|
Status
|
Production from Alve is constrained by the commercial agreement with the Norne licence and the gas handling capacity on the Norne FPSO. Excess capacity on the FPSO in recent years has made it possible to process larger volumes of gas from Alve. The long-term activity on the field is to optimise production. An exemption from a PDO was granted for the development of the discovery 6507/3-8 Andvare in 2023. Andvare will be drilled and produced from an available well slot on Norne.

EKOFISK
|
Development

Ekofisk is a field in the southern part of the Norwegian sector in the North Sea. The water depth is 70 metres. Ekofisk was discovered in 1969, and the initial plan for development and operation (PDO) was approved in 1972. Test production was initiated in 1971 and ordinary production started in 1972. The production was initially routed to tankships until a concrete storage tank was installed in 1973. Since then, the field has been further developed with many facilities, including facilities for associated fields and export pipelines. Several of the initial facilities have already been removed or are awaiting decommissioning. The initial field development started with three production platforms: Ekofisk A, Ekofisk B and Ekofisk C. Wellhead platform Ekofisk X and process platform Ekofisk J were installed in 1996 and 1998, respectively, as part of the Ekofisk II project. In 2005, wellhead platform Ekofisk M was installed as part of the Ekofisk Growth Project. A plan for water injection at Ekofisk was approved in 1983. Ekofisk K, which is the main injection facility, started water injection in 1987 and is still in operation. There had also been water injection at Ekofisk W from 1989 until 2009, when Ekofisk W was shut down and replaced by a subsea template, Ekofisk VA. A PDO for the development of Ekofisk South was approved in 2011. The project included two new installations in the southern part of the field: production platform Ekofisk Z and a subsea template for water injection, Ekofisk VB. Injection from Ekofisk VB and production from Ekofisk Z started in 2013. The accommodation facilities Ekofisk H and Ekofisk Q were replaced by Ekofisk L in 2014. An amended PDO for an additional water injection template, Ekofisk VC, was approved in 2017.

EKOFISK
|
Recovery strategy
|
Ekofisk was originally produced by pressure depletion and had an expected recovery factor of 17 per cent. Since then, comprehensive water injection has contributed to a substantial increase in oil recovery. Large-scale water injection started in 1987, and in subsequent years, the area for water injection has been extended in several phases. Experience has proven that water displaces the oil much more effectively than anticipated, and the expected final recovery factor for Ekofisk is now estimated to be over 50 per cent. In addition to the water injection, compaction of the soft chalk provides extra force to drainage of the field. The reservoir compaction has resulted in about 10 metres subsidence of the seabed, especially in the central part of the field. It is expected that the subsidence will continue, but at a much lower rate.

EKOFISK
|
Status
|
The production from Ekofisk is maintained at a high level through continuous water injection, drilling of production and injection wells, and well interventions. Water injection is extended in the southern part of the field. Key challenges are identifying the remaining oil pockets in a mature, waterflooded reservoir, as well as handling the increasing volumes of produced water. Infill drilling on Ekofisk is expected to continue throughout the lifetime of the field. Various drilling methods are being studied to reduce drilling costs, for example coiled tubing drilling. In 2022, the production licence 018, which includes the Ekofisk field, was extended until 2048.

Eldfisk was originally produced by pressure depletion. In 1999, water injection was implemented through horizontal injection wells. Pressure depletion and the water weakening effect have caused reservoir compaction, which in turn has resulted in several metres of seabed subsidence. The Eldfisk II project extends waterflooding on the field.

The initial development consisted of three facilities: Eldfisk B (a combined drilling, wellhead and process facility), and Eldfisk A and Eldfisk FTP (wellhead and process facilities). The production started in 1979. A PDO for water injection was approved in 1997, and the injection facility Eldfisk E was installed in 1999. This facility also provides some the water to Ekofisk K for injection on the Ekofisk field. A PDO for Eldfisk II was approved in 2011, and included a new integrated facility, Eldfisk S, connected by bridge to Eldfisk E. The production from Eldfisk S started in 2015. This facility replaces several functions of Eldfisk A and Eldfisk FTP. Eldfisk A is converted into a wellhead platform and Eldfisk FTP is used as bridge-support facility. The Embla field, located south of Eldfisk, is tied to Eldfisk S. An amended PDO for the subsea development of the northern part of the field, Eldfisk North, was approved in 2022.

GRANE
|
Recovery strategy
|
The field is produced by gas injection at the top of the structure, and horizontal production wells at the bottom of the oil zone. In 2010, Grane terminated gas import from the Heimdal gas centre, and only produced gas was reinjected into the reservoir. Gas import started up again in 2014. Grane has limited water injection. Oil recovery is maintained by gas injection and drilling of new wells, including sidetracks from existing producers.

