Initial oil processing takes place on the Oseberg Øst platform itself, followed by additional treatment at the Oseberg Field Center before the hydrocarbons are transported via the Oseberg Transport System to the Sture terminal in Norway.
Technical features
The reservoir is located at a water depth of , positioned between two fault blocks at depths ranging from . The estimated recoverable volumes include of oil, of natural gas, and approximately 100,000 tonnes of natural gas liquids (NGL). Extraction techniques incorporate pressure support through water injection combined with water alternating gas injection methods, achieving a peak daily production rate of .
Updates
Recent enhancements have included the drilling of seven additional wells alongside a NOK1.9 billion capital expenditure by the operating partners aimed at boosting recovery rates from 28% to 35% without relying on support vessels. Upgrades comprised installing a new drilling fluid module equipped with its own generator and transformer, implementing advanced process control systems designed to eliminate drilling waste discharge, adding 20 new living quarters, two lifeboats with a capacity for 62 individuals, and constructing a new loading deck for handling drilling equipment and chemicals.
