Abstract
A fracture tool and a system includes a housing having a port, a sleeve disposed adjacent the housing and movable relative to the housing between a first position where the sleeve blocks the port and a second position where the sleeve unblocks the port, and a biaser operably connected between the housing and the sleeve. The biaser biases the sleeve to the first position. A method for fracturing a formation and producing a fluid includes opening a fracture sleeve, shifting a pressure-operated valve from an unarmed position to an armed position based upon the opening of the fracture sleeve. The method further includes applying fracture pressure to the formation, allowing the fracture sleeve to automatically close, actuating the valve with applied pressure, and flowing fluid through the valve. A borehole system including a borehole in a subsurface formation, and a fracture and production system disposed in the borehole.
