The WTAR permanent seal-bore packer is a high-performance production packer designed for single or multiple-zone completion in high differential pressure environments. It can be set using wireline, electric line, or a hydraulic tool installed on the tubing or drilling string. The packer provides the largest possible bore through the combined packer and seal assembly, ensuring maximum flow capacity. An optional receiving head arrangement is available upon request. The seal nipple is designed with either a left-hand thread latch or a locating shoulder for enhanced operational flexibility. Additionally, a specified packer bottom can be configured to connect with a mill-out extension, seal bore extension, or other standard packer accessories. The WTAR packer can be removed by milling or drilling, making it suitable for long-term completion solutions.
