In long horizontal wells, production rate is typically higher at the heel than at the toe. The resulting imbalanced<br>production profile may cause early water or gas breakthrough into the wellbore. Once coning occurs, well production may be<br>severely decreased due to limited flow contribution from the toe. To eliminate this imbalance, inflow control devices (ICDs)<br>are placed in each screen joint to balance the production influx profile across the entire lateral length and compensate for<br>permeability variation. Passive ICDs should be designed to control the influx without the need for intervention.
