Abstract: A system or apparatus for use in downhole communication or detection comprises a downhole arrangement defining a throughbore and primary and secondary elements. One of the primary and secondary elements is provided on the downhole arrangement and the other of the primary and secondary elements is provided in the throughbore. The primary and secondary elements are configurable for coupling of an electromagnetic field therebetween. The primary or secondary element which is provided in the throughbore may be provided on a tool such as a shifting tool which is deployable through the throughbore. The secondary element may be configured to provide the electromagnetic field coupled between the first and second elements with one or more characteristic features. The system may be configured for use, in particular though not exclusively, for communicating information to and/or from a downhole tool in an oil or gas well.

Abstract: A loop antenna assembly is provided that can include a loop antenna with one of more magnet wires encased in a non-magnetic flexible sheath and mounted to a transceiver block that is mountable to a tool body, where the loop antenna can at least partially encircle the tool body. The loop antenna can include a plurality of magnet wires each individually encased in the sheath, with a metal adaptor attached to each end. The magnet wire can be coated with thin insulation, thin enamel insulation, and/or a polymer film. A plane of the loop antenna can be perpendicular relative to the longitudinal axis or at an obtuse angle relative to the longitudinal axis. A non-magnetic locating ring positioned in the loop antenna assembly can secure the loop antenna of the assembly about the tool body.

Abstract: A pipe has a longitudinal axis. A flex board extends along the longitudinal axis within the pipe and curls around the longitudinal axis. A cross-section of the flex board perpendicular to the longitudinal axis has a flex-board curve shape that has a first section on a first side of a line perpendicular to the longitudinal axis and a second section on a second side of the line perpendicular to the longitudinal axis. The first section has a first section shape and the second section has a second section shape. A first conductive stripe is coupled to the flex board, extends along the longitudinal axis, and follows the contour of the first section of the flex board. A second conductive stripe is coupled to the flex board, extends along the longitudinal axis, and follows the contour of the second section of the flex board.

Abstract: A drill bit analysis and optimization system for use in a wellbore is provided. The system includes a drill bit including a cutter, a sensor that collects a data signal on a surface of the drill bit proximate to the cutter, and a signal processor unit that receives the data signal from the sensor and receives the expected drilling properties from the data reservoir. The processor analyzes the data signal to detect a resistivity profile from the sensor through a formation and optimizes a drilling parameter by comparing actual drilling properties with expected drilling properties.

Abstract: Described are systems, devices, and methods for processing Eddy-current response signals acquired in a set of multiple nested pipes, such as, e.g., nested casing strings within a completed wellbore. In various embodiments, time boundaries between time slots within the Eddy-current response signals are determined adaptively based on an input response signal specific to the nested pipes (e.g., one of the measured signals itself). Additional embodiments are disclosed.

Abstract: Apparatus and methods to image pipes of a multi-pipe structure can be implemented in a variety of applications. The multi-pipe structure may be associated with a well site, such as a multi-casing structure for a production well. Individual pipes of the multi-pipe structure may be investigated in a multi-stage process using delta-like responses, where previous stages provide inputs to subsequent stages. The results of multi-stage processing can be used to image defects in the multi-pipe structure.

Abstract: Systems, computer-implemented methods, and non-transitory computer-readable medium having a stored computer program provide characterization of multiphase fluid flow (MPF) using approximate entropy calculation techniques to enhance measuring and monitoring of a flow regime in a segment of pipe for hydrocarbon-production operations. The systems and methods can be optimized using principal component analysis.

Abstract: NMR properties of earth formations are determined using a logging device movable in a borehole. The logging device includes a magnet assembly to generate a static magnetic field and an antenna expandable from the surface of the magnet assembly into the borehole toward the borehole wall to increase the magnetic dipole moment of the antenna. The logging device can be lowered or raised through a drill pipe with the magnet assembly being configured to generate no magnetic field while the device is conveyed within the drill pipe. The logging device may also include a side-looking sensor to acquire fast relaxation component of the NMR signals.

Abstract: A method for signal communication between a well drilling instrument and the Earths surface includes generating an electromagnetic field in an instrument disposed in drill string used to drill a wellbore. The electromagnetic field includes encoded measurements from at least one sensor associated with the instrument. A signal corresponding to an amplitude and/or phase of the electromagnetic field is measured between the drill string and a surface electrode when the drill string is substantially electrically isolated from a well casing. A signal corresponding to the amplitude and/or phase is measured between the casing and a surface electrode when the casing and the drill string are in electrical contact with each other.
