Abstract (en)
[origin: US2022235628A1] A wellbore flow control system includes a production tubular member configured to run into a wellbore formed from a terranean surface and into a subterranean formation; a plurality of autonomous inflow control valves (AICVs) positioned on the production tubular member, each of the plurality of AICVs controllable based at least in part on at least one of a density or a viscosity of a formation fluid; and a plurality of sliding sleeves mounted in the production tubular member, each of the plurality of sliding sleeves mounted near a set of AICVs of the plurality of AICVs, each of the plurality of sliding sleeves controllable based on a wellbore drawdown pressure to fluidly couple or fluidly decouple an inner volume of the production tubular member with the subterranean formation through the particular set of AICVs.
