Abstract: A drilling assembly includes a first tubular member supporting a first transmitter antenna and a steering assembly located beneath the first tubular member. The drilling assembly also includes an earth boring device comprising a drill bit. The drill bit has a body member, a bottommost surface and a gage surface at a stabilizing section of the drill bit. The earth boring device is supported beneath the steering assembly. The earth boring device includes a second transmitter/receiver antenna supported in spaced relation to the first transmitter antenna and within 36 inches of the bottommost surface of the drill bit, and at least one electrode generally at an outer surface of the stabilizing section of the drill bit.

Abstract: Wellbore tools may use carbon nanoforests to reduce the access of abrasive particles to compressible sealing elements of joints of the wellbore tool. In some instances, a wellbore tool may include a joint comprising two elements having opposing mating surfaces that define a gap; a compressible sealing element arranged between the opposing mating surfaces and configured to seal a portion of the gap, thereby defining a sealed segment and an unsealed segment of the gap; and at least one carbon nanoforest disposed within at least a portion of the unsealed segment and coupled to at least one of the opposing mating surfaces.

Abstract: During drilling of an earth borehole, resistance measurements may be made at the drill bit through use of a bottom hole assembly that includes a drill bit having a sensor, such as an electrode, located generally at an exterior surface of the drill bit. The current will be induced in the formation from multiple transmitters, at least one of which will be supported on, or very close to the drill bit. Connection mechanisms are described that enable the releasable engagement of electrical conductors to circuitry within the drill bits. The obtained resistivity measurements at the drill bit can be used for many purposes, including formation imaging and geosteering of the drilling operation.

Abstract: Of the many embodiments provided, one embodiment is a drill bit mold assembly comprising: a mold having a bottom and at least one side; a core centrally disposed within the mold; and a filter disposed above the bottom of the mold and within a space formed between the at least one side of the mold and the core.

Abstract: A container is provided for packaging, shipping, storing and presenting a rotary drill bit. The container may be used with fixed cutter drill bits or roller cone drill bits. A wide variety of tools and accessory components may be disposed within the container. A bit breaker may also be attached to one end of the container using a bit breaker adapter. Bit breakers for two different sizes of rotary drill bits may be releasably engaged with a container using the same bit breaker adapter.

Abstract: A method for recycling rail is provided wherein the rail is heated, and then slit into two pieces. The two pieces are passed through a single mill pass line such that each piece of the rail is deformed to have a generally uniform shape.

Abstract: A matrix drill bit and method of manufacturing a matrix bit body from a composite of matrix materials is disclosed. Two or more different types of matrix materials may be used to form a composite matrix bit body. A first matrix material may be selected to provide optimum fracture resistance (toughness) and optimum erosion, abrasion and wear resistance for portions of a matrix bit body such as cutter sockets, cutting structures, blades, junk slots and other portions of the bit body associated with engaging and removing formation materials. A second matrix material may be selected to provide desired infiltration of hot, liquid binder material with the first matrix material to form a solid, coherent, composite matrix bit body.

Abstract: Acoustic signals generated by drilling a bore hole with a drill bit are received at sensors placed in the drill string. The acoustic signals received by the sensors are processed, e.g. using a Fourier transform, and a characteristic of the acoustic signals is used to identify lithology, rock strength, presence of oil, presence of gas, change in lithology, or the like.
