This study was a part of the research project INNO-Drill(Technology platform for research-based innovations in deep geothermal drilling)funded by The Research Council of Norway(grant 254984);industry partners.
This paper examines the performance of three families of percussive drilling methods,Churn(CD),Down-the-Hole(DTH),and Top-Hammer(TH),through the prism of time scales.These time scales characterize different aspects of...
