so that tensioner 404 comes into contact with end cap 406 and the pulling force is transferred to the cables though tensioner 404 retainer support 402 b and retainer 402 a the cable pull force is applied through hose fitting 302 so that pulling on the tensioner assembly pushes thrust liner 300 upwards this configuration makes it possible to pull flexible jet lance 116 and the attached jet drill out of the lateral borehole and out through the deflection shoe in one exemplary embodiment there are eight cables 400 for providing a tensile pull capacity of 4000 lbf this load capacity enables the operator to observe variations in pull load which can be an indication of hole instability a hose spacer 414 is threadably engaged with liner 408 to accommodate variability in the length of hose protruding from thrust liner 300 a crimped hose fitting 410 connects the hose to an inlet adaptor 306 of the tensioner assembly with a nut 412 to summarize flexible jet lance assembly 116 and tensioner assembly 114 provide a number of functions required for drilling a zero radius lateral bore including 1 transmitting high pressure fluid to the jet drill 2 transmitting thrust to push the flexible jet lance assembly though the deflection shoe and to react the thrust of jet drilling and contact forces without shearing or buckling 3 transmitting tension to pull the flexible jet lance out from the borehole and 4 providing sufficient transverse flexibility to pass though the deflection shoe passage as shown with minimal thrust referring to fig8 a 8 b and 8 c deflection shoe 120 is held fixed in the borehole.
