Abstract:Measuring fracture closure pressures serves as calibration points to constrain the geomechanics model necessary for conducting cap rock integrity and seal assessment analysis for subsurface injection projects. Formation breakdown, permeability, and in-situ stress contrast are required to constrain the CO2 injection rate. Frequently, the measured formation breakdown pressure is higher than the elastic breakdown pressure predicted through geomechanical characterization. Additionally, operational constraints and … Show more
