Registration is currently open for a webinar on new downhole hammer drilling technologies on November 23 hosted by TWI and part of the Geo-Drill project.
As part of the dissemination of the EU-funded Geo-Drill project, TWI will host a webinar on “Development of DTH Hydraulic Percussion Drilling Systems” with Volker Wittig from Fraunhofer IEG as a speaker.The webinar will be held on November 23, 2022, from 13:00 to 14:00 GMT.Registration is free and can be done through this link.

Down-the-hole (DTH) hammer drilling technologies have been used successfully for many years in the mining industry, as well as in the oil and gas industry.There are both air and fluid/liquid powered systems on the market.
DTH hammers typically use a piston moved by hydraulic power or compressed air, applying alternating loads on the bit to crush the rock at the bottom of the hole, thereby drilling a hole.Today, most DTH hammer systems run on air or other clean fluids, so quality largely determines tool life.As a result, fluid consumption, well control, and cuttings transport are more difficult compared to conventional rotary drilling technologies using any drilling mud.

Rock Button Bit Therefore, new DTH hammer systems that can work with drilling mud for deep drilling in hard rock have been being developed.For example, a novel DTH-type percussion mechanism that works with a single moving part developed by Fraunhofer IEG will be presented.Such type of hammers will help make percussion drilling much more successful and cheaper.
