HYDRAULIC IMPEDANCE TEST METHOD

摘要

Case 7141(2) HYDRAULIC IMPEDANCE TEST METHOD A method for determining the height and length of a fracture (3) in a borehole (1) involves generating pressure waves in the fluid in the wellbore using a valve (4) and measuring the response at the wellhead by means of a transducer (5). A theoretical model of the wellbore-fracture system is generated and compared with the measured response to determine the height and length of the fracture.
