Comet Ridge to start coalbed methane production

World Coal,

Comet Ridge will soon begin production of coalbed methane (CBM) in Queensland, Australia.

The company is set to place the Mahalo 6 vertical well into production with operator Santos preparing to install the pump.

Mahalo 6 was intersected by the Mahalo 7 surface to in-seam horizontal well that was designed to maximise the use of current reservoir data and has been positioned inside the current pilot wells.

It will be used as a production well to lift the water and gas from Mahalo 7.

Detailed analysis of production data from both Mahalo 3 and Mahalo 4 showed significant changes in gas and water rates very soon after the Mahalo 7 horizontal well entered the coal seam.

This shows positive signs of connectivity between the horizontal well and its vertical well neighbours.

Mahalo hosts Best Estimate Contingent Resource of 107 petajoules.

Comet Ridge has a 40% interest in ATP 337P, while Santos holds 30% and Australia Pacific LNG has the remaining 30%.
