Offshore Angola
Provided an effective barrier for an openhole well at water depths of more than than 3,500 ft [1,067 m] for 1,016 days .
Offshore India
Prevented fluid loss and provided suspension for 1,027 days while waiting on the deployment of an interventionless upper completion.
Offshore Malaysia
Protected the drilled wells during the floating production, storage, and offloading development phase in water depths greater than 3,658 ft [1,115 m]. The average suspension time of the 14 wells was more than 690 days, with the longest being 1,600 days.
Location
Malaysia, Asia
Details
Angola, India, and Malaysia
Completion types
Openhole and cased hole
Water depths
Up to 3,658 ft [1,115 m]
Background
Several wells located in Angola, India, and Malaysia experienced typical suspension times of up to 1,600 days—4 years—while upper completions or floating production systems were being installed. FIV-II* formation isolation valves protected
the reservoirs until the operators opened the valves remotely using the Trip Saver* one-trip remote-operating mechanism.
