  • Polymer flood filtration improvement
    Patent number: 4212748
    Abstract: Filterability of aqueous solutions of polymers employed to thicken waterfloods such as biopolymers (e.g. heteropolysaccharides) is improved by addition of a surfactant (e.g. a sulfated alkoxylated alcohol). Filterability is further enhanced by addition of an ethoxylated alcohol surfactant and/or an alcohol.
    Type: Grant

  • Method and apparatus for automatic control of filtrate quality
    Patent number: 4107037
    Abstract: A sidestream of injection liquid taken downstream of a filter is passed through a monitoring filter of appropriate pore size. Pressure drop over the monitoring filter is determined and a regeneration cycle for the main filter is triggered in response to differential pressure (.DELTA.P) over a preset value, which corresponds to deterioration in filtrate quality.
