An example of practical application of information on fracturing according to the well logging data complex and high-tech methods

Abstract

In the article the issue of investigation by logging methods of reservoirs with natural fracturing is considered. A special case of revealing the reason for fast watering of productive layers with the help of a logging data complex and high-tech methods, such as: cross-dipole acoustic logging, acoustic scanner, electric micro-imager is considered. Scanners allow us to get an image of the inner surface of the well wall in order to reveal fractures. Measurement of the propagation characteristics of acoustic waves is used to detect fractures. Complex interpretation led to the conclusion that the watering is due to the presence of sub-vertical fractures associated with the underlying aquifers.
