Patent abstract
A wellbore tubular has openings in its wall. An outer sleeve has ridges on which openings are located so that they communicate with the tubular openings. The tubular can be expanded to plant the ridges against the formation while any space between the ridges and the borehole wall can be used for pumping cement without fouling the aligned openings between the tubular and the sleeve. Optionally the sleeve can swell with or without tubular expansion. The openings can be initially sealed for delivery to the desired location and then opened using well or added fluids or well conditions.
