Abstract
The detailed analysis of cross well seismic data for a gas reservoir in Texas revealed two newly detected seismic wave effects, recorded approximately 2000 feet above the reservoir. A tube-wave () is initiated in a source well () by a source (), travels in the source well (), is coupled to a geological feature (), propagates () through the geological feature (), is coupled back to a tube-wave () at a receiver well (), and is and received by receiver(s) () in either the same () or a different receiving well (). The tube-wave has been shown to be extremely sensitive to changes in reservoir characteristics. Tube-waves appear to couple most effectively to reservoirs where the well casing is perforated, allowing direct fluid contact from the interior of a well case to the reservoir.
