Geothermal energy has been harnessed for recreational uses for millennia, but only for
electricity generation for a little over a century. Although geothermal is unique amongst …

Managed pressure drilling (MPD) is a form of drilling that allows greater and more precise
wellbore pressure control than conventional drilling. In addition, the mud weight used will be …

Plasma stimulation is a form of waterless fracturing as it requires that only the wellbore be
filled with an aqueous fluid. The technique creates multiple fractures propagating in different …

Employing novel drilling, and tunneling methods are active area of study since 1930s. In the
present report, an Experimental study of the thermal impact of laser and plasma torch on …

Introduction. As compared with other ways of thermal destruction of rocks, the rock
destruction by low temperature plasma jet has advantage in terms of distribution of cracks in …

Purpose-experimental research on the high-speed interaction of the heat transfer medium
jet with the surface of the borehole in the process of fragile rock destruction with the purpose …

Purpose. To study rock spallation dynamics in the process of the borehole thermal reaming
and analyze energy consumption of the borehole thermal reaming process by plasma jets of …

This study discusses fracturing in geothermal reservoirs using hydraulic fracturing and
plasma pulse fracturing. The hydraulic fracturing technique develops two-wing fractures that …

Efforts have been made to increase efficiency and reduce costs in all industries, especially
in the oil and gas industries. Today, the use of modern technologies to reduce costs and …

This paper discusses principles behind thermal drilling technologies including LJD.
Preliminary lab and field tests of LaserJet thermal drilling are being analysed, showing …
