In this work, a computational study of a heavy oil (228cP) reservoir in the Santos Basin with 115 m thickness is modeled using Rocx coupled with OLGA. The horizontal well is simulated with both AICV (300 days) completion and openhole with gravel pack completion (200 days). The well has a length of 650m, diameter of 0.24m and is divided into 10 sections. The differential pressure is 20bar. The reservoir is considered heterogeneous with permeability ranging from 5D to 50D. Using AICV completion the valves closes first in the highest permeability zone and then following the heel-to-toe effect.
The results confirm that the water breakthrough to the well can be avoided by using AICV completion. The technology will contribute to extend the lifetime of a well and result in reduced costs regarding oil-water separation.
