Abstract (en)

[origin: CN103180544A] Systems and methods usable to urge a passageway through subterranean strata, place protective lining conduit strings between the subterranean strata and the wall of said passageway without removing the urging apparatus from said passageway, and target deeper subterranean strata formations than is normally the practice for placement of said protective lining conduit strings by providing apparatuses for reducing the particle size of rock debris to generate lost circulation material to inhibit the initiation or propagation of subterranean strata fractures.
