Abstract: A carrier device is provided for temporary installation downhole in a well. The carrier device is a robust device that is divided by a pressure bulkhead into a first section having an inductive coupler, power electronics, and a telemetry unit, typically all formed using multi-chip-module type electronics, and a second section with at least one test device typically using printed circuit board technology that may include sensors or transducers coupled to a communications bus and/or a power line that extends to the first section via the pressure bulkhead. The carrier further includes a mechanism that permits the carrier to be pulled out of the wellbore, and may include a mechanical locating element, typically adjacent the inductive coupler that permits the carrier to be located in the wellbore so that the inductive coupler will be located adjacent an inductive coupler in, on, or behind a liner or casing of the wellbore.

Abstract: A technique facilitates verification of the integrity of a lower completion prior to deployment of a corresponding upper completion. A lower completion is initially deployed downhole into a wellbore and comprises a plurality of functional components, such as a sensor, a communication system, a flow control system, and/or other functional components. A service tool system is removably deployed into the wellbore and comprises a service tool with an interface which interacts with the lower completion. The interface enables verification of the integrity, e.g. functionality, of various functional components of the lower completion without the use of an additional communication line, e.g. power cable, routed separately to the lower completion.

Abstract: A redundant trigger section that actuates a device between operational positions in response to a controlled signal includes a housing including an internal through passage and a plurality of chambers formed in a wall of the housing. a pilot piston disposed within the internal through passage, an actuating piston connected to the pilot piston, and a plurality of triggers connected to the actuating piston. Upon receipt of the controlled signal by a first tubing pressure chamber of the plurality of chambers, at least one trigger of the plurality of triggers activates the actuating piston, which pushes the pilot piston within the internal through passage from an initial position to a final position.

Abstract: A technique facilitates formation of secure connections for use in downhole environments. According to an embodiment, a connector may be constructed as a dry mate connector which provides both a sealed connection and a connection able to withstand a predetermined tensile loading. The connector comprises connector ends combined with an outer connector housing. Additionally, the connector comprises a shape memory alloy sealing system which may be activated to form a secure seal with a corresponding cable or other component feature. The connector also comprises a shape memory alloy retainer system which may be activated to securely grip the corresponding cable or other component feature so as to withstand substantial tensile loading acting on the corresponding cable or other component feature.

Abstract: A technique facilitates evaluation of a fluid flowing through a tubing and includes at least one sensor deployed along an interior of the tubing. Each sensor comprises a plurality of electrodes and insulation material disposed between the electrodes to isolate the electrodes from each other and to facilitate resistivity measurements. The plurality of electrodes comprises electrodes for emitting an electric current and for monitoring voltage so as to enable resistivity measurements with respect to fluid flowing through the tubing. The resistivity measurements may be used to determine a constituent fraction, e.g. a water fraction, of the fluid flowing through the tubing.

Abstract: A multiphase flowmeter for detection of fluid flow by monitoring of vortex frequency or perturbation time of flight. The flowmeter includes a bluff body to facilitate formation of vortices during a consistent phase of a flowing fluid. Thus, monitoring frequency of the vortices may be employed to ascertain flowrate. Further, the bluff body may also facilitate formation of perturbations during transitioning phase of the fluid and include perturbation sensors at multiple known locations along the flow-path. Thus, analysis of perturbation detection times at the different locations may be used to ascertain flowrate even in the absence of vortices.
