摘要：
Methods including introducing a frac plug into a wellbore in a subterranean formation, the frac plug comprising at least a mandrel, slips, and apacker element,wherein atleasta portion of the mandrel and/or the slips is composed of a degradable alloy selected from the group consisting of a magnesium alloy, an aluminum alloy, and any combination thereof. The wellbore may be a cased wellbore or an open-hole wellbore, and wherein the slips are frictionally engaged with the casing string or the wellbore wall and the packer element is compressed against the casing or the wellbore wall to set the frac plug. One or more perforations is created within the formation and the formation is hydraulically fractured. The frac plug is at least partially degraded upon contact with an electrolyte in the wellbore before or after beginning production of a hydrocarbon.
