Proppant dust suppression compositions including: (a) at least one sugar alcohol ester and (b) at least one sugar alcohol esters and methods for using the compositions, wherein the composition is adapted to reduce dust in a dust-containing material by about 30% and about 100% and wherein the at least one sugar alcohol ester improves flowability of treated dust-containing material.

Deployable smart acoustic resonance particles have dense cores, compliant matrixes surrounding the cores and stiff outer shells surrounding the matrixes. The particles have mechanical stress sensitivities that provide unique band gap shifts when compressed. Groups of similar particles with similar stress sensitivities and similar band gap shifts are added at different times to hydraulic fluids, as circulated through wells with the fluid and pushed into fractures. A plural, sonic monopole well logging tool is lowered into the well to determine locations and depth of fractures and local pressures by distinct resonance of individual groups.

An in-line treatment cartridge and methods of using same are disclosed. The in-line treatment cartridge can include a cylindrical body configured to allow fluid to flow therethrough and a plurality of particulates contained within the body. At least one particulate of the plurality of particulates can include a chemical treatment agent. The at least one chemical treatment agent can separate from the at least one particulate upon contact with a fluid.

The present disclosure describes electro-hydrofracturing (E-HF) using electrically conductive proppants and methods for hydraulic fracturing using electrically conductive proppants.

The present invention provides environmentally-friendly compositions and methods for degrading polymers used in fracking operations to enhance the recovery of oil and gas. Specifically, the compositions and methods utilized microorganisms and/or their growth by-products to degrade polymers, such as PGA, PLA and PAM, used in fracking wells.

Loose particulate materials can be problematic in various aspects. For example, loose particulate materials may generate dust or be difficult to consolidate together. Fines in loose particulate materials may also be an issue. Coated particulates may alleviate some of the foregoing issues. Suitable coated particulates may comprise a particulate material comprising sand or a ceramic, and a polysaccharide composition coated upon the particulate material, the polysaccharide composition comprising a functionalized polysaccharide. Other particulate materials such as wood chips and animal litter particulates may be coated with functionalized polysaccharides to achieve similar advantages.

Producing proppants with nanoparticle proppant coating include coating the proppant particles with a strengthening agent, functionalized nanoparticles, and unfunctionalized organic resin to produce proppant with nanoparticle proppant coating. Additionally, a proppant comprising a proppant particle and a nanoparticle proppant coating is provided. The nanoparticle proppant coating includes a strengthening agent, functionalized nanoparticles, and unfunctionalized organic resin. The nanoparticle proppant coating coats the proppant particle.

Methods for completing hydrocarbon wells using variable rate fracturing are provided herein. One method includes positioning a perforation device within a tubular conduit of a downhole tubular, where the downhole tubular extends within a wellbore, and where the wellbore extends within a subsurface region, as well as perforating the downhole tubular using the perforation device to define perforations within the downhole tubular. The method also includes pumping a slurry including fracturing fluid and a lightweight proppant into the tubular conduit according to a variable pumping rate schedule to fracture zones of the subsurface region that are proximate to the perforations, forming corresponding fractures within the subsurface region. The method further includes flowing the slurry into the fractures, via the perforations, to prop the fractures with the lightweight proppant, where the lightweight proppant includes granules formed from a polyolefin, petroleum coke, and/or a polyaromatic hydrocarbon resin.
