Electrofracturing test system and method of determining material characteristics of electrofractured material samples

DWPI Title: Device for electrofracturing material sample, has voltage source that is electrically coupled to material sample to provide voltage pulse across material sample, and gas measurement system that is fluidly coupled to material sample
Abstract: A device for electrofracturing a material sample and analyzing the material sample is disclosed. The device simulates an in situ electrofracturing environment so as to obtain electrofractured material characteristics representative of field applications while allowing permeability testing of the fractured sample under in situ conditions.
Use: Device for electrofracturing material sample.
Advantage: Provide a system and method for determining the characteristics of material electrofractured under in situ stress conditions typical of rock formations. Allow for the flow of a fluid through the sample before, during and/or after electrofracturing to measure in real time the permeability of the sample.
Novelty: The device (11) has pressure vessel (17) that is made up of an internal cavity, and a pressurized fluid supply system that is fluidly coupled to the internal cavity. A material sample is disposed within the internal cavity. A voltage source is electrically coupled to the material sample to provide a voltage pulse across the material sample, and a gas measurement system (15) is fluidly coupled to the material sample, in which the voltage source provides a pulse of between 150 Kilovolts and 1 megavolts.
