Split stream oilfield pumping systems

A system for pumping an oilfield fluid from a well surface to a wellbore, said system comprising, at the well surface:

• a water source comprising a water tank at the well surface for supplying water to at least one of the first stream and second stream;
• a first stream comprising water from the water source;
• a second stream comprising a fiber;
• a common manifold that is connected to the first stream and the second stream, said common manifold combining the first stream and the second stream to form the oilfield fluid;
• and
• at least one pump at the well surface for pumping the first stream to the common manifold, wherein said at least one pump is directly connected to the water tank at one end and to the common manifold at another end.
