Abstract: Implementations described and claimed herein provide systems and methods for breaking cement within an annulus of a wellbore. In one implementation, an annulus cement breaking system includes a cement compression tool operable to be disposed within an inner bore of a casing having a longitudinal length. The casing is disposed within a wellbore formed in a subterranean formation having a cement layer disposed within an annulus formed between the casing and the subterranean formation. One or more actuation elements are coupled with the cement compression tool, and the one or more actuation elements are operable to engage the inner bore. The one or more actuation elements are transitionable between an unactuated state and an actuated stated. The actuated state operable to engage the inner bore of the casing, thereby radially expanding the casing and compressing the cement layer.
