Hybrid Plug

The Oilenco Hybrid Plug is a downhole well intervention tool that provides secure, high performance well isolation as a barrier, compared to conventional plugging methods. It offers significant operational advantages and improved integrity assurance. The Hybrid Plug combines the simplicity of a regular blanking plug set in a nipple profile, with the integrity assurance of a bridge plug's expanding element. For example, during a tree change out, the production and annulus bores require installation of either a blanking plug or bridge plug for isolation. Blanking plugs are simple, using V-packings to seal, but don't confirm below seal integrity. Bridge plugs have an expanding seal element, allowing pressure tests confirming below seal integrity, but require more complex setting tools and skilled personnel. The Hybrid Plug uses slickline for setting and retrieving in a landing nipple profile within the tubing hanger. A dedicated mechanical setting tool locks it into the profile initially. The innovative dual seal design provides bi-directional sealing and integrity assurance. The simple mechanical design requires no sophisticated setting equipment, and is field redressable.
