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 can include a shape memory alloy sealing system which may be activated to form a secure seal with a corresponding cable or other component feature.

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.

Inductive couplers for use in a downhole environment are described. An example inductive coupler for use in a downhole environment includes a body defining a cavity and magnetic material positioned in the cavity. The example inductive coupler also includes a coil adjacent the magnetic material, the coil formed with a number of turns of wire, and a first metal cover coupled to the body to enclose the cavity. The metal cover being electrically coupled to the body to form a substantially contiguous electrically conductive surface surrounding the cavity.

The invention relates to a device for integrating electrodes () characterizing the flow of a multiphase fluid in a tubing (). The device includes a tube section () made out of an electrically insulating material and bearing the electrodes on its external surface. A metal compensation sheath () encircles the section (), being separated from the latter by an insulating and incompressible fluid. An annular chamber () outside the sheath communicates with the inside of the tubing (). The sheath () is fixed on seal rings () inserted at the ends of the section (), by reinforcement for example.
