Drilling in supercritical geothermal condition


The aim of the “Drilling in dEep, Super-CRitical AMBients of continentaL Europe: DESCRAMBLE"" project is to develop novel drilling technologies for a proof-of-concept test of reaching deep geothermal resources and to contribute to a low-carbon European society. To achieve this target the first drilling in the world in an intra-continental site at a middle-crustal level will be performed. The test site is an existing dry well in Larderello, Italy, already drilled to a depth of 2.2 km and temperature of 350 °C, which will be further drilled to 3-3.5 km to reach super-critical conditions unexpectedly experienced, and not controlled, in a nearby well in 1979.

The project will be organized into two main phases: (1) Drilling in super-critical conditions, including drilling components, well materials, design and control; (2) Geo-Scientific activities for predicting and controlling critical conditions, which considers petrological, physical and chemical characterization, simulation and monitoring, including high temperature and pressure tools.
