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 16):
The method as claimed in  claim 10  for further conducting a fracking procedure at a plurality of spaced apart locations along said wellbore and installing sand screens within the tubular liner at each of said plurality of locations to prevent ingress of sand into the tubular liner at each of said locations, wherein after step (vi) such method further comprises carrying out the following further steps:\n (vii) situating a second actuation member within said tubular liner to engage the first actuation member with a second one of the plurality of sliding sleeve members, said sliding sleeve member associated with a second set of said frac ports; \n (viii) actuating said second actuation member to actuate the 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 associated frac port; \n (ix) injecting a fracking fluid into said tubular liner and causing said frac fluid to flow into the hydrocarbon formation via the opened second set of frac ports; \n (x) situating a second sand screen sub within said tubular liner, said second sand screen sub having a resiliently-outwardly biased protuberance thereon and an annular screen mesh about an outer periphery thereof; and \n (xi) 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 screen mesh thereon underlies said second set of frac ports, and causing said resiliently-outwardly biased protuberance on said second sand screen sub to engage a mating profile on an interior of said tubular liner proximate said second set of frac ports so as to thereby retain said second sand screen sub and said annular screen mesh thereof underlying said second set of frac ports.
