    摘要： A tubular string having a box end and pin end coupled to one another with a threaded attachment and a coupling assembly. The coupling assembly includes an annular outer thrust ring having an axial end abutting a shoulder on a terminal end of the box end. Included with the coupling assembly is an inner thrust ring, which is also annular, and which has an end that axially abuts a shoulder formed along an outer surface of the pin end. An alternate type of the inner thrust ring is made up of two separate semi-circular members that circumscribe the pin end when positioned in the recess so their arcuate ends adjoin. The inner thrust ring inserts into the outer thrust ring, and has a radial surface on its outer circumference that lands on a shoulder formed along an inner circumference of the outer thrust ring.

    摘要： Proteins with antibacterial properties may be used in additive compositions, fluid compositions, and methods for decreasing or removing sulfur-containing compounds and/or acid-containing compounds from recovered downhole fluids and/or the subterranean reservoir wellbore from which the downhole fluid was recovered. The fluid composition may include at least protein and a base fluid. The protein(s) may be or include a labiase, a lysozyme, a lysostaphin, a hexose oxidase, a cecropin, a thermolysin, a serine protease, a cysteine protease, and combinations thereof. The base fluid may be or include a drilling fluid, a servicing fluid, a production fluid, a completion fluid, an injection fluid, a refinery fluids, and combinations thereof.

    摘要： A method for deploying a fiber optic line from a surface to a desired location in a wellbore includes the steps of identifying a heater cable deployed in the wellbore, where the heater cable includes one or more conductors and a first capillary tube. The method continues with the step of loading a terminal end of the fiber optic line into the first capillary tube from the surface. Next, the method includes the step of pumping a working fluid into the first capillary tube from the surface to inject the fiber optic line through a portion of the first capillary tube. The method concludes with the step of stopping the injection of the fiber optic line when the terminal end of the fiber optic line reaches the desired location in the wellbore.

    摘要： Systems and methods for measuring formation properties in downhole operations are provided. The systems and methods include generating, at a neutron source, neutrons that are emitted into a downhole formation (302), registering, at a detector, photons generated by chemical constituents of the downhole formation (304), measuring a response of the photons registered at the detector (306), transforming, with a computing system, the measured responses of the photons registered at the detector into thermal neutron capture probabilities (308), and transforming the thermal neutron capture probabilities into weight concentrations of the chemical constituents of the downhole formation (312).

    摘要： A pin whose movement triggers setting of the borehole tool, is initially held by a collet that is supported off a surrounding housing. A spring is supported off the pin and would push a housing that locks the collet to the pin axially to unsupport the collet but for the presence of a Kevlar® wire that has an associated heater. The wire pulls the housing that locks the collet against the spring bias and has an end attached to the pin. Melting the wire allows the spring to move the housing that traps the collet to the pin. At that point hydrostatic pressure can move the pin to either open a port on the borehole tool to set it hydrostatically or to move an actuation rod attached to the pin to set the borehole tool mechanically or with a combination of mechanical and hydraulic force.

    摘要： A method of estimating a parameter of an anomaly in an earth formation includes: disposing a measurement device at at least one measurement location, the measurement device including a frequency standard; estimating a frequency shift of a frequency standard due to a gravitational potential at at least one measurement location; and deriving a relationship between a mass and a depth of a formation anomaly at a distance to the at least one measurement location using the frequency shift.

    摘要： An operating system for a barrier valve or safety valve is responsive to increments in annulus or tubing pressure. An indexing device controls valves that selectively direct pressure applied to one side of an operating piston or the other for attaining the open and closed positions of the barrier valve. One such indexing device can be a j-slot. Other devices that operate a pair of hydraulic valves in tandem for pressure direction to one side of an actuation piston or another are contemplated. The system needs no electric power and there are no control lines needed to run below the production packer in the case of using annulus pressure to actuate the piston or at all if access to tubing pressure is provided from the vicinity of the barrier valve components.
