Brisbane-based coal seam gas explorer Comet Ridge Limited announced that the first well in its three-well drilling campaign in the Galilee Basin has been successfully drilled and tested in ATP 744P in the Galilee Basin, central Queensland, with the rig released on 22 October 2012.
Comet Ridge holds 100 per cent equity in ATP 744P.
The Gunn 2 well is located 93 km NNW of Aramac and 576 km WNW of Gladstone. The well was spudded on 10 October 2012 and reached a total depth of 1,050 metres. A total net coal thickness of 16.2 metres was intersected in the Permian Betts Creek Beds with five potential reservoir coals contained in this interval.
After wireline logging was conducted, a formation scanner was run to identify natural fractures in the coals. Wireline conveyed testing tools were then used to flow test four separate coal intervals in the Betts Creek Beds, including two coal intervals in the base of the section that had previously not been tested in the Gunn Project Area.
All four coal intervals tested demonstrated good to excellent productivity.
Seven-inch diameter production casing has been run and cemented in place and the well will be completed for production in early November with production tubing and a pump to be installed.
Managing Director, Tor McCaul, said he and the Comet Ridge technical team were extremely pleased with the productivity of the coals in this well. Mr McCaul also said that the well flags an important milestone for the Company, as the first production well for Comet Ridge in the Galilee Basin.
He commented, “Our forward plan, as outlined in the recent capital raising presentation in August, is to complete this well for production and then to conduct an Extended Production Test (EPT). This single well EPT is a significant step, ahead of our planned pilot scheme. The EPT on Gunn 2 will give us good quality water data and enable us to critically assess our completion methodology. These will be key inputs for designing our full pilot production scheme next year with the objective of starting to move our significant Contingent Resources over to Reserves.”
The rig will now move southeast to drill Schmitt 1, followed by Cernan 1, as Phase 1 of the farm-in to the Lake Galilee Farm-in Area (in ATP 1015P), announced in July 2012 (see map on page following). These two wells will be cored to measure key coal properties and whilst wireline conveyed testing tools may be utilised to examine coal productivity, there are no current plans for Extended Production Tests on these two wells.
