Subsurface sources constitute the Nation’s primary source of energy providing more than 80 percent of total U.S. energy needs today), and they are also critical to the Nation’s secure energy future. Next generation advances in subsurface technologies will enable access to more than 100 gigawatt-electric GWe) of clean, renewable geothermal energy, as well as safer development of domestic natural gas supplies. Of particular interest is the development of advanced wellbore elastomers, specifically to improving the functionality, reliability, and durability of elastomeric materials designed for use in harsh downhole environments specific to geothermal energy development in conditions with elevated temperatures of greater than 225°C for long-term applications months to years) and 300°C for shorter duration applications days to weeks). Triton Systems will fabricate various elastomeric nanocomposite formulations that are expected to have thermal, chemical, abrasion resistant properties suitable for the harsh geothermal environment. The fabrication of the nanocomposite formulations, as well as the mechanical and chemical characterizations will be done at Triton Systems – simulated geothermal testing conditions will be performed. In a Phase I effort, Triton Systems will fabricate a series of elastomeric nanocomposite materials. Characterization of the elastomer’s mechanical properties, as well as its resistance to high temperatures and geothermal brines will be evaluated. The data collected will be used in models to optimize material composition for geothermal applications. Improvements in elastomeric materials will enable advancements in wellbore integrity, permeability manipulation, and interpretation of new subsurface signals. The success of this program will lead to cheaper, safer, and more efficient high temperature elastomers for both geothermal and oil & gas applications.
