Abstract Microseismic monitoring provides good spatial and temporal information about hydraulic-fracture development in unconventional reservoirs, but it is insufficient by itself to define all the important characteristics of the created fracture system. Other diagnostics can aid in interpretation of fracturing, particularly with respect to volumetric distribution (using microdeformation) and near-wellbore conditions (using fiber optics). The ultimate goal is a better understanding of the effectively producing system through a combination of diagnostics and modeling.
