In recent years, to further increase the rate of penetration (ROP), cyclic electrohydraulic
shockwaves drilling (EHSD) has been proposed. It is of great significance to study the rock …

Electrohydraulic shockwave drilling (EHSD) technology can effectively break rocks in the
laboratory. However, there are few studies on the effect of this technology on bottom-hole …

The geothermal energy is one of the most promising sources of electricity on the planet; it is
available almost anywhere on the continents and resources are inexhaustible. The …

The rate of penetration is very low during the development of unconventional gas resources
such as tight gas and marine shale gas, owing to high rock hardness and strength as well as …

Plasma shock wave (PSW) has been proven to be able to destroy rocks and improve the
ROP for conventional rotary drilling. The aim of this paper is quantify the damage caused by …
