ABSTRACT:
A production packer comprising a packer body, a flat plate, a sealing element, production tubing, water overflow tubing, gas vent tubing, pump cable pack-off tubing, and an optional pressure transducer port. The flat plate is welded onto the top of the packer body. The sealing element is bonded to the outside of the packer body. In the preferred embodiment, the packer body is a steel pipe, and the flat plate is made of steel. The packer is placed inside a production casing, and the diameter of the sealing element is greater than the diameter of the production casing. The sealing element is made out of a material that is durable enough to withstand the pressures associated with a production packer, flexible enough to fit inside the production casing, and elastic enough to create a seal between the packer body and the production casing.
