A kinetic gas hydrate inhibitor is provided as a polyester polymer with a plurality of amino or ammonium groups pendent directly from the backbone. A composition containing concentrated kinetic inhibitor is injected into gas wells, or into other systems involving transporting liquid gas mixtures through a conduit. Use of the kinetic inhibitor prevents formation of gas hydrates under conditions of temperature and pressure where they would otherwise occur.

Certain particulates of encapsulated treatment chemicals, and methods of and systems for their use in subterranean formations, are provided. In one embodiment, the methods comprise: providing a plurality of treatment particulates, at least one of which comprising a polymer matrix that comprises and/or encages at least one treatment chemical and a coating disposed around an outer surface of the polymer matrix; and introducing the treatment particulates into a well bore penetrating at least a portion of a subterranean formation.

A binary mixture system for lower oil viscosity and increased oil flow. The binary mixture composition may be useful for introduction into a functioning oil reservoir for cleaning and stimulation. The binary mixture composition is made of a first-chemical composition, a second-chemical composition, and a third-chemical composition. The first-chemical composition may be ammonium nitrate-water. The first-chemical composition may have a ratio of 1.0 to the second-chemical composition and the third-chemical composition. The first-chemical composition may be heated to a temperature of sixty degrees celsius. The second-chemical composition is made of the sodium nitrite-water. The second-chemical composition may have a ratio of 1.56 to the first-chemical composition and the third-chemical composition. The second-chemical composition may also be heated to a temperature of sixty degrees celsius. The third-chemical composition is made of phosphoric acid-water. The third-chemical composition may have a ratio of 0.2 to the first-chemical composition and the second-chemical composition.
