Percussive Hammer Enables Geothermal Drilling

In 2013, Sandia National Laboratories (SNL) successfully completed the development of a high-temperature drilling technology able to withstand the harsh conditions present in geothermal reservoirs. SNL developed and tested a high-temperature downhole motor that includes an indexing tool for use with commercially available percussive hammers. Conventional pneumatic down-the-hole-hammer drilling systems—widely used in the mining and oil and gas sectors—perform well in hard rock environments and are capable of removing a volume of rock with low energy input.
