Surface casing stabilizer and hanger and method of employing the same
A two part, sectioned tapered cylindrical hanger and stabilizer threaded on its inner periphery which threads are broken circumferentially by longitudinally extending slots defining right angle edges which frictionally grip an enclosed metal well surface casing section. The cylindrical hanger sections are further slotted on their outer periphery longitudinally to facilitate lodging of the hanger in the casing conductor to fixedly locate the upper end of the surface well casing within the conductor in concentric relation therewith. The surface well casing extends the length of the hole, and during the installation procedure, concrete is forced downwardly through the center of the casing and caused to rise between the casing and the wall of the bore hole to lock the lower end of the surface casing to the bore hole. The vertical edges of the semi-circular hanger sections abut and are locked together by locking bars fitting within opposing recesses within the upper ends of the semi-annular hanger sections. T-bar handles threaded to the sections facilitate their transport and mounting to the upper end of the casing conducter.
