Old Oil Wells Tipped to be Geothermal Power Source

Abandoned oil wells could generate enough electricity to power a city the size of Christchurch, according to a study from Crown research institute GNS Science.

Temperatures at the bottom of about half of New Zealand’s 360 abandoned on-shore oil and gas wells are above the critical 80C needed to produce geothermal power, says scientist Agnes Reyes.
