A well screen assembly (70) with a controllable variable flow area. The well screen assembly (70) comprises an outer tubular section (80), the outer tubular section (80) containing a first plurality of openings (90) disposed in a pattern (100) throughout a length "L" of the outer tubular section (80); an inner tubular section (110) that is disposed within the outer tubular section (80), the inner tubular section (110) containing a second plurality of openings (120) disposed in the same pattern (100) throughout a length L of the inner tubular section (110), and when the first plurality of openings (90) and second plurality of openings (120) align, the openings form a plurality of passageways (130) through the outer tubular section (80) and inner tubular section (110). The well screen assembly (70) may therefore, vary the flow of production fluid through it and upwards through the interior of a production tubing (40).
