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 1):
A system for fracking a hydrocarbon formation at a given location along a wellbore and subsequently allowing installation of a sand screen at said location without having to \u201ctrip out\u201d a frac string prior to commencing production, comprising;\n a tubular liner insertable within said wellbore and having an interior bore, further comprising:\n (a) a plurality of spaced-apart frac ports longitudinally spaced at intervals along said tubular liner, providing, when open, fluid communication between the interior bore of the tubular liner and an exterior of the tubular liner; \n (b) a corresponding plurality of cylindrical hollow sliding sleeve members, each configured in an initial closed position to cover a corresponding set of said frac ports and prevent flow of fluid from the interior bore to an exterior of the tubular liner, and slidably moveable longitudinally in the interior bore to an open position to uncover said corresponding set of the frac ports; and \n (c) a plurality of shear members, initially securing respectively said plurality of sliding sleeve members to the tubular liner in the initial closed position thereof, and sheareable when a longitudinal force is applied thereto to thereafter allow longitudinal slidable movement of respective one of said plurality of sliding sleeve members; \n \n at least one actuation member, insertable within the interior bore of the tubular liner and engagable with at least one of the plurality of sliding sleeve members for shearing the shear members that initially secure the at least one sliding sleeve member and conditioning the at least one sliding sleeve member to the open position; \n at least one cylindrical sand screen sub, insertable within the interior bore of said tubular liner and displaceable within said tubular liner to a location therein proximate one of said frac ports in said tubular liner whose corresponding sliding sleeve member has been conditioned to the open position by said actuation member, said at least one sand screen sub 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; and \n (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, 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.
