Abstract
Systems and methods for pressure-cycled stimulation during gravity drainage operations. These systems and methods include increasing a pressure within a stimulation well that extends within a subterranean formation and subsequently decreasing the pressure within the stimulation well to increase production of viscous hydrocarbons from a production well. The systems and methods include repeating the increasing and the decreasing for a plurality of stimulation cycles and producing viscous hydrocarbons from the subterranean formation during the increasing, the decreasing, and the repeating. The increasing may include increasing a reservoir pressure within the subterranean formation to a pressure that is greater than a bubble point pressure of the viscous hydrocarbons, and the decreasing may include decreasing the reservoir pressure to a pressure that is less than the bubble point pressure of the viscous hydrocarbons.
