Our external casing packers provide robust, region-specific isolation of multiple loss or water zones in vertical, deviated or horizontal wells. The effective isolation of specific zones at different locations is a critical requirement during the drilling, completion and intervention cycles of well. The inflatable packers deliver a high-pressure seal that eliminates annular flow while maintaining the integrity of the casing. The casing packers are manufactured in standard API casing sizes from 4 1/2 to 13 3/8th inches and customizable sizes are available. For more information about External casing packers, contact us.
