    Abstract: A technique facilitates use of an inductive coupler assembly with casing, e.g. well casing. An inductive coupler is formed as a female inductive coupler with an inductive coil. The inductive coupler is constructed for sliding movement along an exterior of the casing so that it may ultimately be positioned and secured at a suitable location along the casing. The inductive coupler is designed for connection with an electrical device, e.g. a sensor. The inductive coupler facilitates the transfer of sensor data and/or power signals across the casing. Signal transfer across the casing is further enabled by a male inductive coupler positioned within the casing at a location which allows it to cooperate with the exterior, female inductive coupler.

    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: An electronic trigger system includes a longitudinal housing including detection, electronics, and actuation sections disposed therein. The detection section includes a pressure sensor for receiving a predetermined pressure signal, and an electronic control board including at least one battery is disposed in the electronics section. The actuation section includes a prefill chamber, a setting piston disposed in the prefill chamber, an actuation device, an atmospheric chamber, and a pressure port. A predetermined amount of prefilled fluid at hydrostatic pressure is trapped between the setting piston and the actuation device in the prefill chamber. The actuation device isolates the prefilled fluid at hydrostatic pressure in the prefill chamber from the atmospheric chamber. Actuation occurs when, upon receipt of the predetermined pressure signal by the pressure sensor, the electronic control board transmits power to the actuation device, causing the prefilled fluid to flow through the actuation device and into the atmospheric chamber.

    Abstract: A sensor assembly for use with a completion disposable within a well extending through a reservoir. The sensor assembly may include a sensor cable and a plurality of vibration sensors. The sensor cable may include an outer liner made up of housing sections and sensor housing structures sealably connected to the housing sections and spaced apart longitudinally along a length of the sensor cable. The plurality of vibration sensors may be operable to measure a property related to a flow of fluid within the reservoir and each sensor of the plurality of vibration sensors may be disposed in a respective sensor housing structure.

    Abstract: A trigger system for use with a downhole tool. The trigger system may include a first housing forming a first pressure chamber at a first pressure and including a membrane positioned in a wall of the first housing, a piston disposed at least partially within the first housing and shiftable from an initial position to an actuated position to actuate the downhole tool, and a trigger. The trigger may include a second housing sealed against the first housing proximate the membrane to form a second pressure chamber at a second pressure and a rupturing member positioned within the second housing and operable to pierce the membrane to balance the pressures within the first housing and the second housing and shift the piston from the initial position to the actuated position.
