OK. I'm not somebody in the know, I've read a bit, and I'm curious. Canada has not developed any of it's geothermal energy potential (I'm talking commercial generation, not home heating). I understand there is regulatory, investment etc. issues. My question is a little more simple for those on the drilling side of the oil industry.
What sort of temperatures do our rigs see at the bottom of their drilling cycles? Is it even recorded?
Temperatures depend on depths of the target zone which varies a lot in the oil & gas industry. I am not on the drilling side so I'm not 100% if during open hole logging the temperature is recorded. I do know that the programs I see all the time on the completions side give a estimated bottom hole temperature.
The temperature I see on programs are typically between 85C and 115C. We are talking 2800m to 3500m in depth typically.

So you might see boiling temps. Good for heating I would guess.
Pretty much all directional/horizontal drilling tools monitor and transmit real time temp data from downhole as the well is drilled. 90-100C is the upper end in western Canada for the most part.
My area has a very thin crust and huge potential for geothermal power production. The town has been trying to get the ball rolling for years now but the govt. are really dragging their feet. The Chinese have shown interest in the last year so am hoping that somebody actually pulls the trigger on this as this is clean energy and the outflow from the power plant can be used to fuel a hotsprings tourist attraction.
