Model ESP Electric Submersible Retrievable Packer
The Model ESP Electric Submersible Retrievable Packer is designed to facilitate the use of an Electric Submersible Pump (ESP). The packer can be provided with threaded connections to accept a pack-off power cable feed-through system with cable pigtails, or a drop-through penetrator. Additional optional ports allow venting of annular pressure, fluid injection through the packer, and/or instrument wire port bypass.
The nominal working specifications for the ESP is 3,000 psi (20.7 MPa) differentials pressure at a 300°F (149°C) to 350°F (177°C) service temperature depending on materials.
Key Features & Benefits:
- Fewer parts: The ESP Packer is specifically designed to be run with electric submersible pumps, and is not a modified version of a dual-string production packer. Its simple design and reduced number of parts provide easy retrieval and redress
- Easily set and released: Hydraulically set, straight pull/shear release
- Short, compact design: Its length (less than 4 feet) makes it easier to run and handle.
- Separate gas venting string: No venting through primary or secondary strings
- Designed to fit special needs: Optional ports through packer
- No relative movement between tubing and cable: Eliminates cable strain
- Mechanically locked in set position: A body lock ring holds the packer in the set position
- Double-grip, caged slips: Eliminates the need for hydraulic hold-downs. Top and bottom cones drive slips into the casing wall and hold loads from either direction
- Holds pressure from above and below: Packing element packs-off tighter and slips grip tighter as pressure increases from either direction
- Threaded connections can be adapted to most other feed-through systems
