Surface microseismic in an extreme environment

A surface microseismic survey was conducted in a noisy suburban active oil-field environment. Unconventional patch acquisition survey design and careful processing allowed the extraction of more than 8000 events from the noisy data. Patch acquisition and multichannel noise attenuation were critical components of the success of the project. The computation of microseismic source mechanisms from the surface depended on solving for accurate velocities and statics in the preprocessing stage.
