Split stream oilfield pumping systems

摘要

A method of pumping an oilfield fluid from a well surface to a wellbore is provided that includes providing a clean stream; operating one or more clean pumps to pump the clean stream from the well surface to the wellbore; providing a dirty stream including a solid material disposed in a fluid carrier; and operating one or more dirty pumps to pump the dirty stream from the well surface to the wellbore, wherein the clean stream and the dirty stream together form said oilfield fluid.

1. A method of pumping an oilfield fluid from a well surface to a wellbore comprising:
operating at least one pump to pump a diluted stream to a common manifold positioned at the well surface; operating at least one other pump to pump a concentrated stream to the common manifold, said concentrated stream comprising a proppant disposed in a fluid carrier having a proppant concentration of at least 2 pounds per gallon; and combining the diluted stream and the concentrated stream in the common manifold to form the oilfield fluid, and introducing the oilfield fluid to the wellbore.