Gullfaks is a field in the Tampen area in the northern part of the North Sea. The water depth is 130-220 metres. Gullfaks was discovered in 1978, and the plan for development and operation (PDO) for Gullfaks Phase I was approved in 1981. A PDO for Gullfaks Phase II was approved in 1985. The production started in 1986. The field has been developed with three integrated processing, drilling and accommodation facilities with concrete bases (Gullfaks A, B and C). Gullfaks B has a simplified processing plant with first stage separation. The Gullfaks facilities are involved in production and transport from Tordis, Vigdis, Snorre, Visund, Visund Sør and Brime. A PDO for Gullfaks Vest was approved in 1993, and for recovery from the Lunde Formation in 1995. An amended PDO for the Gullfaks field, covering prospects and small discoveries, which could be drilled and produced from existing facilities, was approved in 2005. Amendments to the Gullfaks PDO, covering Phase I and Phase II production from the Shetland/Lista deposit, were approved in 2015 and 2019, respectively. In 2020, an amended PDO for the development of the Hywind Tampen wind farm was approved. The wind farm consists of 11 floating turbines that started supplying electricity to the Gullfaks and Snorre platforms in 2022/2023. These fields are the first in the world receiving power from a floating wind farm.

Reservoir
|
Gullfaks produces oil from Middle Jurassic sandstone in the Brent Group, and from Lower Jurassic and Upper Triassic sandstone in the Statfjord Group and Cook and Lunde Formations. Recoverable oil is also present in fractured carbonate and shale in the overlying Shetland Group and Lista Formation. The reservoirs are at depths of 1700-2000 metres in rotated fault blocks in the west and a structural horst (raised fault block) in the east, with a highly faulted area in between. Reservoir quality is generally good to very good in the Jurassic reservoirs within each fault compartment, but poor reservoir communication is a challenge for pressure maintenance.

Gullfaks Sør is a field in the northern part of the North Sea, just south of the Gullfaks field. The water depth is 130-220 metres. Gullfaks Sør was discovered in 1978, but comprises several discoveries made in later years. The Gullfaks Sør deposits have been developed with a total of 13 subsea templates tied-back to the Gullfaks A and Gullfaks C facilities. The initial plan for development and operation (PDO) for Gullfaks Sør Phase I was approved in 1996 and included production of oil and condensate from the Gullfaks Sør, Rimfaks and Gullveig deposits. The production started in 1998. The PDO for Phase II was approved in 1998 and included production of gas from the Brent Group in the Gullfaks Sør deposit. In 2004, the Gulltopp discovery was included in Gullfaks Sør. Gulltopp is produced through an extended reach production well from the Gullfaks A facility. A PDO for the Skinfaks discovery and Rimfaks IOR was approved in 2005. An amended PDO for the redevelopment of Gullfaks Sør Statfjord Formation with two new subsea templates was approved in 2012. A PDO for Gullfaks Rimfaksdalen, which includes the Rutil and Opal deposits, was approved in 2015. It consists of a new subsea template and four production wells. Since 2017, gas production is increased by two subsea wet gas compressors, tied-back to the Gullfaks C platform. A PDO exemption for some prospects and small discoveries, which can be drilled and produced from existing Gullfaks Sør facilities, was granted in 2018.

NJORD
|
Recovery strategy
|
Initial production strategy was gas injection for pressure support in parts of the reservoir and pressure depletion in the rest of the reservoir. After gas export started in 2007, only minor volumes of gas have been injected. Due to the complex reservoir with many faults, the field has a relatively low recovery factor.

RINGHORNE ØST
|
Status
|
The field is in its tail production phase. A new infill well is planned to be drilled. Ringhorne Øst will also benefit from an amended PDO for Balder and Ringhorne that was approved in 2020. Field lifetime will be prolonged, and production can benefit from increased capacity in the area. The Jotun FPSO is currently at a shipyard undergoing maintenance and upgrades. It is scheduled to be back on the field in 2024. Until then, excess gas is being injected in the Balder and Ringhorne Øst fields.

SIGYN
|
Status
|
The field is in its late tail production phase. An infill well was put on production on Sigyn East in 2022 and the existing producer was converted to a gas injector. Production is limited by well performance and available flowlines. Currently, there is only production from Sigyn East. Production from Sigyn West is limited because the available flowlines are used to inject gas and produce oil from Sigyn East.

