Practical method for improving the accuracy of well test analyses through analytical convergence. T.H. Leshchyshyn, S.M. Farouq Ali and M.Y.S. Chan. J. Can. Petrol. Technol., January 1999, 38(1), 39--45.

Improved accuracy in the determination of reservoir properties is obtained by combining two independent well test analysis methods. The convergence technique is used to determine reservoir properties such as permeability when different analytical procedures are used. Equations from type-curve analysis and semilog analysis are coupled in the recommended procedure. Development of these equations is illustrated mathematically and two field examples are used to illustrate the recommended technique. The method has a broad scope of application and can be used in other areas of practice and investigation. 6 refs.
