CASE STUDY Application of Sonic Geomechanics for Engineered Completions in Unconventional Reservoirs As operators gain more experience producing unconventional reservoirs, many have come to realize that lateral heterogeneity within the formation should not be ignored. Variability in the stress profile along the lateral impacts the completion design and, if unaccounted for, can lead to significant inefficiency in the completion and the resulting production. The current best-in-class approach to mitigating this problem is to estimate the stress profile using wireline tools that make full-waveform sonic measurements. These measurements are used as inputs to a sonic geomechanics workflow to estimate properties such as unconfined compressive strength (UCS), stress profile and brittleness
