Title: Modular electrode tool for improved hydraulic fracture diagnostics

Abstract

Systems and methods for assessing physical properties of a geological formation are disclosed. The systems and methods may use electrodes that include two conductive portions separated by an isolation gap positioned along a casing in a wellbore in the formation. The electrodes may be sequentially energized to provide excitation stimulus into the formation while the remaining, non-energized electrodes may substantially simultaneously receive excitation responses to the excitation stimulus from the formation. The excitation responses may be assessed to determine one or more physical properties of fractures in the formation.
