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.

An omniphobic emulsion comprising an aqueous continuous phase having dispersed therein a plurality of non-aqueous discontinuous phase droplets; wherein the non-aqueous discontinuous phase droplets are characterized by a droplet size of less than about 100 micrometers (μm); wherein each of the plurality of non-aqueous discontinuous phase droplets comprises a plurality of surfactant molecules and an omniphobic agent, wherein each surfactant molecule has a hydrophilic head portion and a hydrophobic tail portion; wherein each of the plurality of non-aqueous discontinuous phase droplets comprises the plurality surfactant molecules having the hydrophilic head portions disposed into a droplet outer layer with the hydrophobic tail portions extending inward from the droplet outer layer toward the omniphobic agent; and wherein the droplet outer layer encloses the omniphobic agent.

An acid treatment composition includes a nonionic surfactant, including nonyl phenol ethoxylate. The acid treatment composition also includes a retarding agent comprising magnesium, an acid, and water. The nonionic surfactant and retarding agent of the acid treatment composition are reactive with carbonate.

A method for acid treatment of a wellbore in a carbonate formation is provided. The method includes dropping spacer solids into the well to fill the wellbore to perforations in a casing, dropping acidic solids into the wellbore on the top of the spacer solids, allowing the acidic solids to dissolve on top of the spacer solids forming an acidic solution, and injecting water into the wellbore to force the acidic solution into the carbonate formation.

A crosslinked polymer comprising reactants of a first repeating unit, a second repeating unit, and a crosslinker that react to form the crosslinked polymer, wherein the first repeating unit is a sulfonic acid-containing monomer present from 50% to 99% by weight of the reactants, wherein the second repeating unit is selected from the group consisting of an N-vinyl amide-containing monomer, a terminal double bond-containing monomer, and any combination thereof, and is present from 1% to 50% by weight of the reactants, and wherein the crosslinker comprises at least two olefinic bonds, and is present in the range of about 9% to about 25% by weight of the reactants.

The present invention relates to aqueous compositions for forming a foam, comprising a surfactant and a particulate inorganic material, and optionally one or more polymers, such as soil conditioning polymers, and/or viscosity increasing polymers. The present invention further relates to the use and application of said aqueous compositions.

A method includes injecting an aqueous-based injection fluid into a wellbore at a first temperature, where the aqueous-based injection fluid includes phase-changing nanodroplets having a liquid core and a shell. The method also includes exposing the phase-changing nanodroplets to a second temperature in the wellbore that is greater than or equal to a boiling point of the liquid core to change a liquid in the liquid core to a vapor phase and expand the phase-changing nanodroplets, thus removing debris from the wellbore and surrounding area.

Clay stabilization compositions include one or a plurality of triamino compounds and/or derivatives thereof, fluids containing an effective amount of the clay stabilization compositions and methods for making and using same.

The subject invention provides microbe-based products, as well as their use to improve oil well production and increase the value of heavy crude oil. Specifically, the subject invention provides cultivated yeast products, which can be applied to oil and/or oil and gas production equipment to improve production and increase the economic value of heavy crude oil by, for example, upgrading heavy oils and/or converting heavy hydrocarbon substances, such as asphalts, asphaltenes, tars, bitumens and/or petcokes into lighter hydrocarbon substances.
