    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: Apparatus and methods for testing inductively coupled downhole systems are described. An example inductive coupler assembly for use in a wellbore includes an inductive coupler fixed to a completion in the wellbore, a drill pipe, a portion of which is to be located adjacent to the inductive coupler, and a sleeve surrounding the portion of the drill pipe to reduce a reluctance of a magnetic circuit including the inductive coupler.

    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.

    CPC classification number: E21B17/028

    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.
