A Grampian-based oilfield service company specialising in drilling innovation, has successfully deployed its equipment in the world’s deepest and hottest geothermal borehole.

The Iceland Deep Drilling Project (IDDP) on the Reykjanes Peninsula is set to become an integral part of Iceland’s geothermal energy production – providing clean, renewable energy by using supercritical steam heated by the earth’s magma.

Drilling took 176 days and involved the deepening of an existing geothermal borehole to a depth of 5km.

The team from Churchill Drilling Tools encountered temperatures of 427°C at a depth of 4,659m – simultaneously creating the deepest and hottest ever geothermal borehole and encountering supercritical conditions at a shallower depth than anticipated.

Mike Churchill, Chief Executive and commercial director said: “Churchill was delighted to secure two world firsts’ on this well. The IDDP well is both the deepest and hottest geothermal well on record and it is a reflection on the DAV MX™ that it was selected to be run in this string.

“The tool has a significant case history in HPHT wells and can withstand a good deal of punishment – both of which suited the client in this unconventional case.

“Geothermal wells are a new area for Churchill and it is a market we are looking to expand as our competition in the segment simply cannot match the resilience of the CircSub.”
