METHOD OF GEOMETRIC EVALUATION OF HYDRAULIC FRACTURES

摘要

A method of evaluating a geometric parameter of a first fracture emanating from a first wellbore penetrating a subterranean formation is provided. The method includes the steps of forming the first fracture in fluid communication with the first wellbore; forming a second fracture in fluid communication with a second wellbore, the second wellbore in proximity to the first wellbore; measuring a first pressure change in the second wellbore; and determining the geometric parameter of the first fracture using at least the measured first pressure change in an analysis which couples a solid mechanics equation and a pressure diffusion equation.
