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).
Claims19
A method of transporting hydrocarbon fluids, the method comprising:
- providing a kinetic gas hydrate inhibitor that comprises poly(vinyl pyrrolidone);
- 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.

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 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.
2 more elements
A method of drilling, the method comprising:
- providing a drilling fluid comprising a base fluid and a kinetic gas hydrate inhibitor that comprises poly(vinyl pyrrolidone) nanoparticles having an average particle size less than about 1000 nm;
- drilling a wellbore using the drilling fluid, the wellbore penetrating at least one zone of a subterranean formation that is at about 5° C. or less;
- and
- allowing the kinetic gas hydrate inhibitor to inhibit gas hydrate formation in at least a portion of the wellbore.
