Abstract
Corrodible wellbore plugs, systems and methods are disclosed herein. The methods include flowing a corrodible wellbore plug that is at least partially formed from a corrodible metal to a downhole location within a wellbore conduit and retaining the corrodible wellbore plug at the downhole location by operatively engaging an engagement structure with a wellbore tubular that defines the wellbore conduit. The methods include pressurizing a portion of the wellbore conduit uphole from the corrodible wellbore plug and flowing a corrosive reservoir fluid from the subterranean formation into contact with the corrodible metal to release the corrodible wellbore plug from the downhole location. The methods also may include removing the wellbore plug without utilizing a drill-out process. The systems include a corrodible wellbore plug that includes a plug body and a retention mechanism, which includes a slip ring formed from the corrodible metal and that includes the engagement structure.
