Patent number: 10215873Abstract: 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.Type: GrantFiled: August 19, 2013Date of Patent: February 26, 2019Assignee: Hallliburton Energy Services, Inc.Inventors: Lee J.

Patent number: 9500069Abstract: Methods for determining distribution, orientation and dimensions of networks of hydraulically-induced fractures within a subterranean formation containing fluids. Micro-seismic events are generated by particles introduced into the fractures which are capable of explosive or chemical reaction. In one method, treated proppant having a reactive coating is positioned in the formation during fracturing and reactive particles are introduced. In another method, reactive particles having a reactive core and a non-reactive coating are positioned in the fractures and react upon removal of the non-reactive coating, such as by dissolving, and reaction with a reactive particle. The waves generated by the micro-seismic events are used to map fracture space.Type: GrantFiled: June 17, 2014Date of Patent: November 22, 2016Assignee: Halliburton Energy Services, Inc.Inventors: Haluk Vefa Ersoz, Lee J.
