The $255,963 National Science Foundation grant to Teverra LLC will support the development of an innovative downhole tool for direct measurement of in-situ rock stresses in deep well environments. Funded through the NSF Engineering Directorate's $47.041 million CFDA program, the Phase I project aims to design, model, and prepare prototypes for a modular stress measurement tool applicable to vertical, deviated, and horizontal wells. Key objectives include analytical and numerical solutions to determine far-field stresses from near-wellbore measurements, tool component design for borehole sizes from 7-12 inches, and modeling of different downhole conditions. If successful, the automatic, sensor-based tool could improve safety and economics for subsurface operations like carbon sequestration, geothermal energy, and fossil fuel extraction by providing direct stress measurements to optimize well design and management.
