International Classification:

E21B 416
E21B 708
E21B 1720

US Classification:

175 62

Abstract:

An apparatus and method are disclosed for applying thrust (weight on bit) to a drill bit when drilling with a flexible drilling shaft while creating perforations in a cased well. The thrust is applied directly to the drill bit instead of applying it to the drill bit through the flexible drilling shaft. A support bracket is also in contact with a piston and is in slidable contact with the tool housing. A portion of the piston is positioned inside a chamber in the housing and is slidably attached to the chamber walls. As hydraulic fluid flows into the chamber opposite the piston, the piston is forced toward the drill bit. As the piston moves toward the drill bit, force is exerted on the support bracket which causes the bracket to move toward the drill bit. This force is transferred to the drill bit during the drilling process, thereby supplying the force (weight on bit) needed by the drill bit to effectively drill through a desired material.

International Classification:

E21B 3312
E21B 4701

US Classification:

166382

Abstract:

A method and apparatus for anchoring a tool within a cased borehole wherein at least one piston connected with respect to the tool includes an associated anchor shoe. The anchor shoe has a penetration means, such as a plurality of wheels having a sharp outer periphery, for engagement with the cased borehole. A packer having a rigid component, such as a plurality of concentric rings, is connected with respect to the tool, opposite the piston. The packer may also have a sealing member for creating a sealed engagement between the tool and the cased borehole. When the piston is extended, the anchor shoe contacts the cased borehole and centers the tool with respect to the cased borehole. When the piston is extended, the packer also engages the cased borehole and maintains the position of the tool as well as creating a sealed connection between the tool and the cased borehole.

International Classification:

E21B 2906
E21B 43112

US Classification:

175 52

Abstract:

An apparatus and method are disclosed for the removal and replacement of the used drill bit after each perforation through casing, cement, and into rock while using a flexible drive shaft. This apparatus involves both a bayonet-style "quick connector" between the flexible shaft and the drill bit and a cartridge that holds the drill bits while they await their turn to be used. The apparatus also has a means for indexing the cartridge so that the flexible shaft can have access to each of the drill bits in the cartridge. The method disclosed involves the process of connecting the flexible shaft to the drill bit at the start of the perforating process, the disconnecting of the used bit at the end of the perforation, and the indexing of the cartridge so that the next drill bit is in line with the flexible shaft for the next perforation.
