Redfloyd,

I couldn't say with certainty, but the rig seems very versatile going by the recent job they did for Woodside which required a shallow hole with a 1.7m diameter. I don't know if these sort of diameter can be translated at depth.

I've attached the initial announcement from the Woodside job which was successfully completed a few weeks ago.


Coretrack Limited (ASX Code: CKK) is pleased to announce that its wholly owned subsidiary, Globe Drill Pty Ltd (?Globe Drill?), has successfully secured a commercial drilling contract with Woodside, requiring it to drill a shallow but unusually large 1.7 metre diameter drill hole in Karratha, Western Australia. The powerful GT3000 drill rig, being the only rig available in Australia powerful enough and manoeuvrable enough to drill this hole, will be mobilised away from the Merredin test hole to provide Woodside with this
valuable service as soon as a low loader has been secured to transport it to Karratha.
Globe Drill General Manager, Mr Warren Strange, said ?There are a number of unique aspects to our GT3000 and the capacity to drill very large diameter holes is one of them. The rig is also fast and easy to mobilise and can drill multiple drill holes without too much additional cost and these aspects ultimately ensured that our rig was the obvious choice for the Woodside contract?.
?Mobilisation costs alone for large oil and gas style rigs can be in the millions, significantly adding to the cost of each hole. The GT3000 can be transported on the back of a low loader with minimum effort and only needs a handful of support trailers, significantly lowering the cost of each hole. Importantly and
uniquely, we can penetrate quickly through hard rock using our air hammer and then switch to conventional mud rotary drilling when ground conditions demand it. Other oil and gas style rigs do not have the option to use an air hammer as they are generally only set up for mud rotary drilling? said Mr Strange.

Whilst I might sound like I'm ramping another company (of course I'd like to see CKK SP up), I've been invested in BPT and Petratherm a lot longer and would love to see this project succeed, so anything that will assist that would be great. I'm also a bit of a greeny, and geothermal appears the best electricity source if the technology is successful.
