Ahmadian and Team Advance Subsurface Sensing Technology with Electrically Active Proppant Research
March 7, 2022
Mohsen Ahmadian is a Bureau researcher and the program manager of the Advanced Energy Consortium (AEC). He leads a research project to demonstrate a new approach to real-time monitoring of dynamic changes in pressure, salinity, and flow in hydraulically fractured (HF) networks. The project has achieved early successes, and achieving its objectives would provide technology to improve production from oil and gas reservoirs, particularly unconventional “tight” reservoirs, previously fractured reservoirs, and currently uneconomic conventional reservoirs. Results from this project will also be useful in hydrogeology, subsurface environmental monitoring, carbon sequestration, and geothermal energy production. Additionally, the unique field data sets collected in this study will lay the foundation for the advancement of geophysical mapping and modeling techniques in general.
Bureau of Economic Geology Awarded $3.7 Million by the U.S. Department of Energy

Bureau Awarded $1.5 Million to Further Research into Remote Monitoring of Hydraulically Fractured Networks
October 4, 2019
The Bureau of Economic Geology has just been awarded a $1.5 million grant by the U.S. Department of Energy (DOE) to build on previous research by its Advanced Energy Consortium (AEC) into real-time remote monitoring of hydraulically fractured networks. The goal of the funded project is to create a more efficient and accurate process to characterize the subsurface in real time following hydraulic-fracturing operations.
Hydraulic fracturing has evolved into a sophisticated multistep process that differs from well to well. Operations use varying flow rates, fluids, and proppant amounts and sizes. Current tools, such as microseismic and tiltmeter monitoring, can provide information on fracture extent but provide little or no information on the movement and final distribution of proppants or production fluids.
