An electrical assembly of a downhole tool utilized within a wellbore extending into a subterranean formation. The electrical assembly includes a housing substantially formed of thermoplastic material, an electronic device sealed within the housing, and an electrode or sensor sealingly embedded within a wall of the housing and electrically connected with the electronic device.

Encapsulated sensors and electronics

Systems and methods for reducing torque on a rotating downhole logging tool are provided. In one embodiment, a downhole logging tool is provided. The downhole logging tool may include a support element, which may include a hollow cavity. The support element may be configured to rotate about an axis when the support element is inserted in a well, and the hollow cavity may be configured to permit fluid flow through the support element when the support element is in the well. Furthermore, the downhole logging tool may include a first fairing portion, which may include a first sensor to obtain measurements in the well. Additionally, the first fairing portion may be configured to form a revolution surface associated with a portion of the support element.

A tool system for monitoring a flow of liquid within a borehole. The tool system comprises a plurality of tools disposed on a longitudinal axis of the tool system. The plurality of tools comprises at least a first injector tool for ejecting in the borehole a tracer and a detector tool to detect the ejected tracer. The tool system further comprises a standard digital bus traversing at least a portion of each tool of the plurality of tools. The standard digital bus allows a communication between each tool of the plurality of tools.

Tracer injector tool for well investigation

An electromagnetic imaging apparatus and method for electromagnetically measuring physical parameters of a pipe CJ, CC by means of a plurality of measuring arrangement ZMA, MCMA, MonMa, ImMA comprising a plurality of transmitter coil ZTX, LFTX, DTX and a plurality of receiver coil ZRX, ZR, MRX, MC, PRX, PRX, PRX, PRX, PRX, PRX, PRX, PRX, PRX, PRX, PRX, PRX, PRX, PRX, PRX, PRX, PRX, PRX, the transmitter coils and receiver coils being associated so as to form the plurality of measuring arrangement, the plurality of measuring arrangement being adapted to be positioned into the pipe and displaced through the pipe, the physical parameters being measured for a plurality of position along the pipe.

Electromagnetic imaging method and device

An apparatus for measuring an internal dimension of a well-bore comprising a tool adapted to be positioned inside the well bore. The tool comprises an optical caliper comprising an optical sensor providing a response correlated to the internal dimension of the well bore, the optical sensor being coupled to an optical fiber.
