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).
Claims13
A method of drilling, the method comprising:
- providing a drilling fluid comprising a base fluid and a kinetic gas hydrate inhibitor, the kinetic gas hydrate inhibitor comprising a rubber latex and a heterocyclic compound comprising nitrogen;
- 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.
