Feasibility of streaming potential measurements during hydrofracturing
A simple model study shows that the onset of hydraulic fracturing and eventually fracture directions may be detected in streaming potential measurements. To model streaming potential responses of hydraulic fracturing, a theory of slowly time-varying electrokinetic phenomena and a self-consistent model to describe rock conductivities in terms of intrinsic rock properties are developed. Measureable streaming potential responses are generated during the hydraulic fracturing process. The fracturing process amplifies the observable streaming potential response by up to one order of magnitude when compared to a similar experiment without fracturing. The resolution of fractures is better in monitoring wells than on the surface.
