Comet Ridge Gets Positive Results From Queensland CSG Well

Coal seam gas explorer Comet Ridge Limited has said that the Mahalo 3 well, at its ATP 337P Mahalo asset in Queensland’s Bowen Basin, has returned very positive well results in terms of both thicknesses of coal intersected and permeability, across the main coal reservoir section.

The well lies approximately 260km west of Gladstone in central Queensland and was drilled to target the shallow Bandanna Formation.

The  Mahalo 3  well reached a total depth (TD) of 300 metres on Friday 19 July, intersecting a total of approximately  eight  (8)  metres of net coal, with seven  (7)  metres of  this  coal in the main  CastorPollux seam.  The Castor-Pollux is the target of the reserves booking plan currently being executed by the joint venture. 

Analysis of flow testing in Mahalo 3, conducted over this main seam, has shown the Castor-Polluxto have sufficient permeability to enable the well to be utilised for pilot production.  Accordingly, production casing has been run and cemented in place with the rig being released on Saturday 21 July.

Mahalo 4 was due to be the next well  in the four pilot  well drilling sequence, however due to unseasonal  rainfall in  the area, the  well  drilling sequence has been modified to drill the driest sites first.

Subsequently the rig was moved to Mahalo 6, and this well was spudded on Sunday 22 July.  Mahalo 6 has a planned TD of 300 metres and is also targeting the Castor-Pollux seam in the Bandana Formation.
