Abstract: A ruggedized bidirectional cutting system with an outer wear band having a first blade-free fitting section engaging within the drill string and a first cutting section integral with the first blade-free fitting section. The first cutting section has a plurality of blades, each blade with two cutting portions extending at defined cutting angles and a blade cutting portion extending at a third angle from the longitudinal axis different from the first and second angles. Each blade has cutting inserts. A plurality of flutes are formed between pairs of blades to stabilizes and protects bottom hole equipment while a wellbore completes directional drilling objectives.

Abstract: Disclosed herein are methods of accurately measuring carcinoembryonic antigen in a biological sample and methods of identifying and treating a mucinous cyst in a subject.

Abstract: A stress-free centralizer system for wellbore tubulars having a centralizer portion with hollow vanes or solid vanes. An injectable material can be configured to harden at ambient or elevated temperatures and installed into the hollow vanes while coating a portion of the inner surface of the centralizer portion. Alternatively, a swellable encapsulation and shape shifting material can be used instead of the injectable material. Additionally, primers and adhesives can be used with the centralizer portion. Both materials when hardened or swollen can be configured to withstand temperatures and pressures within a wellbore for twenty-four hours without melting or degrading. The centralizer portion can simultaneously prevent axial movement and rotational movement while installed on the wellbore tubular, distribute load evenly around the centralizer portion, and provide cathodic protection to the wellbore tubular without using a stop collar with screws.

Abstract: A drilling rig has a bidirectional eccentric stabilizer for use in a wellbore. The bidirectional eccentric stabilizer is coupled between a drill string and a bottom hole assembly. The bidirectional eccentric stabilizer has a shaft connected between a first shaft end and a second shaft end, an annulus formed longitudinally through the shaft and a cutting portion formed on an outer surface of the shaft. The cutting portion has a first cutting portion, a second cutting portion, a plurality of helical blades, a plurality of flutes, a plurality of cutting nodes, and a plurality of impact arrestors. The bidirectional eccentric stabilizer has a center of eccentric rotation which is offset from the longitudinal axis of the shaft, enabling the bidirectional eccentric stabilizer to form a larger wellbore than a drill bit on the bottom hole assembly and a larger diameter wellbore than originally drilled by the drill bit.

Abstract: A field created integral electrically isolated centralizer and swell packer system for wellbore tubulars having in series over the wellbore tubular, a first end ring, a swell packer portion over a first and second primer optionally with cured resin, a second end ring, wherein the end rings inhibit axial movement of the swell packer portion. Integral with the swell packer portion an electrically isolating centralizer; a cured resin bonded to the wellbore tubular filling all hollow spaces of the centralizer portion integrally forming a high strength bond, while excluding bonding to the first and second end rings, the cured resin configured to cure to a hardness of at least 50 shore A and withstand temperatures and pressures within a wellbore for at least twenty-four hours without melting, while specifically excluding a sand screen.

Abstract: An orienting tool for use in wells can include a flow control device which controls flow between an interior and an exterior of a body of the tool to thereby transmit a signal indicative of an orientation of the body, the flow control device being outwardly extendable relative to the body. A method of orienting a structure in a well can include transmitting at least one signal from an orienting tool, the signal being indicative of an orientation of the orienting tool, and displacing a housing of the tool outward relative to a generally tubular body of the tool. A well system can include an orienting tool connected to a structure and positioned in a wellbore, the tool including a housing which is outwardly extendable relative to a generally tubular body, the tool being configured to transmit at least one signal indicative of an orientation of the structure.

Abstract: An isolation liner incorporating a drill pipe and a swell packer, the swell packer configured to simultaneously cut and seals a wellbore, or slide down and seal a wellbore having a swellable section and a pair of end rings. The end rings couple the cylindrical body to the swellable wellbore packer section. Each end ring forms an annular abutment surface that cooperates with the swellable member to inhibit axial movement of the swellable member on the substantially cylindrical body. On each end ring, at least one diamond cutter insert, polyamide button, and/or tungsten carbide blocks is installed circumferentially and spaced apart symmetrically or near-symmetrically on the end ring.

Abstract: A drilling rig with mini-stabilizer tool for connecting to a measurement while drilling (MWD) system. The mini-stabilizer tool centralizes components in the wellbore for a more accurate measurement to protect measurement while drilling components from wear on shoulders of the measurement while drilling components. The mini-stabilizer tool accomplishes wear prevention by positioning the measurement while drilling components away from edges of the wellbore.
