Accomplishments, Results and Progress

Task 2: Reactive-Polymer Fracturing

  • Current cell performance limited to 120 bar and 150 ˚C

    • Current data is higher than any other in situ measurement capability

      but still short of geothermal conditions

  • Projected cell performance requirements are 300 bar, 300 ˚C
