... of the perforation within a stage. Perforations shot through casing connections are reviewed, with aggregated damage statistics indicating major differences in damage severity between premium and non-premium connection types. A particular pattern of casing damage consistently located at a phasing of 180 degrees...

... P- and S-waves. The highest quality events direct P- and S- waves arrivals times, were used for velocity model building. The key differentiator of our processing is that we built the velocity model based on both perforation shots URTeC 5517 4 and microseismic events. This process is described...

... velocity model is required to accurately locate microseismic events. An initial velocity model is usually built using a sonic log, and then calibrated using perforation shots with known locations. The calibration process involves identifying P-waves and/or S-waves generated by the perforation shots...

... plays a key role in obtaining event location. However, due to the limited number of perforation shots, limited ray coverage, and identifying / classifying different phase arrivals in the perforation data, building a reasonable velocity model is very challenging. In this paper, we present a field case...

... estimates are extracted from perforation data which adds interpretative value. Introduction Perforation shots are typically used in conjunction with apriori velocity information derived from sonic well logs to build a velocity model suitable for mapping microseismic events. These models typically...

... arrivals were used instead of the conventional P-wave polarization to estimate microseismic event location. A Bayesian inference program was also developed for joint event location and velocity model calibration. Validation of the developed method was performed on perforation shots and shows that using...
