SAND PREDICTION
We provide sand prediction analyses based on foot-by-foot assessment of log-derived mechanical properties, tied closely to reservoir sand strength measurements from laboratory tests and foot-by-foot predictions of the in situ stress state. Our StressWell tool permits sand failure assessments using the full three-dimensional stress state, transformed into wellbores or perforations of any orientation.
