  • Patent number: 8678108
    Abstract: A casing drilling assembly includes a profile sub having an interior profile shoulder and secured a casing string. A bottom hole assembly is run into and retrievable from the casing string. Stop dogs carried by the bottom hole assembly lands on the profile shoulder and stop downward movement of the bottom hole assembly, positioning an underreamer below the casing string. A mandrel is coupled to the bottom hole assembly. An elastomeric sleeve encircles the mandrel below a setting ring. A running tool releasably couples to the mandrel and moves the setting ring downward relative to the mandrel to a lower position to deform the sleeve into frictional engagement with the casing string and the mandrel to transmit torque and axial load between the bottom hole assembly and the casing string.

  • Patent number: 7234542
    Abstract: The steel drill string attached to a drilling bit during typical rotary drilling operations used to drill oil and gas wells is used for a second purpose as the casing that is cemented in place during typical oil and gas well completions. Methods of operation are described that provide for the efficient installation of a cemented steel cased well wherein the drill string and the drill bit are cemented into place during one single drilling pass down into the earth. A stabilizer is attached to the drill string that is used to centralize the drill string in the well during cementing operations. A one-way cement valve is installed near the drill bit of the drill string that allows the cement to set up efficiently under ambient hydrostatic conditions while the drill string and drill bit are cemented into place during one single drilling pass into the earth.

  • Patent number: 7036610
    Abstract: A method of drilling and completing a wellbore in a geological formation to produce hydrocarbons from a well comprising at least the following four steps: drilling the well with a retrievable drill bit attached to a casing; removing the retrievable drill bit from the casing; pumping down a one-way valve into the casing with a well fluid; and using the one-way valve to cement the casing into the wellbore. Other methods are described to drill and complete wellbores in a geological formation with different types of pipes following the removal of retrievable, or retractable, drill bits from the pipes by using pump-down one-way valves.

  • Patent number: 5881827
    Abstract: Extendable bit teeth are supported by the guide grooves formed on the end face at the point of a bit body in such a manner as to be slidable. The extendable bit teeth slide along the guide grooves in an excavating direction to thereby project from the end face at the point of the bit body. The extendable bit teeth slide in an opposite direction to the excavating direction to project from the outer periphery of the point of the bit body. Since the extendable bit teeth are pressed against the ground during excavation, the extendable bit teeth projects from the outer periphery of the point of the bit body so that the bit gauge can be extended, and most of the excavation hole is excavated by the bit body.

  • Patent number: 4760888
    Abstract: A drill bit for core boring of the type provided with a multi-layered bit head, so constructed that when the blades of the upper-layered bit head have become worn out, it is possible to easily withdraw them without removing the bit from the bore. The core boring operation is then continued without delay by using the blades of the newly exposed lower-layered bit head. The drill bit is also so constructed that it is possible to eliminate any displacement of the upper layer blades from their fitted position on the blades of the lower layer blades during drilling by using the upper layer blades and at the same time, it is possible to easily disengage the engagement between the bit body and the upper layer blades when the upper layer blades have become worn out.

  • Patent number: 4651837
    Abstract: A rotary well-drilling bit lowered through a drill string to a special orienting, positioning and aligning sub attached to the bottom of the drill string with the aid of mud pressure with the bit approximately 90.degree. from its normal operating position. The drill bit is prepositioned before entering the drill string and utilizes a drill bit positioning means to properly orient and position the drill bit at the bottom of the borehole. Once properly positioned and oriented, a wireline attached motor turns an assembly shaft which raises the drill bit into its bit receptacle. Removal of the drill bit is accomplished by relowering the wireline attached motor and turning the assembly shaft to loosen the shaft from the drill bit and raising the wireline, wireline motor, assembly shaft and drill bit through the drill string.

  • Patent number: 4470470
    Abstract: A boring apparatus comprises a drill pipe for being placed underground, an outer tube insertable into the drill pipe, and an inner tube axially movably inserted in the outer tube. The inner tube is locked against relative movement with respect to the drill pipe while being allowed to rotate therewith when locking members mounted on the inner tube partly project through locking member control windows in the outer tube into recesses defined in an inner surface of the drill pipe. An inner cutter and outer cutters mounted on a lower end of the inner tube can project beyond a lower end of the drill pipe, with the lowermost ends of the outer cutters being held in a projecting position radially outwardly of a circumferential surface of the drill pipe. When so positioned, the outer cutters are disposed more underground i.e., axially further away from the lower end of the drill pipe, than the inner cutter.
