Electrical methods fracture detection via 4D techniques
Abstract:
Method for acquiring and evaluating geometry of a well includes deploying at least one grid of geophysical sensors, wherein the at least one grid of the sensors is deployed in a 2D or 3D configuration; acquiring an initial geophysical survey of geophysical parameters of the well; fracturing the well creating a fracture while simultaneously; injecting an electrically active proppant into the fracture, wherein the electrically active proppant is injected into the fracture during fracturing, after fracturing or during and after fracturing; continuously acquiring a geophysical survey of geophysical parameters of the well during the fracturing; and acquiring a final geophysical survey of geophysical parameters of the fracture upon completion of the fracturing.
