摘要： A method for a waterflooding operation in a subterranean formation includes determining a first maximum injection pressure based on an analytical model to avoid out-of-zone fracture propagation. A second maximum injection pressure is determined based on the analytical model to avoid fracture reactivation. The waterflooding operation is performed based at least on the first maximum injection pressure and the second maximum injection pressure.

摘要： A method to determine a drilling fluid density limit involves obtaining a geomechanical model of a target borehole, generating a depth of damage model of the target borehole to describe a relationship between a drilling fluid pressure and a depth of damage representing a modeled amount of yielded rock surrounding the target borehole, where the modeled amount of the yielded rock is calculated using a stress model according to a pre-determined failure criterion, and calculating, using the depth of damage model and the geomechanical model, the drilling fluid density limit as a function of the subterranean formation depth, where the drilling fluid density limit maintains the depth of damage at a target level for the target borehole, where the drilling fluid density limit corresponds to a depth gradient of the drilling fluid pressure, where the target borehole is drilled based at least on the drilling fluid density limit.
