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 23):
A method for successively uncovering spaced-apart frac ports situated along a hollow tubular liner, carrying out a fracking operation at each uncovered frac port, and installing a sand screen at each of said uncovered frac ports, comprising the steps of:\n (i) locating an actuation member in said tubular liner, said tubular liner initially having a plurality of sliding sleeve members respectively covering a corresponding plurality of said spaced-apart frac ports along said tubular liner; (ii) flowing said actuation member downhole to engage one of the plurality of sliding sleeve members covering an lowermost covered frac port along said tubular liner, and actuate said actuation member and said lowermost sliding sleeve member to together move downhole and thereby uncover an associated of said ports in said tubular liner; (iii) injecting a pressurized frac fluid into said tubular liner to frac the formation at the location of the opened frac port; (iv) injecting a sand screen sub down said tubular liner, said sand screen sub having a resiliently-outwardly biased protruding member thereon, wherein upon the sand screen sub reaching said first actuation member, the resiliently-outwardly biased protruding member then engages a mating profile on an interior of said tubular liner and thereby retains the sand screen sub in a position underlying said opened port and said protruding member thereafter prevents said sand screen sub from moving back uphole; and (v) repeating steps (i)-(vi) until all of said plurality of spaced-apart ports along said tubular liner have been uncovered, the wellbore fracked at each opened frac port, and sand screen subs installed at each opened frac port.
