  • Method for determining closure of a hydraulically induced in-situ fracture
    Patent number: 5492175
    Abstract: A subsurface formation surrounding a borehole is hydraulically fractured when a fracturing fluid is supplied down through the borehole by way of a fluid injection line from the surface of the earth. Pressure drop is measured along the injection line as fracturing fluid flows therethrough. Both fracture closure and minimum in-situ stress are determined at the point where such pressure drop is equal only to a hydrostatic pressure difference along the injection line.
