Abstract (en)
[origin: WO2008144096A1] The present invention provides a method and system for the generation of, the utilization of, the processing of, and the maintenance of a heterogeneous solid-particle impactor- laden fluidic-process circuit that incorporates a particle- injector system and a fluidic-amplifier jet head to produce a conical-shaped cutting jet of fluid and solid-particle impactors that perform functions during the boring, well-bore conditioning, and/or controlling the inclination and azimuth of deep subterranean well bores during their construction.
