Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
188 words
A METHOD OF COATING AN EXPOSED WALL PROTION OF A DRILLED HOLE INTERSECTING A PERMEABLE EARTHEN FORMATION, SAID METHOD COMPRISING: CIRCULATING GASEOUS FLUID ADJACENT AN EXPOSED WALL PORTION OF A DRILLED HOLE WHICH INTERSECTS A PERMEABLE FORMATION SUCH THAT AT LEAST A PORTION OF SAID GASEOUS FLUID ENTERS SAID FORMATION THROUGH SAID EXPOSED WALL PORTION; DIRECTING A CONFINED FLOW OF SEALANT MATERIAL, ISOLATED FROM THE PERIPHERY OF SAID DRILLED HOLE, GENERALLY AXIALLY INTO SAID HOLE; CONSTRICTING SAID AXIAL FLOW OF SEALANT MATERIAL SO THAT ITS FLOW VELOCITY IS INCREASED IN PASING SAID CONSTRICTED FLOW THROUGH OUTLET MEANS; IMPINGING SAID CONSTRICTED FLOW OF SEALANT MATERIAL AGAINST ABUTMENT SURFACE MEANS, SAID ABUTMENT SURFACE MEANS BEING SPACED FROM SAID OUTLET MEANS AND EXTENDING GENERALLY TRANSVERSELY OF THE LONGITUDINAL AXIS OF SAID DRILLED HOLE; SAID CONSTRICTED FLOW OF SEALANT MATERIAL BEING IMPINGED AGAINST SAID ABUTMENT SURFACE MEANS SO AS TO FORM DIVIDED PARTICLES OF SEALANT MATERIAL WHICH ARE DEFLECTED GENERALLY TRANSVERSELY OF THE LONGITUDINAL AXIS OF SAID DRILLED HOLE AND PROJECTED GENERALLY TRASVERSELY OF THIS AXIS AS AN AT LEAST PARTIALLY MIST-LIKE SPRAY AGAINST THE EXPOSED WALL PROTION OF SAID PERMEABLE FORMATION.
