A riser having a riser body having an interior surface, an exterior surface, and two spaced-apart ends, at least one identification assembly on the riser body, the identification assembly having an assembly body and a wave energizable apparatus in the body, the assembly body having an interior surface, an exterior surface, and a channel therethrough in which is positioned part of the riser body, the assembly body releasably secured on the riser body, and the wave energizable apparatus positioned within the assembly body. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 C.F.R. 1.72(b).

Drilling rig riser identification apparatus

Generally, the subject matter disclosed herein is directed to devices and methods for energizing and detecting a wave-energizable apparatus on an item movable with respect to a working surface of a drilling rig. One illustrative device disclosed herein includes at least one mat adapted to be positioned on a working surface of a drilling rig and a plurality of spaced-apart energizing apparatuses operatively coupled to the at least one mat. Additionally, each of the plurality of spaced apart energizing apparatuses of the disclosed device is adapted to energize a wave-energizable apparatus attached to an item that is movable adjacent to the mat and relative to the working surface.

Drilling rigs with apparatus identification systems and methods

A link member (e.g. a chain link or an elevator link) having a body, the body having two spaced-apart ends, wave-energizable apparatus (one or more) on the link body, and, in one aspect, a wrap or wraps securing the wave-energizable apparatus to the link. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 C.F.R. 1.72(b).

Chain with identification apparatus

An item (e.g. a drill bit) handling method, the item for use in a well operation, the method including producing information about an item used for a specific well task, the information including design information and intended use information, producing an item identification specific to the item, associating the information with the item identification producing thereby an information package, installing the information package in at least one wave-energizable apparatus, and applying the at least one wave-energizable apparatus to the item.

Systems and methods for monitored drilling

A screen apparatus, which in certain aspects is a screen apparatus having a support, screening material on the support, and energizable identification apparatus on (exteriorly, interiorly, and/or within) the support for identifying the screen apparatus; a vibratory separator with such a screen apparatus; and a vibratory separator or shaker with energizable identification apparatus.

Shale shakers and screens with identification apparatuses

A member having a body, the body having two spaced-apart ends, wave energizable identification apparatus which, in one aspect, is radio frequency identification apparatus with integrated circuit apparatus and antenna apparatus on the exterior of the body, and encasement structure encasing the identification apparatus, the encasement structure, in certain aspects, including one or a plurality of layers of heat resistant material and, in certain aspects, at least one layer of heat resistant material, and methods for producing such a member.

Apparatus identification systems and methods

A system for measuring inner diameter of a tubular, e.g., but not limited to, a riser or a pipe, the system including at least one linear distance measuring device movable through a hollow tubular, a main body also movable through said tubular, the at least one linear distance measuring device mounted on the main body, and the at least one linear distance measuring device for producing a measurement signal indicative of a measurement of inner diameter of the tubular.

Riser and tubular inspection systems

A system for measuring diameter (inner and/or outer) of a tubular, the system in at least certain aspects including at least one linear distance measuring device with respect to which a tubular to be measured is movable, the at least one linear distance measuring device including a detector for detecting a surface of the tubular, the detector movably mounted to mount apparatus, the detector movable longitudinally along the surface of the tubular and movable axially in response to variation in diameter of the tubular, a rotatable head rotatable with respect to the tubular either outside of it or within it, the mount apparatus secured to the rotatable head, at least one signal production apparatus secured to the mount apparatus or head, and in communication with the linear distance measuring device, the at least one signal production apparatus for producing a signal indicative of distance between said detector and a known point, and transmitting apparatus for transmitting said signals to processing equipment for determining diameter of the tubular; and in certain aspects the linear distance measuring device is a laser device, electronic measurement device, acoustic measurement device, infrared measurement device, or linear variable differential transformer device.

Tubular ovality testing

A testing method and apparatus detects magnetic discontinuities in a sample of magnetizable material. The apparatus may include an electric motor, a transmission, driven transport wheels, and non-driven transport wheels. Further, the apparatus includes a magnetizing device for inducing a magnetic field in the sample. A sensor unit detects magnetic stray flux from the magnetic field induced in the sample and converts the detected magnetic stray flux into a signal for processing by a signal processor.
