Method to monitor reservoir fracture development and its geometry

摘要

Method to monitor reservoir fracture development and its geometry may find its application at oil and gas fields as well as in coal mining industry. The method provides injection of conductive fracturing fluid into the wellbore under pressure enabling to create a fracture in the formation and penetrate into it. At the stage corresponding to the end of the fracturing fluid charging a series of voltage pulses is applied to the fracturing fluid. In the well parameters of the electromagnetic field and/or acoustic signals resulting from applying the voltage pulses to the fracturing fluid are measured, and the fracture tip coordinates are determined.
