Method of carbon sequestration by capturing CO.sub.2 emissions and making a proppant from the captured carbon in either a carbon mineralization process or in a carbon nanomaterial manufacturing process, followed by treatments to ensure the quality control of the proppants so that they are suitable for use in hydraulic and other reservoir fracturing methods. Injection of the manufactured proppant in fracking thus sequesters the carbon from the original captured CO.sub.2 in the reservoir.

A method includes introducing into a drilling fluid a plurality of tags having a first clay nanoparticle and a first polymer embedded into the clay nanoparticle and circulating the drilling fluid and tags through a well during a drilling operation that creates formation cuttings such that the tags interact with the formation cuttings, creating tagged cuttings. The returned cuttings are collected from the circulating drilling fluid at a surface of the well, and the tags on the returned cuttings are detected to identify the tagged cuttings. The method also includes correlating the tagged cuttings with a drill depth in the well from the drilling operation.

A method of pretreating a pipeline or apparatus is carried out by selecting a colloidal particle dispersion having inorganic nanoparticles with an average particle size of from 500 nm or less that exhibit properties of Brownian motion. Surfaces of a pipeline or apparatus are contacted with a treatment composition comprising the colloidal particle dispersion. The colloidal particles of the treatment composition are allowed to adhere the surfaces of the pipeline or apparatus to facilitate a reduction in friction of the surfaces of the pipeline or apparatus and/or lower the pressure drop of fluid flowing over the surfaces of the pipeline or apparatus and/or to reduce the formation of surface deposits on the surfaces of the pipeline or apparatus.

This present invention relates to compositions and methods of enhancing the dispersion of nanoparticles. In certain embodiments, the compositions and methods can be used for enhancing the performance and/or longevity of primers using biochemical-producing microbes and/or byproducts synthesized by the microbes. In certain embodiments, the addition of biosurfactants can enhance the dispersion of pigments and/or other nanoparticles, as well as inhibition of stain or color bleeding through the primer.

A multicomponent nanocapsule composition comprising a core particle, an oil phase encapsulating the core particle, and an aqueous phase in which the encapsulated core particle is suspended is provided. The porous particle includes a cationic surfactant encapsulated in a porous particle. The oil phase includes an anionic surfactant and a zwitterionic surfactant. A method of making a multicomponent nanocapsule composition is also provided. A method of treating a hydrocarbon-bearing formation with the multicomponent nanocapsule composition is provided. The method may include providing a multicomponent nanocapsule composition, introducing the multicomponent nanocapsule composition into the hydrocarbon-bearing formation, displacing hydrocarbons from the hydrocarbon-bearing formation by contacting the multicomponent nanocapsule composition with the hydrocarbons, and recovering the hydrocarbons.

A modified high density brine for use in subterranean drilling and completion operations. The modified high density brine includes the addition of high density particle addition that can optionally be surface-modified. The resultant modified high density brine eliminates the need for toxic, corrosive, and costly ZrBr.sub.2 additions or other ionic additives to boost the density of the modified high density brine to 15-17 lbs./gallon or greater.

A preparation method of a fully adaptive modified nanographene plugging type anti-collapse drilling fluid is disclosed. A modified nanographene slurry anti-collapse agent and a water-based drilling fluid containing the modified nanographene slurry anti-collapse agent are disclosed. The preparation method includes subjecting a nanographene and a mixed acid to a first contact to obtain a mixed liquid, dropwise adding potassium chlorate into the mixed liquid under the condition of ice-bath pan to carry out a modification treatment, so as to obtain a modified nanographene, and subjecting the modified nanographene to a second contact with water to prepare a modified nanographene slurry.

Methods and systems are provided for breaching a disk installed in a wellbore during oil and gas well completion and production activities. More specifically, the disclosure relates to installing and breaching a degradable disk installed in a wellbore. The degradable disk can maintain pressure within the wellbore during a wellbore procedure, such as packer installation. The degradable disk contains a nanocomposite material. The nanocomposite material includes a polymer binder and cellulose nano-fibers.

A method of treating a pipeline is performed by selecting a colloidal particle dispersion having inorganic nanoparticles with an average particle size of from 500 nm or less that exhibit properties of Brownian motion that facilitate penetration of solid deposits on interior surfaces of a pipeline. A treatment composition comprising the colloidal particle dispersion is introduced into an interior of a pipeline by at least one of (A) introducing a batch amount of the treatment composition in a selected volume into the interior of the pipeline, and (B) continuously introducing the treatment composition at a selected rate into the interior of the interior of the pipeline. The composition is allowed to act upon the surfaces and materials adhering to the surfaces of the interior of the pipeline.

A method and system for pressurizing and stimulating a formation with a parent well therethrough, the method including storing and de-liquefying liquefied natural gas (LNG) at an on-site location near the parent well, injecting a first stream of de-liquefied LNG into the parent well to pressurize the formation, and injecting a second stream of de-liquefied LNG into the parent well at a fracturing pressure sufficient to fracture the pressurized formation.
