  • Systems and methods for operating downhole inflow control valves
    Patent number: 10597988
    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 (Pf) based on the failure and non-failure times, determining an operational stroking duration based on the probability of failure of the ICVs (Pf), and operating ICVs in accordance with the operational stroking duration determined.
    Type: Grant
    Filed: November 28, 2017
    Date of Patent: March 24, 2020
    Assignee: Saudi Arabian Oil Company
    Inventors: Mohammed Dhafer Al-Ajmi, Nasser Mubarak Al-Hajri
  • Methods and systems for estimating sizes and effects of wellbore obstructions in water injection wells
    Patent number: 10459118
    Abstract: Methods and systems to estimate physical dimensions of actual obstructions identified as being in a wellbore of an injection well are provided. Methods and systems include the determination of a well performance model with a simulated obstruction, using inflow performance and outflow performance relationships.
