Tight oil or gas formation fracturing process

Claim 1

The process of fracturing tight oil or gas formations by drilling into the the tight oil or gas formation from a selected depth in a well borehole in the tight oil or gas formation a band consisting of one or more layers which consist of small holes drilled perpendicular from the well borehole into the tight oil or gas formation, the small holes which comprise a layer are drilled at the same depth and from as many points that can be drilled around the circumference of the well borehole so the small holes will radiate out from the well borehole into the tight oil or gas formation, injecting liquid explosive into the small holes after they have been drilled and igniting said explosive to exert fracturing pressure on the tight oil or gas forMation from the small holes, wherein the method used in drilling the small holes consists of lowering a tubing string into the well borehole with a ninety degree elbow attached to the downhole end of the tubing string string and setting the tubing string so the open end of the 90* elbow interfaces with the well borehole wall where a small hole is to be drilled, lowering a drill pipe string down through the tubing string with a flexible hollow shaft attached to the downhole end of the drill pipe string, a tool joint attaching the uphole end of the flexible hollow shaft to the downhole end of the drill pipe string and a drill bit attached to the downhole end of the flexible hollow shaft by means of a tool joint, applying rotation and down pressure to the drill pipe string from the top of the well borehole whereby the drill pipe string rotates and forces the drill bit and flexible hollow shaft through the 90* elbow and drills the drill bit and flexible hollow shaft into the tight oil or gas formation drilling a small hole until the tool joint that attaches the flexible hollow shaft to the drill pipe string is near the point where the tubing string attaches to the 90* elbow, then applying hoisting action to the drill pipe string by the conventional well drilling equipment at the top of the well borehole until the flexible hollow shaft and drill bit have been pulled from the drilled small hole in the tight oil or gas formation into the 90* elbow rotating the tubing string after the drill bit has been pulled into the 90* elbow until the open end of the 90* elbow interfaces with the well borehole wall where the next small hole of a layer is to be drilled, lowering the tubing string when all the small holes of a layer are drilled to the point in the well borehole where the next layer of small holes is to be drilled if the band of small holes requires more than one layer of small holes.
