ABSTRACT:
A single bore packer is modified by a dual flow seal unit for gas lift completion. This permits the operator to inject lift gas into the upper casing annulus at the well head, bypass the hanger packer and conduct the lift gas into the suspended production tubing below the fluid level. The dual flow seal assembly is sealed internally against the packer mandrel, with the lift gas being conducted through a bypass flow passage between the seal mandrel and the packer mandrel, and being discharged into the lower casing annulus through a discharge port formed through the packer mandrel below the packer seal element package. The hang weight load of the production tubing is decoupled with respect to the packer seal elements by a set of internal ratchet slips which transfers the hang weight load from the packer mandrel onto the anchor slips and well casing at a location below the seal element package.
