摘要： A tool, method, and system for evaluating integrity of one or more tubing strings in a wellbore with multiple tubing strings. The tool, method, and system may include a magnetic source that can radiate the tubing strings with at least one primary electromagnetic field, a sensor that can detect a secondary magnetic field produced by induced eddy currents in the tubing strings, and a magnetizer that can magnetize a portion of an inner-most tubing string in the wellbore such that the portion of the inner-most tubing string has an increased magnetic transparency to the primary and secondary fields when the magnetizer is enabled, where the magnetizer can include a static magnetic source, and a structure that magnetically couples the static magnetic source to the inner-most tubing string.

摘要： A system and method to actuate a downhole tool, where the tool can include a body, a closure member and a degradable actuation ring. A profile of the actuation ring can be configured to engage an actuation tool (e.g. shifting tool, ball drop, dart, plug, etc.) used to displace the activation ring via the engagement and thereby displacing the closure member to a different position. The degradable actuation ring can be degraded by an agent downhole to degrade and/or remove the actuation ring from the downhole tool thereby providing an increased clearance through the tool.

摘要： A system and method for evaluating integrity of cement in a wellbore with multiple casing strings. The system and method may include at least one source that can emit a field of photons, and at least one photon detector spaced away from the source by a first distance that configures the tool to measure cement integrity in a first annulus, by a portion of the source photons being scattered back to the first detector which can produce photon count rates based on energy levels of received photons. Integrity of cement in the first annulus can be determined by the photon count rates. A second detector spaced a second distance from the source can be included and can measure cement integrity in a second annulus that is radially outside the first annulus by producing photon count rates for photons received from the second annulus.

摘要： Various embodiments include apparatus and methods implemented to take into consideration gauge length in optical measurements. In an embodiment, systems and methods are implemented to interrogate an optical fiber disposed in a wellbore, where the optical fiber is subjected to seismic waves, and to generate a seismic wavefield free of gauge length effect and/or to generate a prediction of a seismic wavefield of arbitrary gauge length, based on attenuation factors of a plurality of wavefields acquired from interrogating the optical fiber. In an embodiment, systems and methods are implemented to interrogate an optical fiber disposed in a wellbore, where the optical fiber is subjected to seismic waves, and to convert a seismic wavefield associated with a first gauge length to a seismic wavefield associated with a different gauge length that is a multiple of the first gauge length. Additional apparatus, systems, and methods are disclosed.

摘要： A tool, system, and method for reentry access into a lateral wellbore. The tool, utilized in the system and the method, can include a body with an internal flow passage, an inflatable bladder disposed along an exterior portion of the body, and a flow restrictor that can partially restrict fluid flow through the internal flow passage and create a pressure differential across the tool when fluid pressure rises at an inlet of the internal flow passage. The pressure differential can cause inflation of the inflatable bladder and a surface of the inflatable bladder can be extended radially outward from the body in response to the inflation, where the extended surface can push the tool away from a wall of a main wellbore toward an opposite wall of the main wellbore and divert the tool into a lateral wellbore.

摘要： A system for providing autonomous flow control of a fluid from a wellbore to an interior of a tubing string by using a variable flow resistance system. The system can include a body, with a chamber that can be configured to induce rotational flow in a fluid that flows through the chamber. The chamber can include an inlet for fluid entering the chamber and an outlet for fluid exiting the chamber. A cross-sectional area of the chamber can be reduced along a central axis of the chamber toward the outlet, with the cross-sectional area being perpendicular to a central axis. A well screen assembly may utilize one or more of the variable flow resistance systems to provide a determined flow resistance and/or flow rate of the fluid through the screen assembly.

The optical detection system can further include an optical detector comprising a single]photon detector (SPD) for detecting the reflected measurement signal received over the fiber optic cable. The optical detection system can further include a housing for enclosing the optical detector and to optically shield the optical detector, the housing including an aperture for passage of the fiber optic cable.
