摘要： In some embodiments, a method for reducing magnetic debris accumulation on a downhole sensor within a tubular conveyed in a borehole comprises supplying a voltage to temporarily neutralize a magnetic field of a permanent electromagnet proximate to the downhole sensor and removing magnetic debris on the downhole sensor via a flow of a first fluid in the tubular while the magnetic field is neutralized.

摘要： A sealed enclosure can include a glass portion that can be positioned with respect to an electromagnetic component that is in an area defined by the sealed enclosure. The enclosure can prevent fluid from a wellbore environment from contacting the electromagnetic component and to allow the electromagnetic component to wirelessly communicate with a component external to the sealed enclosure. A second portion interfaces with the glass portion for preventing the fluid from the wellbore environment from contacting the electromagnetic component.

摘要： A downhole gauge for recording data during well treatment comprised of an outer housing having pressure ports, and a pressure-tight inner housing wherein a plurality of sensors, a power source, and a memory configured to store measured data are housed. The outer housing consists of a first section having external pressure ports with a spherical outer surface and a cylindrical inner surface with a hollow lattice structure within, and a second half having no ports with a spherical outer surface and a conical inner surface with an internal hollow lattice structure within. The inner housing consists of a cylindrical body comprised of one section having no ports, and a second section having one port wherein a plurality of sensors can be affixed. The inner housing sections are releasably coupled to form a pressure-tight seal. Further, the outer housing sections are releasably coupled and enclose the inner housing therein.

摘要： A compact instrumented downhole coupling that includes a carrier and a set of sensors and electronics that are installed within the carrier. The carrier is a tubular structure having couplings at each end and a bore therethrough, where cavities are formed in the carrier wall. The cavities are open to a side facing away from the carrier's bore, where sensors placed in the cavities are accessible through the side opening. Electrical connections to the sensors are made via the side opening, and a clamp can be installed in the cavities via the side opening, the clamp holding the sensors securely in position within the cavities. After installation of the sensors in the cavities, plates are welded over the side opening to form an enclosure for the sensors in the carrier wall.

摘要： Communication networks, relay nodes for communication networks, and methods of transmitting data among a plurality of relay nodes utilizing non-dispersive guided acoustic waves are disclosed herein. The communication networks include an elongate tubular body and a wireless data transmission network including a plurality of relay nodes. The relay nodes include an electro-acoustic transmitter array and an electro-acoustic receiver. The methods include inducing a first acoustic wave within the elongate tubular body with a first relay node, conveying the first acoustic wave along the elongate tubular body to a second relay node, and receiving the first acoustic wave with the second relay node. The methods further include inducing a second acoustic wave within the elongate tubular body with the second relay node, conveying the second acoustic wave along the elongate tubular body to a third relay node, and receiving the second acoustic wave with the third relay node.

摘要： A drilling system includes an internal assembly comprising a chassis, a flow diverter, or both, and a strain gauge coupled to the chassis, the flow diverter, or both, in which the strain gauge is configured to output a signal associated with a strain deformation of the internal assembly. The drilling system also includes a drill collar coupled to the internal assembly, in which the internal assembly extends along the drill collar, and the drill collar encloses the internal assembly of the internal assembly such that a strain deformation of the drill collar causes the strain deformation of the internal assembly.
