Micro-Seismic Monitoring of Fracture Stimulation

Our long arrays placed in deep monitor wells, or shallow purposely-drilled monitor wells, allow for the recording and better identification of more events than standard services. Traditional methods only measure a small portion of the incident wavefield, resulting in mislocation of the loci of the event. Our processing techniques require only the identification of a P-wave or S-wave, but not both. Competitor methods require the identification of a match pare of both P-wave and S-wave to locate an event. Small magnitude events may generate only a very low amplitude S-wave, for example. As you can see, the GT partnership technique allow for the ability to detect and accurately locate significantly more micro-seismic events than the competitors methods.
