Abstract
A sand control screen assembly (40) is operably positionable within a wellbore (50). The sand control screen assembly (40) includes a base pipe (42) having a plurality of openings (46) in a sidewall portion thereof and an internal flow path (44). A plurality of radially extendable filter members (52) are each operably associated with at least one of the openings (46) of the base pipe (42). The radially extendable filter members (52) have a circumferential dimension that is less than a longitudinal dimension thereof. The radially extendable filter members (52) have a radially retracted running configuration and a radially extended operating configuration, in which, the radially extendable filter members (52) preferably contact the wellbore (50).
