... monitoring. Compared to vendor?s fixed isotropic velocity model results, we not only improved microseismic event locations, but also updated anisotropic velocity model. The mean of arrival time residuals has been reduced by 40%, which implies more accurate event locations, thus can help optimize well...

... here address the idea of the use of weak anisotropy approximation for microseismic events location. For homogeneous models it was shown that the use of weak anisotropy approximation does not causes severe shifts in microsesimic events locations. On the other hand in case of strong media anisotropy...

... data to form images of the subsurface structure. Microseismic events give rise to both P and S wave arrivals. These arrivals scatter off structures in the vicinity of the microseismic event location. By referencing S arrivals with respect to P arrivals and by tracking these P and S events back through...

To overcome this problem we present a location workflow that in addition to arrival times takes into account polarizations of the P-wave as well as crosscorelations between microseismic recordings. We show how this updated workflow improves...
