  • Methods of improving conformance control in fractured hydrocarbon reservoirs
    Patent number: 7475727
    Abstract: Three methods for improving the blocking ability of gels by improving the performance of gels in fractured reservoirs are provided. First method utilizes overload of a crosslinker, the second method utilizes a combination of crosslinker overload and aged crosslinker, and the third method utilizes a step of crosslinker pre-flush. These methods may be combined to further improve the performance of gels in fractured reservoirs. All methods utilized Chromium (III) acetate as a crosslinker. These methods outperformed the base formula of Chromium/polymer typically used in the field.
