Thru-Tubing Water Shut-off Solution for High Temperature Horizontal Well in South East Asia

Case StudyAn oil and gas operator in South East Asia required a solution to control water-cut production in an offshore well. Multiple zones required effective zonal isolation within the 5-1/2” liner to selectively squeeze water shut-off (WSO) chemicals after passing through a 2.8” ID restriction. With IPI’s solution, Water production and crossflow within the desired formation intervals were successfully shut-off, allowing the operator to improve water-cut production to desired levels. The job was successfully executed in a safe and timely manner without operational issues, which generated substantial savings in operational costs while minimizing offshore platform non-productive time.
