Abstract
A frac and gravel packing system including a tubular having a longitudinal axis, a wall defining an interior flowbore, a radial frac port and a radial production port extending through the wall in a first zone of an annular region surrounding the tubular; a screen surrounding the production port, the frac port not covered by the screen; a sleeve system including a sleeve longitudinally shiftable with respect to the longitudinal axis of the tubular, the sleeve configured to cover the frac port in a first position of the sleeve and uncover the frac port in a second position of the sleeve; and, a return path arranged to permit return fluid from a fracturing operation to exit the first zone of the annular region, wherein the return fluid passes through the screen prior to accessing the return path.
