A first and a second substrate are bonded together to thereby form a unitary hybrid substrate. Each of the plurality of second electrodes is centered between each of the plurality of first and third electrodes, which leads to a bi-discharge source. The female receptacle may have a screw-style plunger, a sleeve-style plunger, or other means for applying pressure against the sleeves holding the prongs that are plugged into the receptacle. The module includes a motorized element disposed in the mounting box. According to the invention this fluid comprises a first viscoelastic surfactant and a second surfactant able to decompose under downhole conditions to release a compound itself able to reduce the viscosity of the aqueous viscoelastic fluid.
