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 17):
A method for fracking a hydrocarbon formation at a plurality of clustered contiguous locations along a wellbore within said formation and installing sand screens within a tubular liner within said wellbore at each of said plurality of locations to prevent ingress of sand into the tubular liner at each of said locations, said method comprising the steps of:\n (i) locating a tubular liner having:\n a hollow interior bore; \n a plurality of contiguous frac ports spaced along a periphery of said tubular liner; \n a corresponding plurality of sliding sleeve members respectively initially covering each of said frac ports; \n within said wellbore; (ii) situating an actuation member within said tubular liner to engage the actuation member with a first one of the plurality of sliding sleeve members, said first sliding sleeve member associated with a first set of said frac ports; (iii) actuating said actuation member to actuate the first sliding sleeve member to uncover and thereby open the associated first set of frac ports in said tubular liner and thereby allow fluid communication from said interior bore to an exterior of said tubular liner and said hydrocarbon formation via the opened first set of frac ports; (iv) continuing to actuate said actuation member to further move downhole and engage a second one of the plurality of sliding sleeve members, said second sliding sleeve member associated with a second set of said frac ports; (v) continuing to actuate said actuation member to actuate the first sliding sleeve member to uncover and thereby open the associated second set of frac ports in said tubular liner and thereby allow fluid communication from said interior bore to an exterior of said tubular liner and said hydrocarbon formation via the opened second set of frac ports; (vi) injecting a fracking fluid into said tubular liner and causing said frac fluid to flow into the hydrocarbon formation via the opened first and second sets of frac ports; (vii) situating a first sand screen sub within said tubular liner, said first sand screen sub having a resiliently-outwardly biased protuberance having a profile, and said first sand screen sub further having an annular screen mesh about an outer periphery thereof, (viii) applying a pressurized fluid to an uphole end of said first sand screen sub and causing said first sand screen sub to flow downhole to a position in said tubular liner where said annular screen mesh thereof underlies said second set of open frac ports and causing said profile of said protuberance thereon to engage a mating profile on an interior of said tubular liner and thereby retain said first sand screen sub and said annular screen mesh thereof underlying said second set of open frac ports; (ix) situating a second sand screen sub within said tubular liner, said second sand screen sub having a resiliently-outwardly biased protuberance having a profile different than the profile of the protuberance on said first sand screen sub, and likewise having an annular screen mesh about an outer periphery thereof; (x) applying a pressurized fluid to an uphole end of said second sand screen sub and causing said second sand screen sub to flow downhole to a position in said tubular liner where said annular screen mesh thereof underlies said first set of open frac ports, and causing said profile of said protuberance thereon to engage a mating profile on an interior of said tubular liner and thereby retain said second sand screen sub and said annular screen mesh thereof underlying said first set of open frac ports.
