ABSTRACT:
The present invention is generally directed to a method for determining certain parameters necessary for fracture treatment design. The method and analysis of the present invention provide for calculation of the product of the fluid-loss coefficient and the fracture half length or the square of fracture radius. The test disclosed in this invention does not generally require the assumption of a fracture geometry and does not require the assumption of a fracture height. The information gained from performing this test may be used to properly design fracture treatments for any given well. In addition, the method of the present invention may be used in conjunction with the methods currently known in the art to provide more information than any of the methods individually.
