Method and system for injecting slurry using concentrated slurry pressurization

A method of operating a slurry injection system comprising a low pressure clear fluid manifold, a high pressure clear fluid manifold, a plurality of clear fluid pumps, a blender unit, a mixer, and a slurry pressurizer comprising:

• receiving low pressure clear fluid from the low pressure clear fluid manifold at the plurality of clear fluid pumps;
• pressurizing the low pressure clear fluid into high pressure clear fluid at the plurality of clear fluid pumps;
• communicating the high pressure clear fluid into the high pressure clear fluid manifold from the plurality of clear fluid pumps;
• communicating high pressure clear fluid from the high pressure clear fluid manifold to the mixer through a first valve;
• communicating the high pressure clear fluid from the high pressure clear fluid manifold to the slurry pressurizer through a second valve;
• pressurizing, by the slurry pressurizer, low pressure slurry from the blender unit using high pressure clear fluid from the high pressure clear fluid manifold to form high pressure slurry;
• communicating low pressure fluid from the slurry pressurizer to the low pressure clear fluid manifold;
• blending, at a mixer, the high pressure slurry with high pressure clear fluid from the second valve to form a slurry mixture;
• and
• communicating the mixture to an injection site.
