Challenge: In a remote, harsh environment, bring 30 new wells onto production in such a way that improves recovery and reduces intervention costs

Solution: Use FIV formation isolation valve to isolate and protect formations during perforating and completion operations

Results: Realized up to 20% increase in hydrocarbon recovery from the 30 wells. Saved an estimated USD 15 million in coiled tubing intervention costs. Helped save USD 23.5 million in rig time and hardware costs

Isolation Valve Minimizes Formation Damage When Perforating

FIV Formation Isolation Valves reduce well intervention costs west of Shetlands

Complete wells without killing the producing formations

An operator approached Schlumberger with a project in a field west of the Shetland Islands: batch drill and complete 30 wells without damaging the producing formations. The challenges included perforating underbalanced and minimizing formation damage by keeping hydrocarbons on the formation during well operations—all while reducing intervention costs.

Provide a barrier during workover operations

Schlumberger recommended using FIV tools and completion equipment to protect the formation during perforating and completion operations. The first tool installed in the field has operated trouble-free for more than 5 years, providing a barrier during workover operations.

The FIV tool acts as a downhole lubricator valve, allowing long strings of perforating guns to be run into and retrieved from the well while isolating the zone below.

Increased hydrocarbon recovery

The operator credits protecting the formation during completions and workovers for the 10% to 20% increase in hydrocarbon recovery from these wells. FIV valves have saved an estimated USD 15 million in coiled tubing intervention costs simply by providing a barrier for setting production packers. They have also helped save USD 23.5 million in rig time and hardware costs.
