Equinor has signed three-year contracts with Tendeka and Baker Hughes Norge for providing sand screen services worth £92.5 million.
Sand screen technology is based on a metal filter preventing sand from entering and damaging the wells.
This key technology is applied to secure production and extend the life of wells.
Peggy Krantz-Underland, Equinor’s chief procurement officer, said: “These suppliers have been our service providers over time.
“They will be central in our effort of making wells more profitable.
“We are looking forward to continuing our good cooperation for many years ahead.”
Tendeka has been awarded a contract for providing sand screen services to the Troll field, which has the most widespread use of such screens.
Furthermore, they have already signed contracts for similar services to the two Cat J rigs that are drilling for the Gullfaks and Oseberg fields.
Baker Hughes Norge has been awarded a contract for providing sand screen services to the other Equinor-operated fields on the Norwegian continental shelf.
Both suppliers will also supply valves preventing undesirable fluids from entering the production stream, in addition to preventing sand from entering the wells.
