TRIDENT was deployed from a deepwater drill ship in West Africa for a slot recovery operation in 3,700ft of water. CNR required a Bridge Plug to be set at 6,660ft, well fluid displaced, then 13 3/8” casing to be cut below the shoe at 6,614ft and recovered from 3,748ft to allow for an open-hole Sidetrack.

Ardyne’s TRIDENT system provided the capability to complete the operation in a single trip. A third party Bridge Plug was run below the TRIDENT and set mechanically prior to pulling back to cut depth and setting the TRIDENT Anchor. The Anchor removes the requirement for a Marine Swivel in deepwater applications, allowing the string to be spaced out anywhere. The cutter was then activated before verifying the casing was free from bottom. After relocating the TRIDENT Anchor below the casing hanger, the casing was recovered to surface.
