Dissolvable setting tool or hydraulic fracturing operations

A method for hydraulic fracturing or stimulation operations in a wellbore, the method comprising:

• deploying a frac package into a wellbore string in the wellbore;
• detecting a predetermined depth in the wellbore string with a controller of a setting tool carried by the frac package;
• providing a trigger signal to an actuator of the setting tool in response to detecting the predetermined depth;
• increasing a pressure in a hydraulic chamber of the setting tool in response to receiving the trigger signal,
• moving a piston of the setting tool in response to increasing the pressure;
• moving a seal element of a frac plug carried by the frac package with the actuator in response to moving the piston, wherein moving the seal element engaging the seal element with the wellbore string to fluidly isolate a perforation zone in the wellbore;
• pumping a fluid into the perforation zone isolated by the frac plug to hydraulically fracture or stimulate the wellbore;
• and
• degrading the setting tool, including the hydraulic chamber and the piston, into individual particles less than one half inch diameter in wellbore fluids in the wellbore.

A frac package apparatus useful in hydraulic fracturing or stimulation operations, the apparatus comprising:

• a perforating gun;
• a frac plug including a seal element movable from a first radially inward position to a second radially outward position;
• a dissolvable setting tool operably coupled to the perforating gun and the frac plug, the setting tool including an actuator operably coupled to the frac plug to selectively move the seal element from the first position to the second position in response to receiving a trigger signal, wherein the actuator of the setting tool includes a hydraulic chamber and a piston movable in response to a change in pressure in the hydraulic chamber to move the frac plug from the first radially inward position to the second radially outward position, and wherein the dissolvable setting tool, including the piston and the hydraulic chamber, is constructed of dissolvable materials such that the dissolvable setting tool degrades into individual particles less than one half inch diameter in wellbore fluids;
• and
• a controller carried by the dissolvable setting tool, the controller operable to provide the trigger signal to the actuator in response to detecting a predetermined depth in a wellbore.
