Comet Ridge geophysics for CSG identifies major sub-basins
6 May 2010 - Brisbane-based coal seam gas explorer Comet Ridge says its regional aeromagnetic and radiometric surveys in its Buller and Waikato permits have identified major sub-basins as well as obtaining structural information.

Comet Ridge says acquisition and interpretation of the geophysical data is complete for its north Waikato block, PEP 50280, and almost complete for its Buller block, PEP 50279.
Additional depth to magnetic basin modeling has been commissioned for the greater Reefton area to aid in definition of the basin and in planning the second phase of the surveying. This will use gravity survey methods and is expected to be done in late 2010.
Comet Ridge’s wholly-owned New Zealand subsidiary Chartwell NZ is carrying the geophysics work.
Comet Ridge also said that it has received about 40 km of seismic data for the Buller permit in a data trading exercise with a neighbouring resources company. The seismic line data will be integrated with the recent airborne geophysical data and will help select future drilling locations.
Meanwhile the first of two deep coal seam gas pilot wells in the Greymouth Petroleum, Mining Permit 50100, Macdonald 6P began drilling in late March 2010. This well and a second following well Macdonald 4P, are planned to be drilled to approximately 1,200 m to intersect and evaluate the Brunner and deeper Paparoa Formation coal measures.
The intention is to case both wells with a 7 inch production string.
Comet Ridge said that encouraging results were obtained from the nearby Macdonald 5C core hole.
