This paper describes conceptual models for an inverse analysis to investigate fracture topology at Reykjanes geothermal reservoir using electrical resistivity. The resistivity distribution of a field can be estimated by measuring potential differences between various points while injecting an electric current into the ground, and resistivity data can be used to infer fracture properties due to the large contrast in resistivity between water and rock. Furthermore, injecting water into the reservoir with higher resistivity than the conductive brine at Reykjanes would cause a time-dependent change in the resistivity of the fractures as the fluid flows through the fracture network. Thus, modeling the time history of the potential difference between two points (e.g. an injector and a producer) as water is injected into the reservoir and comparing simulated results to actual observation that depend on the fracture network in the field, could help estimate where fractures are located and the characterize their distribution.
