Abstract
Frangible components like shear pins, rupture disks, retainer rings, and shear rings of downhole tools (e.g., frac plugs, sliding sleeves, darts, packers, expansion joints, valves, and tool-conveyance coupling apparatuses) may be composed of a degradable material that degrades in a wellbore environment at a desired time during the performance of a subterranean formation operation. For example, a tool string may include a conveyance or top adapter sub threadably coupled to a first end of a stinger; a wellbore tool coupled to the stinger via a coupling at a second end opposing the first end of the stinger, wherein the coupling comprises a frangible, degradable shear pin and a frangible, degradable shear ring, wherein the frangible, degradable shear pin and the frangible, degradable shear ring independently comprise a degradable metal alloy selected from the group consisting of a magnesium alloy, an aluminum alloy, and any combination thereof.
