MyTvsBroke,

This is the email I recieved from a friend of mine who works in Alberta in the oil patch on a drill rig. He is extremely knowledgable in the technical aspects of drilling and different types of subsurface formations we would encounter drilling.

Hi Jim
The hunt was good. We saw lots of big game (elk, moose and deer) but they aren't in season yet, We saw several bear but were either too small or too far away for a good shot. No tyrophys this year but had a blast with the boy (9) and we put a TON of miles on the quads. Got a sunburn and hangover. 2 out of 3 ain't bad, eh?
As far as SRSR goes...I only glanced at the web-site but couldn't really glean too much from it. Typically, the pay-zones aren't that deep so heating isn't generally a problem. When you get into deeper drilling then temps start to rise. Even then, it's not an issue...unless you're in a volcanic area. The drilling done by SRSR is in the "Canadian Shield" and is basically solid rock from the top - down. Standard drilling procedures will be the norm. using a tri-cone rock-bit down to the top of the pay-zone using drilling mud or water to bring the cuttings back up to the surface. Once at the top of the pay-zone, the drill string will be pulled out and the rock-bit will be replaced with a core-barrel. This tool has a circular hollow diamond bit that will cut around a core sample as the sample move up inside the barrel as the bit moves down. Once the core-barrel has cut down to the predetermined depth, drilling stops, the core sample is sheared-off inside the core-barrel and retrieved at surface.

Hope this helps.
