Abstract

Provided are systems and method for operating and maintaining downhole inflow control valves (ICVs) of hydrocarbon wells, including monitoring the operations of ICVs to identify failure and non-failure times of defective and non-defective ICVs, respectively, determining a probability of failure of the ICVs (P) based on the failure and non-failure times, determining an operational stroking duration based on the probability of failure of the ICVs (P), and operating ICVs in accordance with the operational stroking duration determined.
