Australia-listed Comet Ridge disclosed Tuesday that it has spud the last of its pilot coal seam gas (CSG) wells – Mira 2 – planned under the Mahalo joint venture.
The well, sited at the company’s ATP 337P Mahalo asset in the onshore Bowen Basin, Queensland, will be drilled to a depth of 1,017 feet (310 meters) and undergo coring through the main Castor Pollux reservoir.
The company drew up a longer drilling schedule – around seven days – for Mira 2, due to the well's coring requirements, Comet Ridge's Managing Director Tor McCaul confirmed Tuesday with Rigzone. Unlike Mira 2, the company's previous three pilot wells did not need coring; hence drilling works could be completed within four to five days.
Following Mira 2, four step-out core holes will be drilled to further extend the area available for booking reserves in the Mahalo block.
The Mira 2 well is sited less than 1 mile from the three recently drilled Mira pilot wells, and around 155 miles (250 kilometers) west of Gladstone in central Queensland.
Meanwhile, Comet Ridge is in the midst of constructing field facilities and tanks needed at the Mahalo pilot project. The company is targeting for start-up of the facilities by the end of 1Q 2013.
Comet Ridge holds a 35 percent interest in the permit, while Santos and APLNG each hold a 30 percent share. Stanwell Corporation, which retains an option to increase its share in the project, holds the remaining 5 percent stake.
