KINTORE, UK – Sand control specialist Darcy has installed a downhole hydraulic screen in the Statoil-operated Statfjord oil field in the Norwegian North Sea.
The system is designed to provide “pump free” sand control, eliminating the need for specialist pumping crews. Its hydraulic technology is said to be easily activated from surface, eliminating the need for more time-intensive gravel packing.
Statfjord is a mature field undergoing continuous pressure depletion with reduced margins for pumping traditional open-hole gravel packs. Working with Statoil’s completion equipment suppliers, Darcy activated the hydraulic screen using less than one hour of rig time.
A reservoir isolation barrier was closed and tested prior to pulling out of the hole. Completion operations concluded with production flowing. Statoil plans application on further wells in the field.
Steve Bruce, CEO of Darcy, said: “With 70% of mature and deepwater oil and gas wells requiring sand control and experiencing costly challenges, we believe there is a significant market for the hydraulic screen due to its ease of installation and ability to cope with downhole geomechanical and production loading through the life of the well.
“We designed and developed the technology in response to industry concerns about the high failure rate and costs of gravel packing methods. Our hydraulic system offers a more efficient alternative and enables operators to complete wells which would be difficult or impossible using traditional sand control methods.”
