Tenth Year Annual Report:
Carbon Storage: Storage Results - 2010
- Cement durability experiments have been completed and provide the necessary input data for
- Based on measured corrosion rates, it is predicted that acidified brine would be rapidly
neutralized as it flows upward through a crack or annulus in well cement, so small leaks
would not grow into large ones as a result of corrosion.
- An apparatus for carrying out indentation measurements has been constructed and permits
profiling of the mechanical damage in corroded cement.
- The advanced poromechanical capabilities of dynaflow have been used to simulate injection
at In Salah.
- Analytical and semi-analytical models have been expanded to make them more broadly
applicable, yielding even faster field-scale simulations with fewer assumption.s
- Simulations of CO2 injection fields with brine management show that injection pressures can
be substantially reduced, allowing for greater injection rates that can be optimized over time.
- Molecular modeling has revealed a strong dependence of gas hydrate stability on the 3-D
structure and occupancy of the "cages" that contain CO2 molecules.
