Comet Ridge Completes Mahalo CSG Project

Coal seam gas explorer Comet Ridge Limited has completed its four well drilling programme at its Mahalo pilot project in ATP 337P, north of Rolleston in the Bowen Basin in central Queensland. 

The well results have been very positive, and facilities will now be constructed to develop the first production pilot in the Mahalo area.

The Mahalo field is located approximately 260 km west of Gladstone with Mahalo 5 situated 280 metresto the southwest of Mahalo 3. Mahalo 5 is the fourth and final well in the current pilot drilling programme. The Mahalo 5 well reached a total depth (TD) of 312 metres on Monday 30 July, intersecting a total of approximately 7.8 metres of net coal, with 6.8 metres of this coal in the main Castor-Pollux seam.

All four pilot wells have exhibited good continuity and thickness of coal across the main reservoir section, the company said.  The JV intends to plan, design and construct the pilot facilities for expected commissioning late 2012.

Pilot well drilling in the Joint Venture’s second pilot, Mira, will be conducted later in the year, followed by a further four core holes to extend the delineation of gas in the block.

The objective of both these pilot production projects is to demonstrate commercial gas flow s in ATP 337P Mahalo, with the intention of achieving an early initial reserves certification.
