    摘要: A nano-dispersion well servicing fluid is formulated with components comprising: nanoparticles comprising at least one material chosen from aluminum oxides, aluminum hydroxides, aluminum hydroxyoxides, zirconium oxides, zirconium hydroxides, zirconium hydroxyoxides, wherein the concentration of nanoparticles is greater than 0.5% by weight based on the total weight of the nano-dispersion well servicing fluid. The well servicing fluid also comprises an aqueous base continuous phase. Methods of employing the nano-dispersion to service a wellbore are also disclosed.

    摘要: Crosslinking of a crosslinkable viscosifying agent and a crosslinking agent may be delayed in a well treatment fluid by incorporated within the fluid a glutamic-N,N-diacetic acid salt, such as a glutamic-N,N-diacetic acid sodium salt like tetrasodium glutamate diacetate. The crosslinking agent may be a zirconium containing crosslinking agent like zirconium (IV) acetyl acetonate. The viscosifying agent may be guar or a guar derivative such as carboxyalkyl guars and hydroxyalkylated guars like carboxymethyl guar, hydroxypropyl guar, hydroxyethyl guar, hydroxybutyl guar and carboxymethylhydroxypropyl guar.

    摘要: Spherical porous and non-porous cellulose particulates for use in sand control as well as stimulation procedures, may be prepared by first dissolving cellulosic materials (such as fibrous cellulose, wood pulp linters, cotton balls and/or paper), in the substantial absence of water or a nitrogen-containing base, in an ionic liquid. The solution is then combined with a cellulose-insoluble liquid to render the spherical particulates. The surface of the cellulosic particulates may be treated with a coating or penetrating layer.

    摘要: Hydraulic fracturing is conducted by use of a well treatment fluid which contains a guar gum derivative as viscosifying or gelling polymer, an organic zirconate complex of a zirconium metal and an alkanol amine as crosslinking agent and a salt of a hydroxylated glycine as crosslinking delaying agent. The fluid is characterized by a low pH, generally greater than or equal to 3.0 and less than or equal to 5.0.
