Abstract Small-scale laboratory tests of an ultrahigh-pressure jet-assisted drilling system have been carried out in a pressure drilling test stand. Increases in the penetration rate are greatest in permeable rock and are proportional to the hydraulic pressure. The results of field tests with the drilling system are consistent with those obtained in the laboratory.
