Interventionless pressure operated sliding sleeve
A zone to be treated comprises a plurality of sliding sleeve valves. The sleeve defined opposed chambers charged with pressurized fluid on opposed sides of the sleeve. Valves responsive to a remote signal with no borehole intervention change the pressure balance on the sleeve to get it to open from a closed position and then close and then to reopen for production. One way this is done is by sequential pressure bleeding off from the opposed chambers. A zone having multiple such valves can be treated without need for dropping balls and subsequent milling out, which allows production to commence sooner with reduced restrictions to flow from the ball seats and without the debris associated from a milling operation. |
