Integrated analysis predicts sweet spots

摘要

A study of microseismic and seismic reflection leads to success in the Montney shale. Experience has shown that shale production and recovery rates from hydraulic fracturing vary unpredictably, not only from one well to another but also from one fracture stage to the next along a single borehole. Why? For one thing, the material properties of shale reservoir rocks naturally exhibit high levels of vertical and lateral heterogeneity. In addition, local stress fields, pore pressures, and preexisting fractures or faults within or near the reservoir can have a significant impact on the variability of fracture stimulations.
