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： Methods and compositions useful for subterranean formation treatments, such as hydraulic fracturing treatments and sand control that include porous materials. Such porous materials may be selectively configured porous material particles manufactured and/or treated with selected glazing materials, coating materials and/or penetrating materials to have desired strength and/or apparent density to fit particular downhole conditions for well treating such as hydraulic fracturing treatments and sand control treatments. Porous materials may also be employed in selected combinations to optimize fracture or sand control performance, and/or may be employed as relatively lightweight materials in liquid carbon dioxide-based well treatment systems.
