Abstract
A blending unit is provided. The blending unit comprises two or more discharge pumps. Each of the two or more discharge pumps has a suction inlet fluidly connected to a common proppant fluid supply via a concentrated proppant inlet line, and a discharge outlet fluidly connected to a blender outlet line. Each of the two or more discharge pumps also has an injection port upstream of the discharge pump and configured to inject substantially proppant-free fluid into the concentrated proppant inlet line, an injection port downstream from the discharge pump and configured to inject substantially proppant-free fluid into the blender outlet line, or both the injection port upstream of the discharge pump and the injection port downstream from the discharge pump.
Claims23
A blending unit comprising:
- a first discharge pump downstream from a blender tub and having a suction inlet fluidly connected to the blender tub via a concentrated proppant inlet line, a discharge outlet fluidly connected to a blending unit outlet line, and (i) an injection port upstream of the first discharge pump and downstream from the blender tub and configured to inject substantially proppant-free fluid into the concentrated proppant inlet line, (ii) an injection port downstream from the first discharge pump and configured to inject substantially proppant-free fluid into the blending unit outlet line, or (iii) both the injection port upstream of the first discharge pump and downstream from the blender tub and the injection port downstream from the first discharge pump;
- a first substantially proppant-free supply pump having a suction inlet fluidly connected to a substantially proppant-free fluid supply source and a discharge outlet fluidly connected to (i) the injection port upstream of the first discharge pump and downstream from the blender tub, (ii) the injection port downstream from the first discharge pump, or (iii) thereof;
- and
- a second substantially proppant-free supply pump having a suction inlet fluidly connected to the substantially proppant-free fluid supply source and a discharge outlet fluidly connected to (i) the injection port upstream of the first discharge pump and downstream from the blender tub, (ii) the injection port downstream from the first discharge pump, or (iii) a combination thereof.
