Abstract
Inhibiting gas hydrate formation while transporting hydrocarbon fluids may include providing a kinetic gas hydrate inhibitor, adding the kinetic gas hydrate inhibitor to a fluid capable of producing gas hydrates, and transporting the fluid that comprises the kinetic gas hydrate inhibitor. Generally a kinetic gas hydrate inhibitor may include a heterocyclic compound comprising nitrogen, e.g., poly(vinyl pyrrolidone).
Claims17
A method of producing hydrocarbons, the method comprising:
- providing a treatment fluid comprising a base fluid and a kinetic gas hydrate inhibitor that comprises a rubber latex and a heterocyclic compound comprising nitrogen;
- introducing the treatment fluid into a wellbore penetrating a subterranean formation, wherein at least one zone of the subterranean formation is about 5° C. or less;
- producing hydrocarbons from the subterranean formation;
- and
- allowing the kinetic gas hydrate inhibitor to inhibit the formation of gas hydrates.

A method of producing hydrocarbons, the method comprising:
- introducing a treatment fluid into a wellbore penetrating a subterranean formation, wherein at least one zone of the subterranean formation is about 5° C. or less, the treatment fluid comprising a base fluid and a kinetic gas hydrate inhibitor that comprises crosslinked poly(vinyl pyrrolidone) in the form of nanoparticles having an average particle size less than about 1000 nm;
- producing hydrocarbons from the subterranean formation;
- and
- inhibiting the formation of gas hydrates with the kinetic gas hydrate inhibitor.
