An actuation member for use in fracking operations, which immediately prior to fracking locates a sand screen at a desired location along a tubing liner and eliminates having to trip out the frac string prior to commencing production. The actuation member comprises a cylindrical hollow collet sleeve, with one or more radially-outwardly biased protuberances forming a unique profile which further matingly engages a corresponding mating profile on one of a plurality of sliding sleeve members in the tubular liner. A longitudinally-extending sand screen is provided, longitudinally slidable on the actuation member. A spring member, adapted to be forcibly compressed by the sand screen member when pressurized fluid is applied, and decompressed upon removal of pressurized fluid, is further provided on the actuation member.

A method of forming a ceramic-coated proppant, including receiving a proppant or particle and coating the proppant or particle with ceramic to give a ceramic coating on the proppant or particle. A method of hydraulic fracturing a geological formation with the ceramic-coated proppant.

The disclosed hydraulic fracturing fluid can include a liquid solvent, one or more surfactants, a proppant-forming compound, and one or more curing agents. When injected into a wellbore, the hydraulic fracturing fluid reacts to form proppant pillars in-situ under downhole conditions. The proppant pillars are capable of maintaining conductive fractures.

A hydraulic fracking aqueous fluid, including: water; one or more soluble calcium salts; a carbonate ion generating compound; and one or more soluble zinc salts. A method for fracking an underground formation using the hydraulic fracking fluid.

A sand separation system and method for operating a sand separation system, in which the method includes separating sand from a fluid using a separator. The method includes, signaling for a blowdown unit to blowdown the separator, opening one or more blowdown valves of the blowdown unit coupled to the separator in response to the signaling, so as to blowdown the separator, and receiving the sand from the separator into a sand disposal unit. The sand passes through the one or more blowdown valves that are opened. The method includes measuring a weight of at least some of the sand that was separated in the separator using a load cell of the separator, a load cell of the sand disposal unit, or both, and determining a blowdown interval for subsequent blowdown operations of the separator based in part on the weight of the sand.
