Abstract: Aspects of a pressure and flow balanced frac tank farm are described herein. In one embodiment, a frac tank farm includes at least one battery of frac tanks comprising a plurality of frac tank trailers, a header pipe arrangement, and at least one valve between one or more of the frac tank trailers and the header system. The header pipe arrangement may include a header supply pipe to supply water to individual ones of the plurality of frac tank trailers and a header discharge pipe to discharge water from individual ones of the plurality of frac tank trailers. The header pipe arrangement may be relied upon to help balance the flow of heated fluids among the frac tank trailers. Further, the frac tank farm may include pressure balancing end pipes and a balancing header pipe arrangement to help balance fill levels and water pressure among frac tank trailers.

Abstract: A configuration management system which generates and updates its own real-time dynamic database for representing a system configuration. The configuration management system includes an user interface for receiving user input of free-hand graphic drawings representing system configuration changes. The configuration management system further includes an interactive graphic interpretive and linking actuator which employs the user input of free-hand graphic drawings representing the system configuration changes for linking to sections of the database corresponding to the user input of configuration changes and updating data stored therein thus representing a new system configuration updated by the user input of the configuration changes. The user interface future includes a dialog box for receiving system parameters relating to the user input of free-hand graphic drawings representing the system configuration changes.
