Utah FORGE 5-2419: Temperature Testing of Proppants for EGS and Stimulation of Electromagnetic Fracture Mapping Using Electrically-Conducive Proppants - 2024 Annual Workshop Presentation

This is a presentation on the Temperature Testing of Proppants for EGS and Stimulation of Electromagnetic Fracture Mapping Using Electrically-Conducive Proppants by Stevens Institute of Technology, presented by Cheng Chen. This video slide presentation discusses well controlled laboratory experiments testing the high-temperature performance of electrically-conductive and non-electrically-conductive proppants in maintaining fractures hydraulic and electrical conductivities to understand and quantify the thermal-hydrologic-mechanical-chemical mechanisms that regulate the observed behaviors. This will be tested using proppant/fracture imaging via borehole electromagnetic measurements. This presentation was featured in the Utah FORGE R&D Annual Workshop on August 15, 2024.

Modular electrode tool for improved hydraulic fracture diagnostics

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.
