High-quality surface microseismic data illuminates fracture treatments: A case study in the Montney

摘要

The microseismic results from these two wells showed that pre-existing fracture trends were an important control on the behavior of the fracture stimulation in this program. Where the pre-existing fractures did not exist, primarily in the upper Montney, frac events typically were recorded only after proppant pumping began and the number of events appears to correlate with proppant concentration. Stimulation of the preexisting fracture trends in or below the Lower Montney layer resulted in microseismic events that began as soon as frac fluid was pumped into the formation.
