Abstract
An apparatus (60) and method for gravel packing an interval of a wellbore is disclosed. The apparatus (60) comprises a sand control screen (78) that is positioned within the wellbore and a tube and manifold system (62) positioned between the sand control screen (78) and the wellbore. The tube and manifold system (62) delivers a fluid slurry to a plurality of levels within the interval when the apparatus (60) is in an operable position. The tubes (64, 70, 76) of the tube and manifold system (62) have first and second ends which are open such that the fluid slurry may enter one end, travel through the entire length of the tube (64, 70, 76) and exit the other end. The manifolds (66, 72) of the tube and manifold system (62) each have at least one exit port (68, 74) for the discharge of the fluid slurry from the tube and manifold system (62).
