Abstract
A method is provided for determining whether a change in a subsurface formation, such as fractures produced within the earth during a fracturing process, has reached and/or crossed a given boundary. The method provides near real time assessment of fracture propagation that can be used to guide a fracturing, particularly a hydrofacturing process.
