DEVELOPMENT

Jotun is a field in the central part of the North Sea, 25 kilometres north of the Balder field. The water depth is 125 metres. Jotun was discovered in 1994, and the plan for development and operation (PDO) was approved in 1997. The field was developed with Jotun A, a combined production, storage and offloading vessel (FPSO), and Jotun B, a wellhead facility. Jotun is integrated with the Balder field. Production started in 1999.

RESERVOIR

Jotun produced oil from sandstone of Paleocene age in the Heimdal Formation. The reservoir lies at 2,000 metres depth in a marine fan system and comprises three structures.

RECOVERY

The field was produced by pressure support from the aquifer and with gas lift. Produced water was injected into the Utsira Formation.

TRANSPORT

The Jotun FPSO is an integrated part of the Balder and Ringhorne facilities and is still in operation. It receives oil and gas from Ringhorne, and excess gas from Balder. Jotun processes and exports rich gas via Statpipe to Kårstø. The oil is exported via the production vessel at Jotun to tankers on the field.

STATUS

Production from the field ceased in 2016. Jotun B was removed in 2020 and the Jotun FPSO will be upgraded and relocated to continue operation for the Balder and Ringhorne Øst fields from 2023.

Vår Energi awards Jotun A FPSO life extension contract to Worley

Rosenberg Worley, Worley’s Norwegian subsidiary, has been selected by Vår Energi AS to provide life extension services for their Jotun A FPSO (floating production storage offloading) vessel.

Rosenberg will provide management, engineering, procurement, refurbishment, construction and commissioning services for the FPSO. It will involve decommissioning, refurbishment in the yard in Stavanger and offshore deployment. The project will enable the continued production of oil and gas from the Balder field until 2045.

The project will utilize both Rosenberg’s Norwegian facilities and expertise, and the UK North Sea capabilities of Worley’s Aberdeen office. The contract will provide local job opportunities in Stavanger. Extending the life of the Jotun A FPSO towards 2045 in the Balder Future Project supports Vår Energi’s future growth plans and Norway’s first offshore license, PL 001, extending its life span to 80 years.

“We are delighted to support Vår Energi’s future growth plan by extending the life of the Balder field and servicing its assets in the North Sea,” said Andrew Wood, Chief Executive Officer of Worley.

BALDER AREA LIFETIME EXTENSION TO 2045

Vår Energi AS and license partner Mime Petroleum AS plan to extend the Balder and Ringhorne production lifetime to 2045. The Balder Future project – a revised Plan for Development and Operations (PDO) for Balder and Ringhorne, was submitted to the Norwegian Ministry of Petroleum and Energy today.

The Balder Future project involves drilling thirteen new production wells and one new water injection well on the Balder field the North Sea. The aim is to recover 136 million barrels of oil equivalent (Mboe).

The project also includes extending the lifetime of the floating production storage and offloading vessel Jotun A FPSO.

The PDO document was formally handed over by Vår Energi AS CEO Kristin F. Kragseth to the Minister of Petroleum and Energy, Kjell-Børge Freiberg, during a short ceremony at the MPE offices in Oslo today.

Increased recovery

The Balder field is in production license PL 001 – the very first license on the Norwegian Continental Shelf (NCS). On current production estimates, the project will give the license a total lifespan of over 80 years.

− We are proud to carry the PL 001 legacy forward, and by utilizing existing infrastructure, we contribute to good resource management on the NCS. For Vår Energi this is a major step, and we are proud to be the operator of the Balder Future project, which will be one of the largest projects on the NCS the coming years, says Kragseth.

Balder Future represents a NOK 19.6 billion (USD 2.2 bn) investment, and is expected to create almost 30 000 man-years of work through the development project and operations to 2045.

In addition to the new production wells, the project will enable the drilling of extra subsea infill wells, and new wells from the neighboring Ringhorne platform. Vår Energi also has plans to execute further exploration drilling in the area, which if successful will potentially add even more reserves. All these activities will take place while ordinary production continues at the Balder and Ringhorne fields.

Local suppliers

Earlier this year, Vår Energi AS awarded an EPCI (Engineering, Procurement, Construction and Installation) contract to Rosenberg Worley AS in Stavanger, Norway for the lifetime extension of the Jotun A FPSO. Under another contract, Baker Hughes and Ocean Installer will engineer, procure, construct and install new subsea production systems, umbilicals, risers and flowlines for the Jotun A FPSO.

− We want to generate opportunities wherever we have our business, and do what we can to create employment and industry ripple effects. I’m happy to see that the main contracts have been awarded locally – which will benefit the supplier industry in the Stavanger region, says Balder Future Project Manager, Lars Håvardsholm.

The Jotun A FPSO will be brought to shore mid 2020 for its upgrade and life extension. During the summer of 2022 the vessel will be reinstalled in the area between the Balder and Ringhorne fields.

Growth plans

Vår Energi has reserves and resources of more than 1,900 million barrels of oil equivalent. Daily production is expected to reach 350,000 barrels of oil equivalent by 2023, following NOK 65 billion investments in development projects on the NCS. Balder Future is a key project in this growth plan.
