Abstract
A well service fluid composition comprises a fracturing fluid and a gas hydrate inhibitor. Preferably, the gas hydrate inhibitor does not affect the function of the fracturing fluid and is present in an amount sufficient to control and/or minimize the formation of gas hydrates. The well service fluid composition is useful in hydraulic fracturing in which the composition is injected into a subterranean formation under sufficient pressure to initiate and propagate a fracture in the formation. The fracturing fluid may be subsequently recovered when the fracturing operation is completed.
Claims29
A method of servicing a subterranean formation comprising:
- injecting a gas hydrate controller comprising a polyglycolpolyamine into a borehole that has been treated with a fracturing fluid.
A well service composition comprising:
- a fracturing fluid;
- and
- a gas hydrate controller, wherein:
- the gas hydrate controller is a polyglycolpolyamine;
- and
- the gas hydrate controller is in an amount effective to control the formation of gas hydrates.
A method of servicing a subterranean formation comprising injecting a gas hydrate controller comprising a polyglycolpolyamine into a borehole that has been treated with a fracturing fluid, wherein the fracturing fluid is a water-based fluid.
A method of stimulating a subterranean formation, the method comprising:
- preparing a fracturing fluid comprising an aqueous fluid, a water-soluble polymer, and a polyglycolpolyamine;
- and
- injecting the fracturing fluid into a bore hole to contact the subterranean formation.
