A composite strip which extends in a main direction between first and second ends and which comprises a main strip comprising first fibres embedded in a matrix. The first fibres are made of carbon, an electrically conducting material, and the matrix is made up of at least one polymer. The composite strip further comprises a junction layer formed of an electrically conducting junction material. The junction layer is placed on the main strip.

Composite strip, and methods for forming a junction between two conduits

An electrical heating device comprising a support and a heating layer made of carbon fibre composite on the support mid connected to an electrical power supply to warm the device. The heating layer has a volume which comprises an electrically conducting circuit part which extends along at least one continuous line, and an electrically non-conducting insulation part which fills the remainder of the volume of the heating layer.

Electric heating device

A method for forming an electrical connection in a pipe for transporting a fluid. The pipe comprises an internal hollow tube and a heating layer comprising first fibers made of carbon. There are performed a groove-formation step in which a groove is formed in the heating layer, an interface-preparation step in which a junction layer is placed on the heating layer of the groove, and a placement step in which a connection strip comprising second fibers formed of a second electrically conducting material is wound on the junction layer.

Method for forming an electrical connection

A device is proposed for fracturing a geological hydrocarbon reservoir, including two packers defining a confined space therebetween in a well drilled in the reservoir, an apparatus for regulating the temperature of a fluid in the confined space, a pair of two electrodes arranged in the confined space, and an electric circuit to generate an electric arc between the two electrodes. The circuit includes at least one voltage source connected to the electrodes and an inductor coil between the voltage source and one of the two electrodes. This allows improved fracturing of the reservoir.

Electric fracturing of a reservoir

A method is provided for fracturing a geological hydrocarbon reservoir, including the static fracturing of the reservoir by hydraulic pressure, and the electrical fracturing of the reservoir by generating an electric arc in a well drilled into the reservoir. This enables the improved fracturing of the reservoir.

Electrical and static fracturing of a reservoir

A device is provided for fracturing a geological hydrocarbon reservoir including two packers defining between them a confined space in a well drilled in the reservoir; a pump for increasing the pressure of a fluid in the confined space; an apparatus for heating the fluid; at least one pair of two electrodes arranged in the confined space; and an electric circuit for generating an electric arc between the two electrodes, the circuit including at least one voltage source connected to the electrodes and an inductance between the voltage source and one of the two electrodes. The device permits improved fracturing of the reservoir.
