Norsk Hydro Produksjon AS has been granted consent to carry out major modifications to the Oseberg Øst installation. Today the installation does not have equipment to treat/circulate drilling fluid and cement, and therefore depends on support vessels (TSV) in order to carry out drilling operations. The modifications are necessary to implement future drilling operations without TSV.

Oseberg Øst is located approximately 100 km northwest of Bergen. The installation was originally built as a process platform and living quarters equipped with an integrated drilling rig. In accordance with the plan for development and operations (PDO), drilling operations have been supported by the mobile rig Borgila Dolphin.

Norsk Hydro is of the opinion that the planned drilling of seven new wells could increase producible reserves by approximately 40 million barrels of oil. The wells will be drilled without support vessels.
