Comet’s Oz Mahalo Mira 6/2 Well Continues to Impress
Comet Ridge’s Mahalo Mira 6/2 well in Central Queensland, Australia, is exceeding the company’s own expectations and has breached a flow rate of 1.4mn ft3 per day, the company said June 26.
“To get a flowrate of over 1.4mn ft3 per day from a very shallow, single seam well like this, is a tremendous result, but to get it from a well that is only about 900 metres in coal is particularly pleasing, given that development well lengths on a number of other fields are in the 1500 to 1800 metre range,” Comet’s managing director Tor McCaul said.

The company added that the performance could be improved by increasing the length of the well and targeting multiple zones. And, that the strong flow rates should result in a reduction in the number of wells and the amount of associated surface infrastructure required for the project, which would reduce capital cost requirements.
McCaul also said that the joint venture is currently putting the final touches on a plan to drill several wells commencing in September, which includes the Mahalo block’s first long dual horizontal well which could effectively be the development well style that is replicated many times across the block in the future.
Equity participants in the Mahalo coal seam project along with Comet Ridge (40%) are Australia Pacific LNG (30%) and Santos (30%).
The project is located about 240 kilometres west of Gladstone, which is home to the Australia Pacific LNG terminal and Santos’ Gladstone LNG facility, along with Shell’s Queensland Curtis LNG export project.
The Mira 6 horizontal well was drilled in November last year.
