Abstract: An actuation configuration including a baffle having an opening, a plug comprising a plug material extrudable into the opening and compactable therein to hold a differential across the baffle. A borehole system including a housing, a seat in the housing presenting an opening, a plug comprising a plug material extrudable into the opening and compactable therein to hold a differential across seat. A method for treating a borehole including running a plug onto a baffle, extruding plug material into an opening of the baffle, compacting the plug material in the opening to support a target differential pressure across the baffle, and actuating a borehole tool. A method for treating a borehole including running a deformable plug through a restriction, landing the plug on a seat having an opening, compacting material of the deformable plug into the opening to support a differential pressure thereacross, actuating a borehole tool.
