摘要:
Low residue, high salinity fracturing fluids may be produced by hydrating a gelling agent comprising carboxymethyl hydroxypropyl guar (CMHPG) in an aqueous fluid having a total dissolved solids concentration of about 30,000 ppm or greater and a pH of about 5 to about 8; adjusting the pH of the aqueous fluid to about 9 to about 10; and then, adding a zirconate crosslinker to the aqueous fluid to yield a crosslinked-CMHPG
摘要:
Products, methods and processes for manufacture that are related to application fluid, more specifically, to oil field compositions that include a fracturing fluid composition prepared by a process including at least the steps of:—contacting a polysaccharide particle with water to produce process water, and—separating the process water from the polysaccharide particle, whereby the separated process water comprises at least part of the fracturing fluid composition.
摘要:
Disclosed herein is a fracturing fluid including a carrier fluid and a viscosity-increasing self-breaking synthetic polymer soluble in the carrier fluid. A method for treating a hydrocarbon-bearing formation is also disclosed.
摘要:
A fracturing fluid and method of including a cellulose polymer derivative, a diol functional group, and a borate crosslinker. The diol functional group may be a cis-diol functional group, a 1,2-diol functional group, or a 1,3-diol functional group. The cellulose polymer derivative further may include a hydroxyethyl group or a hydroxypropyl group. The fracturing fluid may also include at least one metallic crosslinker. The method may also include the steps of adding a pH adjusting agent, at least one breaker, a surfactant, a scale inhibitor, and/or a bactericide to the fracturing fluid, or mixing the fracturing fluid using mixing equipment or wherein the fracturing fluid is introduced into a subterranean formation using one or more pumps.
摘要:
Embodiments herein include methods comprising introducing a treatment fluid into a subterranean formation, wherein the treatment fluid comprises a base fluid, an acid, and a fluoride releasing agent selected from the group consisting of an amine monofluorophosphate; a bisamine monofluorophosphate; any derivative thereof; and any combination thereof, wherein the acid and the fluoride releasing agent react to generate hydrofluoric acid over time in the subterranean formation so as to create or enhance at least one microfracture therein.
摘要:
A method of treating a portion of wellbore comprises: introducing a treatment fluid into the portion of the wellbore, wherein the treatment fluid comprises: a base fluid; and an additive comprising a plurality of fibrillated fibers, wherein the amount of fibrillation is at least sufficient such that at least a portion of the fibrillated fibers form a fiber network in the base fluid.
摘要:
The invention relates to use of masterbatches containing high concentrations of antimicrobial materials such as copper salts, particularly copper iodide. These masterbatch compositions are added to other materials which are used to form various articles of manufacture with antimicrobial properties. The copper salts may be incorporated in the masterbatches as surface functionalized particles or the salts may be incorporated into porous particles prior to the formation of masterbatches.
摘要:
Systems and methods for creating and/or using multi-functional surfactant complexes that may enhance surfactant treatments in subterranean formations are provided. In some embodiments, the methods comprise: providing a treatment fluid comprising an aqueous base fluid and one or more multi-functional surfactant complexes that comprise at least one surfactant and at least one polymeric additive, wherein the surfactant and the polymeric additive carry opposite charges; and introducing the treatment fluid into a well bore at a well site penetrating at least a portion of a subterranean formation.
摘要:
Methods for the use of peracid compositions having decreased hydrogen peroxide concentration for various water treatments, including oil- and gas-field operations, and/or other aseptic treatments are disclosed. In numerous aspects, peracetic acid is the preferred peracid and is treated with a peroxide-reducing agent to substantially reduce the hydrogen peroxide content. Methods for using the treated peracid compositions for treatment of drilling fluids, frac fluids, flow back waters and disposal waters are also disclosed for improving water condition, reducing oxidizing damage associated with hydrogen peroxide and/or reducing bacteria infestation.
摘要:
The present invention relates to systems and methods for the on-site generation (for example at oil well drilling operations, oil well hydraulic fracturing operations, makeup water pipeline transportation systems, and oil and gas refining operations) of haloamine chemistry such as chloramines and/or bromamines. The invention also relates to the application of the generated haloamines to control microorganisms such as bacteria as well their harmful byproducts such as hydrogen sulfide and other undesired substances found in oil and gas industries.
