Title: Dual sleeve stimulation tool

Abstract: A stimulation tool includes a tubular having a port; a first sleeve member disposed in the tubular and actuatable by an actuating member to move from a closed position wherein fluid communication between a bore of the tubular and the port is blocked; and a closure member disposed in the tubular and actuatable by the actuating member to a closed position wherein fluid communication through the bore of the tubular is blocked. A method of stimulating multiple zones of a tubular in a wellbore includes moving a sleeve member in the tubular by receiving an actuating member in the sleeve member; releasing the actuating member from the sleeve member; and actuating a closure member by receiving the released actuating member in a seat.
