Different pore sizes will exhibit different flow regimes inside the reservoirs, and thus it is important to be able to model flow though different...

... Beskok and Karniadakis (1999) have pointed out that the first-order Maxwell model is insufficient to represent the velocity profile beyond the slip flow regime. In contrast, the second-order velocity model is competent to cover full flow regimes, and various empirical slip coefficients have...

... information in our Denton County - Barnett shale data set, we identified 55 wells that began to produce between September 2003 and March 2012 and that had reached BDF. We also identified 77 wells still in the transient flow regime. Type Well Construction and Forecasts for Wells in BDF To estimate...

...Background of Echo State Network Abstract Production data analysis for low permeability shale reservoirs is crucial in characterizing flow regimes and reservoir properties, and the forecasting of production is essential for portfolio and reservoir management. However, traditional methods...

... Abstract Decline curve analysis (DCA) is the most common method to forecast future production and to estimate ultimate recovery and reserves/well. The traditional form of DCA proposed by Arps is however restricted to boundary-dominated flow regimes. In unconventional shale plays, it is however...
