Phase ll of this project consisted of recording data from both the CGU21-9 and CGU22-9 seismic monitoring arrays during the production fracturing of the CGU21-9 well which took place in three stages on July 14, 16, and 18. A 48 level hydrophone array was also placed in the nearby CGU27-7 well in an attempt to collect additional data for the fracture analysis. The CGU21-9 well was one of the two original monitor wells utilized in the recording of the CGU21-10 fracture stimulation. The seismic monitoring array in the annulus of this well was recorded during its fracture stimulation in an attempt to collect data in a single well imaging configuration. date: 1997-07 publisher: Gas Research Institute institution: Gas Research Institute access_IS-EPOS: limited owner: Publisher citation: Withers, Robert J. and Dart, Robert P.
