Detailed Description

The Ballycatter Model WC-ESP Packer – Cut to Release Version is a high-performance hydraulic-set production packer designed for completions requiring an electric submersible pump (ESP) below the packer. This single-mandrel, dual-bore packer features a pass-through section, enabling an electric cable to run through the packer, delivering power to the ESP for efficient fluid production.

The packer is hydraulically set by applying tubing pressure against a plugging device, and once engaged, it is mechanically locked in place with an internal slip mechanism. The bi-directional barrel slips secure the packer against well pressures from above and below, ensuring reliable performance in demanding well conditions. Additionally, it is equipped with NPT chemical injection ports and a vent valve port, providing operational flexibility for chemical treatment and pressure regulation.

One of the standout features of the WC-ESP Packer is its Cut to Release function, which enhances retrieval efficiency and simplifies intervention operations. Unlike conventional packers that rely solely on straight pull release, this cut-to-release mechanism ensures controlled retrieval even in wells where high overpull may be a concern. This design reduces the risk of damage to the tubing string and downhole equipment, improving operational safety and reducing intervention costs. The field-adjustable straight pull release allows for on-site modifications, ensuring adaptability across different well environments. The single-piece mandrel construction and Acner Array Packing Element further enhance its durability, making it suitable for hostile downhole conditions while maintaining a reliable seal.

The WC-ESP Packer is furnished with a universal 1.900” API NU connection for penetrators, ensuring compatibility with all major cable pack-off or feed-thru devices. Its bi-directional barrel-slip design provides high loading capacity, ensuring a uniform transfer of load while maintaining structural integrity. With single-trip capability, operators can efficiently set the packer while minimizing rig time and operational complexity.

Whether deployed in standard or high-pressure, high-temperature wells, the Ballycatter WC-ESP Packer – Cut to Release Version offers unparalleled reliability, ease of retrieval, and superior performance for ESP completions.
