Australia's Comet Ridge, a coal stream gas explorer, has started drilling the onshore Mahalo 6 well following its success with Mahalo 3 at the ATP 337P permit, the company's managing director Tor McCaul told Rigzone in a telephone interview Monday.
Mahalo 6 is the second well to be drilled in Comet Ridge's four-well drilling campaign.
Mahalo 6, which was spud on July 22, 2012, will be drilled to a depth of 984 feet [300 meters] and is targeting the Castor-Pollux seam in the Bandana Formation, McCaul said. "As Mahalo 6 is a shallow well, drilling works can be completed in four to five days," McCaul added.
Comet Ridge announced on Monday in a statement that it had completed drilling the Mahalo 3 well. Analysis of flow testing in Mahalo 3 has shown that the Castor-Pollux seam has sufficient permeability to enable the well to be utilized for pilot production. The well was cased on July 21, 2012. The rig, Ensign 62, which was used to drill Mahalo 3 was mobilized to Mahalo 6 on the same day. Mahalo 3 was drilled to a depth of 984 feet (300 meters).
Comet Ridge is aiming to drill Mahalo 4 and Mahalo 5 in the weeks ahead.
Under the company's original plans, Mahalo 4 was scheduled to be drilled after Mahalo 3.
However, "unusually wet conditions" in Queenland's Bowen Basin had forced Comet Ridge to make changes in its drilling schedule, McCaul said.
Comet Ridge's ATP 337P Mahalo asset is located in the Denison Trough area of Queensland's Bowen Basin near Rolleston, and covers an area of 382 square miles (989 square kilometers).
Comet Ridge holds a 35 percent stake in the permit, while Santos and APLNG each hold a 30 percent stake. Stanwell Corporation holds the remaining 5 percent stake.
