Patent attributes
A first interval inflow control device and a second interval inflow control device are positioned on a production tubing string proximate to a first subterranean interval and a second subterranean interval, respectively. The inflow control devices each include a central bore, a sand screen surrounding an inner tube, a plurality of ports connect the annular space between an inner surface of the sand screen and an outer surface of the inner tube, and a sliding sleeve configured to translate between an open position and closed position. A first shifting tool is configured to engage with and axially translate the sliding sleeve of the first interval inflow control device and a second shifting tool is configured to engage with and axially translate the sliding sleeve of the second interval inflow control device. The second shifting tool has an outer diameter less than the bore of the first interval inflow control device.
