DISTRIBUTED ELECTROMOTIVE FORCE SENSING BACKGROUND

摘要

Systems and methods for formation evaluation and reservoir monitoring that use electromotive force measurements. A well monitoring system may comprise: a power supply that generates an electromagnetic field in a subterranean formation; and a distributed electromotive force sensor for measuring electromotive force at one or more points along a length of the distributed electromotive sensor, wherein the distributed electromotive force sensor comprises an optical waveguide and an electro-optical transducing layer coated on one or more lengths of the optical waveguide.
