  • Reconditioning process for used hydrocarbon based stimulation fluid
    Patent number: 8088275
    Abstract: A process treats a fluid stream of used fracturing fluid containing contaminants and forms a reconditioned fluid stream. Contaminants are removed by the combination of distillation, electrostatic agglomeration, decanting, and filtration or by distillation and optional filtering. Optionally, in each case, the filtered fluid stream is treated in a clay tower to remove residual contaminants.
    Type: Grant
    Filed: May 16, 2008
    Date of Patent: January 3, 2012
    Assignee: Gibson Energy ULC
