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.

Fluid characteristics of a well fluid can be monitored. For example, a computing device can receive sensor signals from an acoustic sensor positioned on a well tool. The sensor signals can indicate characteristics of acoustic emissions generated by a well fluid impacting the well tool. The computing device can determine an acoustic signature for the well fluid using the characteristics of the acoustic emissions. The computing device can determine a difference between the acoustic signature a baseline acoustic-signature for the well fluid. The computing device can determine one or more fluid characteristics of the well fluid using the difference between the acoustic signature and the baseline acoustic-signature. The computing device can transmit a notification indicating the one or more fluid characteristics.

Techniques of the present disclosure relate to proppant flowback control using a plug and perf completion. A method comprises disposing a resin in at least one cluster of fractures of a stage; disposing an activator for the resin in the stage; displacing the activator from the wellbore and into the at least one cluster of the stage with a plug attached to a perforating apparatus; setting the plug such that the resin and the activator are contained in the stage; and perforating a subsequent stage.

Methods for treating a formation may include introducing components of a treatment solution into a wellbore such that the treatment solution contacts the formation to be treated, where the treatment solution may include urea, urease, a calcium ion source, one or more polysaccharides, a casein protein, a protease, an ionic compound, and a sugar, where the formation may have an amount of sand production before treatment and may be in fluid contact with the wellbore, and where an amount of sand production after treatment may be less than the amount of sand production before treatment. Consolidated sand structure compositions may include previously unconsolidated sand interlinked by inter-particle cementitious bonds comprising deposited calcium carbonate crystals, where the consolidated sand has a structural strength and the consolidated sand structure is porous to permit fluid flow through the composition.

Sand consolidation for a subterranean formation can be achieved by adding a curable resin to a drilling fluid. The curable resin can be a furan- or epoxy- or silane-based resin. The drilling fluid can form a filtercake on a wellbore wall. A filtercake-removal fluid can provide a dual function to remove the filtercake and cure the curable resin, which consolidates formation particles. A curing agent can also be included in the filtercake-removal fluid. Sand consolidation can also be achieved by adding the curable resin to the filtercake-removal fluid. The resin can penetrate into the formation as the filtercake is being removed and then cure.

A method of treating a subterranean formation including providing a treatment fluid comprising a hardenable acid curable resin and a hydrolysable dimer acid ester. The treatment fluid is combined with a carrier fluid and is introduced into a subterranean formation. Upon the hydrolyzing of the ester in the formation and the contacting of unconsolidated proppants, the treatment method produces consolidated proppants.

One or more embodiments relates to a productive consolidated sand pack product. The sand pack product may be a cured resin that is bound to sand particles and has a porous structure. The sand pack product is obtained from curing a resin composition which may include a resin, a curing agent, a chemical blowing agent, a surfactant, a carrier fluid, a pH agent, and a salt. The porous volume may include one or more of trapped gas, bubbles, and open or connected pore space.

Resin coatings are frequently formed in conjunction with performing a subterranean treatment operation. However, poor thermal conductivity and mechanical strength of resin coatings can be problematic in a downhole environment and eventually lead to their breakdown. Methods for enhancing a resin coating in a downhole environment can comprise: introducing a treatment fluid comprising a curable resin and a carbon nanomaterial into a wellbore penetrating a subterranean formation; forming a coating of the curable resin on a surface in the wellbore, the carbon nanomaterial being dispersed throughout the coating; and curing the curable resin to form a cured resin coating.

Migration of formation solids in a wellbore is restrained by feeding a slurry, comprising water, a viscosifier, and a concentration of cement clinker particles, into the wellbore, and hydrating the clinker particles in the wellbore. The clinker particles are kept in suspension during the hydrating, and upon completion of the hydrating the hydrated clinker particles form a hardened cement consisting of a permeable structure of interconnected hydrated clinker particles. A layer of degradable lost circulation material (LCM) may be employed to separate the slurry with clinker particles from the formation surrounding the wellbore during hydrating of the clinker particles.
