Single-phase annulus-operated sliding sleeve

A sliding sleeve is provided to control the flow of fluids through a tubular conduit. The sliding sleeve may include a housing having a longitudinal bore, at least one annulus pressure port, and at least one fluid flow port. An inner sleeve is disposed for axial movement within the longitudinal bore of the housing, and includes at least one fluid flow port for sealably cooperating with the fluid flow port in the housing to control the flow of fluids through the tubing string. A piston is associated with the inner sleeve and the housing. The piston is initially releasably secured to the housing. The sliding sleeve is initially provided with the fluid flow ports in a closed position, and is actuated by applying annulus pressure to the piston through the at least one annulus pressure port in the housing. The annulus pressure releases the piston from the housing and forces the piston and inner sleeve upwardly to establish fluid communication through the fluid flow ports.
