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 24):
A sand screen sub insertable within an interior bore of a tubular liner and displaceable within said tubular liner to a location therein proximate one or more opened frac ports in said tubular liner, said sand screen sub comprising:\n (a) a cylindrical hollow member having at an uphole end thereof a dissolvable plug member or burst plate, said dissolvable plug member or burst plate being configured for, when said sand screen sub is inserted within the interior bore, at least for a limited time substantially obstructing 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; and (b) a cylindrical, longitudinally-extending oil-permeable screen mesh forming a portion of an outer periphery of said sand screen sub downhole from said dissolvable plug member or burst plate thereon, wherein said screen mesh is configured for, when said sand screen sub is located proximate said one or more opened frac ports, underlying said one or more opened frac ports, and preventing ingress of sand but permitting ingress of oil, from said formation into the interior bore via said one or more opened frac ports.
