Our activities in the UK

How to find us in the UK

A reliable partner for Britain

Statoil has a broad range of activities in the UK, including offshore wind, upstream operations, natural gas trading and crude oil sales.

On the UK continental shelf we operate the Mariner, Bressay AND UTGARD FIELDS, as well as being partners in the Jupiter and Alba fields.

Statoil also holds interests in more than 20 exploration licenses, most of them as operator. We are increasing our investment on the UK continental shelf through the development of the Mariner field, an ambitious 30-year project which represents one of the largest capital expenditure commitments on the UK continental shelf for over a decade—a gross investment of more than GBP 4.5 billion.

The UK is also home to Statoil’s growing renewables portfolio.

We are applying our expertise in offshore operations to developing several offshore wind technologies and projects. Our Hywind Scotland Pilot floating wind Park represents the next phase of offshore wind power generation. 

The Sheringham Shoal and Dudgeon offshore wind farms will supply electricity to 630,000 UK homes. We are also partners in the Dogger Bank offshore wind project, which has the potential to provide around 10% of total UK electricity requirements.

Natural gas is a key part of Statoil’s energy partnership with the UK.

4.1 million UK homes are fuelled by Statoil gas and we are committed to increasing that figure. Through the Langeled, Vesterled and Tampen Link pipelines from the Norwegian continental shelf, Statoil has capacity to supply around 25% of peak UK demand. In 2015 we cemented our position as a long-term reliable and competitive supplier with agreements to deliver 73 billion cubic metres (bcm) over 10 years to Centrica and 2.5 bcm annually to SSE, the UK’s two largest energy suppliers. By doing so Statoil aims to help the UK meet its increasing demand and secure sustainable energy supplies for the future.

Mariner—a new era for Statoil on the UK continental shelf

In late 2018 a thirty-year adventure will begin 250 kilometres off Scotland’s north-east coast. That’s when the first oil tanker will leave the Mariner field, bound for the world’s energy markets. It’s been a long journey. Mariner is a sleeping giant, discovered more than thirty years ago. 


But because of the oil’s extremely high viscosity, previous operators were not able to extract it. In 2007, we acquired the operatorship, and with the experience gained from working with other heavy oil fields, we managed to solve the challenges. The Mariner project will be one of Statoil’s most innovative developments ever.

Discovered in 1981 on the East Shetland Platform, approximately 150 kilometres east of the Shetland Islands, the Mariner field is a daunting prospect for oil and gas producers. Mariner is a heavy oil field characterised by dense, viscous oil.

In December 2012, Statoil and its partners decided to take on the challenge and made the investment decision for the Mariner project, which entails a gross investment of more than GBP 4.5 billion. This was the largest capital commitment to the UK Continental Shelf (UKCS) in more than a decade.

The concept chosen includes a production, drilling and quarters (PDQ) platform based on a steel jacket, Mariner A, with a floating storage unit (FSU), Mariner B. Drilling will be carried out from the Mariner A drilling rig, with a jack-up rig assisting for the first 4 years.


The Mariner oil field consists of two shallow reservoir sections: the deeper, Maureen formation at 1492 meters and the shallower Heimdal reservoir at 1227 meters. The oil is heavy with API gravities of 14.2 and 12.1 and viscosities at reservoir conditions of 67 cP and 508 cP, respectively for Maureen and Heimdal.  

The development of the Mariner field will contribute more than 250 mmbbls reserves with average plateau production of around 55,000 barrels per day. The field will provide a long term cash-flow over 30 years.  Production is expected to commence in 2018.

 

The steel jacket was installed in the field during the summer of 2015. The topsides modules are being constructed by Daewoo Shipbuilding & Marine Engineering Co., Ltd. (DSME). 

 

Heavy oil projects have required the development of pioneering technology. Since its discovery in 1981, the Mariner field has been subject to a number of development studies by different operators. Statoil was the first company to put forward a development concept that will fully address the complexities of this field.  

We are the operator of the Mariner field with 65.11% equity. Co-venturers are J.X. Nippon (20%), Siccar Point Energy (8.89%) and Dyas (6%).  

The Mariner field will in the initial years employ 700 people, offshore and onshore, contractors included. It will also support a significant number of jobs in the UK supply chain.

Statoil has awarded the contract for drilling services on the Mariner platform to UK-based Odfjell Drilling. Noble Corporation is awarded the contract for the additional jack-up rig that will assist the PDQ in the initial years. This rig is currently in operation in the Mariner field.

The Mariner maintenance and modification services contract has been awarded to Aker Solutions UK. The offshore services contract has been awarded to Stork Technical Services Limited, also based in the UK. The helicopter transportation contract for the Mariner field has been awarded to CHC Helicopter in the UK.

A leading player in offshore wind

Statoil is an important player in the UK’s burgeoning offshore wind sector

The Sheringham Shoal field, located just off the Norfolk coast, started production in 2012. Located nearby, the Dudgeon offshore wind farm, also developed in partnership with Norwegian company Statkraft, will come online in 2017. Together, Sheringham and Dudgeon will supply electricity to 630,000 UK homes.

Furthermore, we are partners in the Dogger Bank offshore wind project and are pioneering floating wind technology through the Hywind Scotland Pilot Park off the coast of Peterhead in Aberdeenshire. Floating wind potentially represents a new and significant renewable energy source that will complement an existing and expanding array of alternative energy projects. Our Hywind project is expected to demonstrate the feasibility of multiple floating wind turbines in a region that has optimal wind conditions.

Statoil’s offshore wind projects are a key component in our commitment to reducing carbon emissions. Every megawatt hour produced from wind theoretically displaces approximately one tonne of carbon dioxide from coal power (and about half a tonne compared to gas-fired power).
