The economics change when you’re in oil country. My beautiful little province has oil wells drilled between 250 and 2900 metres. Due to corporate ‘issues’ many of these wells are orphaned and remediation becomes a provincial problem. With deep holes and provincially owned electricity and gas companies, geothermal makes more economic sense; it’s robbing a benefit from a big cost centre.
I went to high school with two guys who are working on geothermal as a means to remediate orphan wells. I’m biased in their favour, but the numbers make a lot of sense.
