SYSTEMS AND METHODS FOR USING ROCK DEBRIS TO INHIBIT THE INITIATION OR PROPAGATION OF FRACTURES WITHIN A PASSAGEWAY THROUGH SUBTERRANEAN STRATA

摘要

Systems and methods usable to urge a passagewaythrough subterranean strata, place protective lining conduit stringsbe-tween the subterranean strata and the wall of said passageway withoutremoving the urging apparatus from said passageway, and targetdeep-er subterranean strata formations than is normally the practice forplacement of said protective lining conduit strings by providingappa-ratuses for reducing the particle size of rock debris to generate lostcir-culation material to inhibit the initiation or propagation ofsubter-ranean strata fractures.
