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.

Abstract: A method for directing a proppant in a subterranean formation including providing a first wellbore and a second wellbore, wherein the first wellbore and the second wellbore are disposed about a target area of the subterranean formation; creating a pressure differential between the first wellbore and the second wellbore, such that the pressure of one of the first wellbore or the second wellbore is at a higher pressure and the other of the first wellbore or second wellbore is at a lower pressure; and initiating a fracturing pressure in the higher pressure wellbore by pumping a fracturing fluid in the wellbore, the fracturing pressure sufficient to create a fracture at a predetermined location; whereby the fracturing fluid is drawn from the fractured wellbore toward the lower pressurized wellbore as a result of the pressure differential.
