Patent number: 10101495Abstract: Systems and methods are provided for a magneto-seismic exploration of a subsurface region. An electromagnetic source may transmit time-varying electromagnetic field into the subsurface region, in the presence of a static or time-varying magnetic field, such that a component of the electric field associated with the time-varying electromagnetic field is substantially parallel to an interface between two subsurface formations in the subsurface region, wherein the electric field interacts with the static or time-varying magnetic field and creates a Lorentz force in each of the subsurface formations. One or more seismic receivers may detect a seismic signal generated by a Lorentz force change at the interface between the two subsurface formations. A computer system may be programmed to process and present the detected seismic signal.Type: GrantFiled: February 28, 2017Date of Patent: October 16, 2018Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Qiuzi Li, Harry W.
