Abstract
A slurry injection system has a plurality of slurry valves fluidically coupled to first and second elongated tanks. In the first state, the slurry valves communicate high pressure slurry from the second volume to a site and communicate low pressure slurry to the fourth volume. In the second state, the slurry valves communicate low pressure slurry to the second volume and high pressure slurry from the fourth volume to the slurry injection site and in the intermediate state communicating high pressure slurry simultaneously from the first elongated tank and the second elongated tank to the slurry injection site. In the first state clear fluid valves fluidically communicate high pressure clear fluid to the first volume and low pressure clear fluid from the third volume and, in a second state, communicate low pressure clear fluid from the first volume and high pressure clear fluid to the third volume.
