Mechanistic insights into the early hydration kinetics of oil-well cement controlled by calcined shale-gas drill cuttings: a multi-scale characterization and kinetic-model approach

This study investigates how calcined shale-gas drill cuttings (CDC) regulate early oil-well cement hydration. CDC is pozzolanic, yet its dissolution releases Al3+ ions that adsorb onto C3S surfaces, inhibiting dissolution and prolonging induction by 23.5%, 41.2%, and 111.8% for 30%, 50%, and 70% CDC...
