Abstract
A model for predicting fracturing in shale can minimize surface disruption, protect groundwater, maximize efficiency of hydraulic fracturing, and manage fluids used in unconventional gas development. The model provides a more comprehensive understanding of the geological, geophysical, and geomechanical properties of shales and imbeds these properties in geomechanical computer simulations to predict both the reservoir performance from the fracturing, and the associated microseismic events generated by fracturing. Since the geological and geophysical properties can be estimated from surface seismic, well logs, and geologic concepts with regional context; the performance of the fracturing can be predicted and optimized. Since the microseismic events can be predicted with the model, the simulations can be verified and the model can be updated to be consistent with the observed microseismic.
