Imaging breakthrough promises more reliable SRV calculations

摘要

Accurate evaluation of the volume of a reservoir that has been effectively stimulated by fracturing operations is central to generating returns from unconventional resources. Stimulated reservoir volume (SRV) is a critical factor in resource plays and is used by engineers to assess the effectiveness of a fracture treatment, establish parameters for future frac stages, and compute decline curves for quantifying bookable reserves. However, estimates derived from widely used imaging approaches come with significant limitations and uncertainties and often result in SRV being overestimated. Another issue is that the same data analyzed by different processors can generate widely differing results, which leads some engineers to question the value and integrity of the information microseismic analysis is delivering.
