System for containment, measurement, and reuse of fluids in hydraulic fracturing

A system of fluid containment for use in hydraulic fracturing (fracking), the system comprising:

• a plurality of fluid containment structures configured to store fluid, each fluid containment structure comprising a flexible body;
• a first fluid transportation structure coupled to the first fluid containment structure;
• a second fluid transportation structure coupled to the second fluid containment structure;
• a backflow preventer comprising:
• a forward port coupled to the first fluid transportation structure and configured to receive drilling fluid from the first fluid containment structure,
• a primary port coupled to a well, the primary port configured to provide the drilling fluid to the well and receiving waste fluid from the well,
• a return port coupled to the second fluid transportation structure and configured to provide the received waste fluid from the well to the second fluid transportation structure, and
• a flow control mechanism to substantially prevent the flow of waste fluid through the forward port and substantially prevent the flow of drilling fluid through the return port and the return port alternately couples with the primary port to provide the drilling fluid to the well and receive the waste fluid from the well;
• and
• a monitoring system comprising:
• a first flow meter coupled to the forward port of the backflow preventer configured to transmit a first signal corresponding to a volume of drilling fluid received from the first fluid containment structure,
• a second flow meter coupled to the return port of the blackflow preventer configured to transmit a second signal corresponding to a volume of waste fluid provided to the second fluid containment structure, and
• a third flow meter coupled to the first fluid containment structure configured to transmit a third signal corresponding to a volume of drilling fluid received at the first fluid containment structure.
