Hanz Oil and Gas Field Profile
Location and Geology
- The Hanz oil and gas field is located in the Norwegian North Sea, specifically in licence 028 B on the Utsira High, approximately 175 km west of Karmøy.
- The field is situated at a water depth of 115 meters.
- The hydrocarbons at Hanz are found in sands belonging to the Middle Jurassic and Paleocene age.
Discovery and Development
- The Hanz field was discovered in 1997 by Esso.
- The development of the Hanz field was sanctioned in December 2021 by Aker BP and its partners Equinor and Sval Energy (previously Spirit Energy).
Partners and Ownership
- Aker BP is the operator of the Hanz field with a 35% stake.
- Equinor holds a 50% stake.
- Sval Energy holds a 15% stake.
Development Concept
- The Hanz field is developed as a subsea tieback to the Ivar Aasen platform, which is located about 15 kilometers to the south.
- This development involves the reuse of subsea production systems (SPS) from the Jette field, marking the first instance of production equipment being repurposed in a new field development on the Norwegian Continental Shelf (NCS).
Innovative Solutions
- The project incorporates innovative solutions such as the use of a cross-flow well for water injection. This approach reduces power consumption, chemical usage, and the amount of seabed equipment required.
Reserves and Production
- The total reserves of the Hanz field are estimated to be around 20 million barrels of oil equivalent (mmboe).
- Production from the Hanz field began in the first half of 2024.
Investments and Costs
- The initial investment decision was based on an estimated NOK 3.3 billion ($364 million), but total investments are now estimated to be around NOK 5 billion ($454 million).
Environmental and Cost Efficiency
- The development solution adopted for Hanz is more cost-efficient and has a smaller environmental footprint compared to the original plan. This aligns with Aker BP’s goals of producing with low costs and low emissions.
Infrastructure and Export
- Oil from the Hanz field is exported to the Sture terminal via the Grane Oil Pipeline, while gas and natural gas liquids (NGLs) are exported to the UK terminal at St. Fergus via the SAGE transport system.
Power Supply
- The Ivar Aasen platform, which hosts the Hanz field production, receives power from the Edvard Grieg platform. Since 2022, the field has also received power from shore via the Johan Sverdrup field, significantly reducing CO2 emissions.
Operational Significance
- The production start from Hanz helps maintain good production levels from the Ivar Aasen platform, which is crucial for the overall development of the Ivar Aasen area.
