Abstract
The methods of evaluating a geometry of a hydraulic fracture in a rock formation penetrated by a borehole comprises the steps of measuring the values of electric or magnetic fields, or both electric and magnetic fields generated due to the electrokinetic effect by the flow of an electrolyte-based fracturing fluid from the borehole into the fracture and from the fracture into the formation or by the reverse flow of the fluid from the rock formation and from the fracture into the borehole and determining the geometry of the fracture from the measured values. The methods may provide for varying the injection pressure, varying the value of the electrokinetic coupling coefficient of the fracturing fluid or applying at least one pressure pulse of a given magnitude to the fracturing fluid.
