With the increase of mature wells, comingled production from multi-zones in long laterals has become more common in recent years. High sand production, wellbore collapse and water invasion from high-pressure aquifers have been observed more frequently. Among these adverse consequences, water invasion is one of the most common issues throughout the production in lateral wells. Various solutions have been introduced to mitigate this, but this paper will focus on an innovative cement retainer which could eliminate the mill out and leave zero debris downhole after the tool functions for zonal water shut off.
