Abstract
A system and method for injecting slurry includes first and second elongated tanks. Tanks include pipes extending therefrom. Slurry valves and clear fluid valves are fluidically are coupled the first and second elongated tanks. Slurry valves have a first state communicating high pressure slurry from a second volume of the first tank to the injection site and communicating low pressure slurry to a fourth volume of the second tank, and a second state communicating low pressure slurry to the second volume and high pressure slurry from the fourth volume to the injection site. The clear fluid valves communicate pressurized clear fluid to the first volume of the first tank and communicate low pressure clear fluid from the third volume of the second tank in a first state and communicating low pressure clear fluid to the first volume and pressurized clear fluid to the third volume in a second state.
