Reduced water production and increased oil production in a matured heavy oil field
As the field has a faulted reservoir with an active aquifer, many wells were producing with very high water cut (>95%). Stand-alone screens (SAS) along with zonal isolations were not able to restrict the higher water production.
The AICV® is based on Hagen-Poiseuille’s equation & Bernoulli’s principle and operates autonomously such that it opens for high viscous fluid such as oil and close for low viscosity fluid such as water and gas. Due to this unique feature of the AICV®, the operator decided to complete several dozens of wells with AICV® joints and annular isolation packers for compartmentalisation.
