Reservoir Modeling and Production Evaluation in Shale-Gas Reservoirs

This paper examines issues with forecasting and evaluating production from unconventional gas reservoirs, such as the<br>Barnett Shale. How can reservoirs be commercial with matrix permeability measured not in milli-Darcy or even micro-Darcy<br>(10-3 mD), but as low as 10-100 nano-Darcy (10-6 mD)?
