Abstract:

This paper makes a research on the mathematical model of productivity prediction in view of the four completion methods or horizontal wells of perforation series, such as casing perforated completion, inside casing wire wrapped screen, inside casing gravel pack, inside casing prepacked gravel liner and in consideration of the effect of formation damage, well completion methods and well completion parameters on the productivity of horizontal wells. Example calculation shows these mathematical models and their calculation methods are feasible and can be used in the optimum selection of well completion methods and the optimum design of well completion engineering.

Key words: Well completion method, Perforated completion, Perforated efficiency, Horizontal well, Productivity prediction
