Krafla magma testbed (KMT): Engineering challenges of drilling into magma and extracting its energy

Preparations are underway for drilling well KMT-1 of the Krafla Magma Testbed at Krafla, Iceland to sample and instrument the margin of a rhyolite magma body. The project is driven by the need to understand magmatic systems, to improve volcano monitoring strategies, and to develop next-generation, h...

Description
Summary:Preparations are underway for drilling well KMT-1 of the Krafla Magma Testbed at Krafla, Iceland to sample and instrument the margin of a rhyolite magma body. The project is driven by the need to understand magmatic systems, to improve volcano monitoring strategies, and to develop next-generation, high-enthalpy geothermal energy. The planned depth of the well is 2100 m with cemented casings to 2040 m and a 8 ½” open hole section for coring to 2010 m. The geology for KMT-1 is well known and the well will be located close to IDDP-1 where magma was unexpectedly intersected at 2102 m depth in 2009.
