Traditional water-influx calculations rely on accurate values of the van Everdingen and Hurst dimensionless variables rho/sub D/ and q/sub D/. The authors presented six sets of simple polynomials that provide a fast, simple method to determine rho/sub D/, rho/sub D'/, and q/sub D/ for finite or infinite radial aquifers. The results yield values as accurate as the original tables and are up to 15 times more efficient.
