Brisbane Firm Restarts Old Queensland Wells
Brisbane-based State Gas has completed gas flow-testing from long-shut-in conventional wells in Queensland, Australia which showed “significant” pipeline-quality gas, the company said January 9.
“The three wells flow-tested and sampled were Primero 1, Aldinga North 1 and Reid’s Dome-4. Drilled between 11 and 37 years ago, these existing wells are located within the northern half of PL 231,” it said.
The company reported that despite the wells being shut-in for such an extended period of time, they flowed “significant gas, at lowest recorded stabilised rates of between 357,000 ft3/d and 658,000 ft3/d." Gas composition results indicate the produced gas represents a similar composition in its natural form to that of pipeline-quality gas, with an average methane content of approximately 96%, average carbon dioxide content of about 1.5% and very low levels of inerts, it said.
