  • Hydraulic fracturing method
    Patent number: 6981549
    Abstract: The present invention relates to methods of designing a hydraulic fracturing treatment in a subterranean reservoir and methods of treatment. Methods of the invention include quantifying reservoir parameters such as bottomhole temperature and formation permeability, then assessing the temporary variation in temperature of the formation due to the injection of calibration and/or clean up fluids. Treatment fluids are then design based upon the temporary temperature. The fluids are then pumped to treat the reservoir.
