Abstract:
Methods and apparatus are disclosed for mixing proppant and other solids with one or more fracturing fluids to form a fracturing slurry, and for delivering the fracturing slurry to a wellbore. In the example systems as described herein, the proppant is mixed with the fracturing fluids through an assembly that limits the number of pumps that are required to move the relatively abrasive proppant]containing fluids. Additionally, in the example systems, the proppant is mixed within enclosed structures, thereby minimizing the escape of dust and other particulates into the surrounding atmosphere and onto the equipment at the well site.

Claim (Index 11):
A proppant delivery system, comprising:\n an in-line mixer located at the Earth's surface and coupled directly to a wellhead tree of a well; a proppant delivery circuit coupled to transport proppant through an enclosed passageway to an in-line mixer located at the Earth's surface, the proppant delivery circuit including,\n an enclosed proppant mixer coupled to receive proppant and at least one fluid, and having a mixing mechanism to mix the fluid and proppant to form a fluidized proppant mixture, and \n a first pump coupled between the enclosed proppant mixer and the in-line mixer, and operable to pump the fluidized proppant mixture to the in-line mixer; \n a fluid delivery circuit coupled to transport proppant-free fracturing fluids to the in-line mixer, the fluid delivery circuit including at least a second pump that is separate from the first pump, and is placed upstream of the in-line mixer.
