Abstract
The methods described are for determining distribution, orientation and dimensions of networks of hydraulically-induced fractures within a subterranean formation containing fluids. Detectable signals are generated by particles introduced into the fractures. In an exemplary method proppant-like particles are positioned in the formation during fracturing and allowed to generate a signal during or after fracturing activity. The detectable signals generated by the proppant-like particles are used to map fracture space.
