State Gas is optimistic about the prospects of developing a substantial gas project at Rolleston-West on the back of data from the Rougemont 6 vertical well.

The company today announced the successful drilling, wireline logging and casing of the Rougemont 6 well, 1.5km north-east of the existing Rougemont 2/3 dual lateral well system in the southern Bowen Basin.

State Gas managing director Doug McAlpine said the results suggested strong consistency across the extensive Bandanna coal measures at Rolleston West.

“Establishing a maiden 2P reserve in conjunction with production testing of Rougemont 5 and 6 remains the company’s immediate objective,” he said

The Rougemont 6 well reached a total target depth of 572m and coal intersections commenced around 404m, with 8.1m of net coal logged.

The rig is now being relocated to the Rougemont 5 vertical well site.

Drilling results from Rougemont 5 and 6, including wireline logs and production testing, are expected to support accreditation of a maiden 2P reserve of 30-50 PJ for the project.

Successful outcomes from the program will enable the company to submit a petroleum lease application over a substantial portion of ATP 2062 and advance discussions with potential end users and pipeline infrastructure providers.

Drilling at the two new exploration/appraisal wells is fully funded under a $5.5 million Queensland Government Frontier Gas Exploration Program.
