Abstract:
A system and method for successively fracking a wellbore at spaced intervals along tubing having therein frac ports each openably closed by a sliding sleeve. The system has at least one actuation member and at least one cylindrical sand screen sub insertable into the tubing. Each actuation member has a collet sleeve with a radially-outwardly biased protuberance of a first profile configured to matingly engage an interior groove profile on at least one of the sliding sleeves and slide the sliding sleeve downhole to open the corresponding port. Each cylindrical sand screen sub has a dissolvable plug member or burst plate disposed on one end thereof allowing for the sand screen to be forced into the well by pressure acting against the plug or plate, and has a resiliently-outwardly biased protuberance configured for engaging a mating profile on the tubing and retaining the sand screen sub in a desired position.

Claim (Index 26):
The sand screen sub as claimed in  claim 25 , wherein said resiliently outwardly biased retaining member on said at least one sand screen sub has a chamfer on a downhole side edge thereof and a flat face on an uphole side edge thereof perpendicularly disposed to a longitudinal axis of said tubular liner; and\n wherein downhole movement of said at least one sand screen sub in said tubular liner is allowed by said chamfer causing said resiliently outwardly biased retaining member to become radially depressed upon fluid pressure being exerted on an uphole side of said sand screen sub; and wherein uphole movement in said sand screen sub is prevented, when said screen mesh of said sand screen sub underlies said one or more opened frac ports, by said flat face engaging, directly or indirectly, an annular region in said tubular liner.
