Abstract
A system and method for injecting slurry includes a first elongated tank comprising a first end having a first volume and a second end having a second volume, said first volume separated from the second volume, a first pipe having a first end external to the first elongated tank receiving clear fluid and a second end coupled to the first volume and a plurality of slurry valves fluidically coupled to the first elongated tank. The plurality of slurry valves have a first state communicating high pressure slurry from the second volume to the slurry injection site and a second state communicating low pressure slurry into the second volume. A plurality of clear fluid valves are fluidically coupled to the first elongated tank and communicate high pressure clear fluid to the first volume in the first state and communicate low pressure clear fluid from the first volume in the second state.
