Abstract:
A system ( 1 ) for stimulating a well with an annulus ( 3 ) formed by a string ( 2 ) and a wellbore ( 4 ), wherein the system ( 1 ) comprises a pressure activated injection assembly ( 200 ) configured to open at an activation pressure below an injection pressure and a mechanically operated sand control assembly ( 100 ) configured to flush the annulus ( 3 ) after injection. The system ( 1 ) comprises a pressure activated flushing device ( 500 ) mounted uphole from the injection assembly ( 200 ) and configured to open radial flush ports ( 501, 502 ) between the interior of string ( 2 ) and the annulus ( 3 ) at a flushing pressure above the injection pressure. An optional release mechanism for the pressure activated injection assembly ( 200 ) is also disclosed.

Claim (Index 8):
The system according to  claim 7 , wherein the release mechanism comprises an inner sleeve with an inner piston area exposed to a central bore, a radial release opening and an outer piston area;\n a return spring opposing a pressure force exerted on the inner piston area;\n a release sleeve arranged between a fixed housing and the inner sleeve; wherein \n the inner sleeve is axially movable between an idle position and a release position in which the radial release opening opens an inner fluid connection from the central bore to the outer piston area;\n the release sleeve is axially movable between \n a normal operations position in which the release sleeve closes the inner fluid connection and opens an outer fluid connection from the exterior of the housing to the outer piston area and an inactivation position in which the release sleeve ( 620 ) closes the outer fluid connection\n and opens the inner fluid connection; and \n wherein the release mechanism is configured such that the inner sleeve reaches the release position when the intermediate pressure is exerted on the inner piston area, and such that the release sleeve shifts from the normal operations position to the inactivation position when the inner sleeve shifts from\n the release position to the idle position.
