Abstract
Our numerical proof-of-concept studies demonstrate that surface electric field measurements can provide sensitivity to both the geometric distribution of injected conductive fluids and or conductively enhanced proppant as well as sensitivity to the created hydraulic permeability of the fracture zone. This is the first demonstration of a capability to define shape and permeability of hydraulic fractures using EM systems. This work provides the necessary supporting evidence to justify new developments in joint flow and geophysical inversion for hydraulic fracture characterization. The next phase of these experiments will utilize hydro-geophysical parameter estimation capabilities of our flow and transport simulator in order to assess the resolution of the conductive fracture zone and its hydraulic permeability. Further extending this framework will involve the addition of MEQ data for the joint inversion of hydrological and EM-seismic data combinations.
