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 5):
A system for fracking a hydrocarbon formation as claimed in  claim 2 , further comprising:\n a second sand screen sub, insertable within the interior bore of said tubular liner comprising:\n (a) a cylindrical hollow member having at an uphole end thereof a dissolvable plug member or burst plate which at least for a limited time substantially obstructs passage of fluid within said interior bore thereby causing pressurized fluid injected downhole in said bore of said tubular liner to force said sand screen sub downhole in said tubular liner; \n (b) a cylindrical, longitudinally-extending oil-permeable screen mesh forming a portion of an outer periphery of said second sand screen sub downhole from said dissolvable plug member or burst plate thereon, which screen mesh when said sand screen sub is located proximate said one of said frac ports, underlies said one of said frac ports and prevents ingress of sand but permits ingress of oil, from said formation into the interior bore via said one of said frac ports; and \n (c) a retaining member on said cylindrical hollow member, which engages, directly or indirectly, said tubular liner when said second sand screen sub has flowed down said tubular liner to another of said frac ports whose corresponding sliding sleeve member has been opened on said tubular liner by a second actuation member to a position wherein the screen mesh of said sand screen sub underlies said another of said frac ports, which retaining member after engagement with said tubular liner prevents uphole displacement of said second sand screen sub in said tubular liner.
