WA Permanent Seal Bore Packer
The Model “WA” permanent seal-bore packer is a high- performance production packer designed for single or multiple- zone completion with high differential pressure. It can be set on wireline, electric line or with a hydraulic tool installed on the tubing or drilling string. The packer features the largest possible bore through combined packer and seal assembly. Optional receiving head arrangement can be provided on request. And the seal nipple is available with either left-hand thread latch or locating shoulder. Also, a specified packer bottom can be provided to connect a mill out extension, seal bore extension or other standard packer accessories. This packer can be removed by milling or drilling. The WA packer is designed with a one-piece mandrel to avoid potential leakage path. The tripled multidurometer element package and two full-circle opposed slips design make it is ideally suited for wells where extremely high pressure or temperature encountered. The low profile design makes it easier to run into a high deviated well.
