Development of a 2000 horsepower fracturing pump unit has brought greater safety, more reliability, more sand pumping capacity, reduced manpower requirements, and shorter setup time to fracturing operations. The pump is a crankshaft type, powered by a 16-cylinder diesel engine, and driven through an eight speed transmission. For job control, the unit is provided with remote controls and a specialized pressure limiting system. The fluid end has been optimized for handling fluids with high sand concentrations. The paper describes the design and gives pertinent specifications of the pumping unit. Selected case histories from more than a year of operation are presented, including accounts of stimulation jobs where record-high sand concentrations were pumped. Job design considerations peculiar to the use of this large-scale pumping capability are presented.
