… In such case, CO 2 leakage occurs along reactivated faults. … , fresh water leaks downward
difficultly and more brine leaks … brine leakage rate reduces quickly, while fresh water leakage …

… In our shale fault experiments, we observe “similar” mechanisms of transient permeability
increase related to complex fault rupture, such as a strong decrease of normal stress, slip and …

… mechanisms that may lead to the generation of leakage … Water saturated CO 2 is slightly
denser than water, promotes … reactions, develops fractures, or reactivate faults. However, the …

… In addition, water leakage between the fault plane and the blocks is allowed. Flow in the
blocks follows the Darcy law. The fault plane is divided into 0.2 to 0.6 m mesh elements that …

… fault slip and permeability by analyzing a water injection test performed in a fault zone …
the amount of leakage from the injection chamber into the reactivate fault (Simulation 2) and …

… obligatory to understand the mechanism of the phenomenon of leakage of water due to
infiltration… Following this appearance, we can think of the reactivation of the area of the old vortex …

… mechanisms of fault reactivation is based on the Mohr–Coulomb criterion, which incorporates
the effective stress principle, stating that whether a fault is reactivated … water leakage. (2) …

… to water injection may cause fault cutting through a reservoir to be reactivated, causing oil
leakage to … Under this assumption, a critical reservoir pressure without reactivating a fault was …

… mechanisms of fault opening and slip favor permeability increase, therefore enhancing fluid
leakage … of fault movement during pressurization by water in the borehole interval the fault …

… much pump rate we should choose for reactivating the natural fractures remain poorly
understood… Theories and experiments both proved that natural fractures could be reactivated …
