1. A method for evaluating and measuring the geometry of a fracture comprising:
a. injecting a proppant into the fracture, wherein at least a portion of the proppant is electrically reactive, wherein the proppant may be coated with an electrically reactive coating or contains particles of electrically reactive material, wherein the proppant reacts to an electrically active liquid; b. exposing the proppant to the electrically active liquid creating an electrical signal, wherein the liquid is natural brine, drilling fluids, fresh water or combinations thereof; c. detecting the electrical signal with at least one sensor; d. converting the electrical signal into a voltage signal compatible with geophysical survey equipment; and e. evaluating and measuring the geometry of the fracture using the data from step (d). |
