News: Comet Ridge to resume de-watering operations at Queensland gas project

Comet Ridge (ASX:COI) expects the Mahalo 7 surface to in-seam gas well project in Queensland’s Bowen Basin to resume de-watering operations after the joint venture approved a workover to replace the pump in July.

The Mahalo 7 surface to in-seam horizontal well was positioned inside the existing vertical pilot wells.

It was drilled past the Mahalo 3 vertical well, on a path to intersect the down dip Mahalo 6 vertical production well.

While pumping of water from Mahalo 6 was undertaken very conservatively in order to protect the coal reservoir and bring the well on line in a gradual manner, pumping efficiency declined in April with evidence of produced gas running through the downhole pump.

The Mahalo block sits approximately 240 kilometres west of Gladstone in central Queensland and the Joint Venture led by Santos (ASX:STO) has been operating two production pilot schemes at the Mahalo Field Pilot and Mira Field Pilot, since the first half of 2013.

Equity participants in ATP 337P Mahalo are Comet Ridge 40%), Australia Pacific LNG Pty Ltd (30%) and Santos (30%).
