Abstract
A slurry injection system having a plurality of clear fluid pumps receiving clear fluid from a low pressure clear fluid manifold and pressurizing the clear fluid into high pressure clear fluid and communicating the high pressure clear fluid into the high pressure clear fluid manifold. A blender unit having low pressure slurry therein. A mixer receives clear fluid through a first valve. A slurry pressurizer in fluid communication with the high pressure clear fluid manifold through a second valve. The slurry pressurizer forms high pressure slurry by pressurizing the low pressure slurry from the blender unit using high pressure manifold clear fluid that is communicated to the mixer and communicates low pressure fluid to the low pressure clear fluid manifold. The mixer mixes the high pressure slurry and clear fluid from the first valve to form a mixture that is communicated to a slurry injection site.
