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.

Abstract: A mechanism for improving speed of table model-based simulation of complex circuits that include transistors and other devices that share similar properties is provided. Circuit simulation speed is improved by efficiently identifying transistors and other devices having substantially the same properties that share a same state at the time of interest in the simulation. Transistors and other devices are collected into groups having the same characteristics and topologies prior to simulation. Then during simulation, a determination is made as to whether a previously-evaluated transistor or device in the same group as a presently-being evaluated transistor or device has terminal input values that are the same, or nearly the same. If so, a cache lookup is performed to determine table model solution values for the previously-evaluated transistor or device, and those values are used to determine exact output values per the table model of the presently being evaluated transistor or device.
