Abstract
A dissipation equilibrium value for a well operation may be determined based on a height of a fracture within a layer and a limit on the change of the height of the fracture (fracture height change limit). A pressure limit for the well operation may be determined based on the dissipation equilibrium value, stress in the layer, and stress in a bounding layer. The pressure limit may be used to control the pressure of the well during the well operation, and prevent growth of the fracture beyond the fracture height change limit.
