A method and system are provided for preparing a fracturing fluid for a fracture treatment in a subterranean formation using different types of fluids. A first mixture, formed with a consistent quality fluid and proppant, is combined with a second mixture, formed with an inconsistent quality fluid, to create a combined fracturing fluid. Each of the first and second mixtures may be pressurized and combined for use in one or more stages of a fracture treatment. The consistent quality fluid may comprise a new or high quality fluid and the inconsistent quality fluid may comprise a low quality fluid, such as fluid recovered or recycled from a previous fracturing treatment. Chemicals may be added to one or both mixtures. Quality measurements may be obtained for the second mixture. Independent monitoring and control of system allow for the preparation of a fracturing fluid with predetermined qualities.
