Title: HIGH TEMPERATURE GRAVEL PACK FLUID
Abstract:
Gravel pack fluids and methods of use thereof provides improved fluid suspension characteristics under extremely high temperatures, for example, from about 275°F to 300°F (135°C to 149°C) or higher. The disclosed the gravel pack fluids are able to achieve stability at these elevated temperatures by virtue of a gel composition having natural or synthetic hectorite nanoparticles added thereto. Such gravel pack fluids are especially useful for delivering proppant into a subterranean formation, gravel into a wellbore, and the like, in certain parts of the world known to have extremely high downhole temperatures. The disclosed gravel pack fluids are particularly useful for inclined and horizontal well applications, as well as applications that involve transporting particulates through alternate flow paths, such as shunt tubes, bypass conduits, and the like.
