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

Patent ·
OSTI ID:1373741

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.
