... of errors on the predicted total fracture surface area caused by the constant permeability assumption. The study proposes a modified RTA model, which accounts for dynamic permeability to eliminate the error in calculated area. Results from the sensitivity analysis show that the error on surface area...

... and reservoir properties can change significantly throughout the production period. Since the commonly used analyses are largely based on the assumption of constant properties, the central question of this study is: For RTA purposes, is it valid to assume that the variation of oil and reservoir properties...

... assumptions. Different options to turn a continuous fracture distribution into a given number of discrete levels are investigated. Eventually, based on dimensionless coefficients, an optimal number of fracture scales is determined by lumping levels with similar behaviour. Rate-limiting transfer occurs between...

In a detailed dimensional analysis of the Navier-Stokes equation dimensionless groups are formed, the magnitude of which determines...
