Description
Description TypeTextDate updatedDevelopmentOseberg Øst is a field in the northern part of the North Sea, 15 kilometres east of the Oseberg field. The water depth is 160 metres. Oseberg Øst was discovered in 1981, and the plan for development and operation (PDO) was approved in 1996. The field has been developed with an integrated fixed facility with accommodation, drilling equipment and first-stage separation of oil, water, and gas. The production started in 1999. A PDO exemption for the Beta East segment was granted in 2004.13.12.2023ReservoirOseberg Øst produces oil from Middle Jurassic sandstone in the Brent Group. The field consists of two structures which are separated by a sealing fault. The structures contain several oil-bearing layers with variable reservoir characteristics. The reservoirs are at depths of 2700-3100 metres.09.12.2023Recovery strategyThe field is produced by partial pressure support from both water injection and gas injection. Water for injection is produced from the Utsira Formation.28.02.2023TransportThe oil is sent by pipeline to the Oseberg Field Centre for further processing and transport through the Oseberg Transport System (OTS) to the Sture terminal. The gas is mainly used for injection, gas lift and fuel.28.02.2023StatusOseberg Øst is at the tail end of its production phase and the main challenge is to maximise the oil recovery within the field lifetime. To increase production, the focus is on drainage strategy, including optimisation of injection and well interventions. Maximising the gas production rate is also of importance, as the produced gas is used as fuel supply for the platform power generator.09.12.2023 -
