Mission Accomplished!

Mission Accomplished!!! Mountain Home well complete!! This past Tuesday we completed drilling of the Mountain Home core hole at Total Depth of 1821.5 meters (5976 feet). Yesterday we set temporary casing string to TD for long-term temperature monitoring. We will return to complete logging of the hole, and to do the plug-and-abandon, sometime this coming summer. Geothermally, this hole was a great success, with a major fracture system flowing hot water to the surface -- an artesian well. Last bottom hole temperature (projected to equilibrium) was 160ÂșC. We are now faced with completing the lithologic description of over 3 miles of core from our three* drill holes. We are about half done with this effort, and it will take many months to complete the rest. [*actually four, since we did two separate holes at Mountain Home]. Project overall, we drilled 6291 meters total depth, and collected 5430 meters of core, including basalt, rhyolite and sediment. This is enough to keep a lot of people busy for a very long time. Congrats to everyone involved.
