the surface any borehole hole collapse will be limited by the perforated liner and fluids which enter the liner 6 and flow to the surface or to a pump placed downhole the jetting fluid delivery tubing 2 inside liner 6 provides only minor obstruction to fluid flow in either direction since there will remain ample open fluid flow area 7 inside the liner 6 alternatively in a more preferred embodiment the jetting liquid delivery tubing 2 is detached from nozzle 1 as described above or alternatively by a break away device or procedure such as strong pulling on the delivery tubing 2 this will leave the liner 6 completely clear and the shoes 42 can also be removed therefore the invention can be employed for fluid production from a reservoir 20 or for fluid injection as may occur in water disposal and it may be employed in both consolidated rock or un consolidated rock the material of construction for the liner 6 must have sufficient strength to hold back sand from borehole collapse and sufficient flexibility to make the sharp turn from vertical to horizontal at the shoe 42 a number of materials are candidates such as steel mentioned above but also perforated kevlar tubing particularly where fluid such as water is being supplied to borehole 10 and not being withdrawn in order to maintain maximum strength a favored embodiment for perforation is small holes of a size appropriate to exclude sand or other grains but to permit fluid passage the methodologies for determining the maximum perforation size are well known to those skilled in the art fig3.
