operator and majority owner (90%) of Berwyndale South, together with partner Sentient Gas Australia (10%). The field is QGC's first commercial CSM operation and is located close to Chinchilla in southern Queensland.
