1. A cylindrical actuation member for use in fracking operations, insertable within a tubular liner when fracking a hydrocarbon formation at a given location along said tubular liner, which immediately locates a sand screen member at said location after fracking without having to trip out a frac string prior to commencing production, comprising:
(i) an elongate cylindrical hollow collet sleeve, having a radially-outwardly biased protuberance on a periphery thereof having a unique profile, said radially-outwardly biased protuberance configured to matingly engage an interior circumferential groove on a corresponding one of a plurality of sliding sleeve members within said tubular liner;
(ii) a dissolvable or burstable plug member, situated in said cylindrical hollow collet sleeve at an uphole end thereof which at least for a limited time, prevents pressurized fluid from travelling through said cylindrical hollow collet sleeve;
(iii) a longitudinally-extending sand screen member, longitudinally slidably moveable along said cylindrical hollow collet sleeve, adapted to prevent passage of sand therethrough but permit passage of bitumen or oil therethrough; and
(iv) a spring member, situated adjacent and downhole to said sand screen member, adapted to be forcibly compressed by said sand screen member when pressurized fluid is applied to an uphole end of said cylindrical hollow collet sleeve and to be decompressed upon removal of pressurized fluid against said cylindrical hollow collet sleeve and thereafter longitudinally reposition said screen member in an uphole direction.
