The 200th installation was recorded in the North Sea, where 11 joints of 4-inch ESS were successfully expanded in a 5-7/8 inch open hole to a TD of 9,955 feet. Early indications are that production rates have considerably exceeded expectations, with reservoir completion showing zero skin. This installation is part of a wider gas field development, where ESS has already been successfully installed.
Nicholas Gee, Vice President for Expandable Sand Screen said, "Weatherford is the global leader in the commercialization of Expandable Sand Screen technology, with over 200 successful installations worldwide to date in a wide range of applications. This amounts to over 25 miles, including the world's longest run of ESS at 7,030 ft."
"Worldwide, more and more customers are recognizing the productivity improvements and cost reductions that ESS can offer, compared with traditional sand control methods. Typically well costs have been cut by over 20%, and productivity increased by up to 70%. A key benefit of Weatherford's Expandable Sand Screens is the ability for them to be expanded compliantly, eliminating the annulus and supporting the wellbore," Gee said.
