Combining the rolls of blender, chemical van, data van and hydration unit in one set of wheels creates real efficiencies and reduces haul traffic. It minimizes the amount of equipment on location, which maximizes customer economy and use of lease space. The blend van’s chemical add pumps are hydraulically driven and controlled by Endress & Hauser flow meters, enabling automatic adjustment to clean fluid rates. A computer data acquisition system records surface data in order to provide hard copy after the job. The heated cab houses all controls for the blender, chemical pumps and chemicals. The unit is powered by two 600 hp Caterpillar C15 engines, enabling proppant concentrations up to 20 pounds per gallon (ppg) and slurry rates over 50 bbls/min.
