Encapsulated ESPs (or pods) are commonly used in ESP well
completions as an alternative to using ESP packers.
The ESP is installed inside a sealed unit with a packer style cable connector at the Pod hanger. With an ESP pod completion, the tailpipe below the pod has a seal assembly that engages the seal bore packer.
This then isolates the production casing above the packer from the produced well fluids, protecting your casing from potential corrosion and erosion of the production casing at the pump intake.
Workover can be achieved with an isolation valve to prevent
damage to the formation with kill fluids.
Advantages
- Isolates the production casing from produced well fluids
- ESP packer is replaced with a seal bore packer
- Workovers can be done without killing the well and damaging the well perforations with kill fluid
- Used in ESP Drill Stem Tests (DST) where annulus pressure is applied to actuate DTS tools
Disadvantages
- No access to the well reservoir