Statfjord is a field in the Tampen area in the northern part of the North Sea, on the border between the Norwegian and UK sectors. The Norwegian share of the field is 85.47 per cent. The water depth is 150 metres. Statfjord was discovered in 1974, and the plan for development and operation (PDO) was approved in 1976. The field has been developed with three fully integrated concrete facilities: Statfjord A, Statfjord B and Statfjord C. Statfjord A, centrally located on the field, started production in 1979. Statfjord B, in the southern part of the field, in 1982, and Statfjord C, in the northern part, in 1985. The satellite fields Statfjord Øst, Statfjord Nord and Sygna have a dedicated inlet separator on Statfjord C. A PDO for Statfjord Late Life was approved in 2005.

The recovery strategy is based primarily on pressure depletion, but this is accompanied by a simultaneous expansion of both the gas cap above the oil zone and the underlying water zone. Some gas is also reinjected. Produced water was reinjected into the northern part of the Troll Vest oil province from 2000 to 2016.

TROLL
|
Status
|
More than two million reservoir metres have been drilled on Troll. Drilling of new oil production wells on Troll concluded altogether in 2023; however, the need for future oil wells will be considered regularly. A new gas compressor module on the Troll C platform started in 2020 to increase gas production and processing capacity. The production from the first stage of the Troll Phase III development started in 2021. The development includes eight new gas production wells on Troll Vest and a flowline to the Troll A facility.

TROLL
|
Reservoir
|
Troll contains very large amounts of gas resources and is also one of the largest oil producing fields on the Norwegian continental shelf. The field has two main structures: Troll Øst and Troll Vest. About two-thirds of the recoverable gas reserves lie in Troll Øst. The gas and oil reservoirs in the Troll Øst and Troll Vest structures consist primarily of shallow marine sandstone of Late Jurassic age in the Sognefjord Formation. Part of the reservoir is also in the underlying Fensfjord Formation of Middle Jurassic age. The field consists of three relatively large, rotated fault blocks. The eastern fault block constitutes Troll Øst. The reservoir depth at Troll Øst is 1330 metres. Pressure communication between Troll Øst and Troll Vest has been proven. Originally, the oil column in Troll Øst was mapped to be 0-4 metres thick. A well drilled in 2007 proved an oil column of 6-9 metres in the Fensfjord Formation in the northern segment of Troll Øst. The Troll Vest oil province originally had a 22 to 26-metre-thick oil column under a small gas cap, located at a depth of 1360 metres. The Troll Vest gas province originally had an oil column of 12-14 metres under a gas column of up to 200 metres. The oil column is now reduced to a thickness of only 1 to 5 metres. A significant volume of residual oil is encountered directly below the Troll Vest oil column.

TROLL
|
Development
|
Troll is a field in the northern part of the North Sea. The water depth is 300-330 metres. Troll was discovered in 1979, and the initial plan for development and operation (PDO) was approved in 1986. The plan was updated in 1990 and involved the transfer of gas processing to the Kollsnes terminal. The production started in 1995. A phased development was pursued for the Troll field, with Phase I recovering gas reserves in Troll Øst and Phase II focusing on the oil reserves in Troll Vest. Troll Phase I has been developed with Troll A, which is a fixed wellhead and compression platform with a concrete substructure. Troll A receives power from shore. The gas compression capacity at Troll A was increased in 2004/2005, and again in 2015. Troll Phase II was developed with Troll B, a floating concrete accommodation and production platform, and Troll C, a semi-submersible accommodation and production steel platform. The oil is produced from several subsea templates tied-back to Troll B and Troll C by flowlines. The production from Troll C started in 1999. The Troll C platform is also utilised for production from the Fram field. Several PDO amendments were approved in connection with various subsea templates at Troll Vest. A PDO for Troll Phase III (gas production from Troll Vest) was approved in 2018 and the production started in August 2021. An amended PDO for power from shore to Troll Vest was approved in 2021.

Yme is a field in the southeastern part of the Norwegian sector of the North Sea, 130 kilometres northeast of the Ula field. The water depth is 100 metres. The field comprises two separate main structures, Gamma and Beta, which are 12 kilometres apart. Yme was discovered in 1987, and the plan for development and operation (PDO) was approved in 1995. Yme was originally developed with a jack-up drilling and production platform on the Gamma structure and a storage vessel. The Beta structure was developed with a subsea template. The production started in 1996 and ceased in 2001, because operation of the field was no longer regarded as profitable. A PDO for the redevelopment of Yme was approved in 2007. The development concept was a new mobile offshore production unit (MOPU). Due to structural deficiencies and the vast amount of outstanding work to complete the facility, it was decided to remove it from the field in 2013. The removal of the MOPU was completed in 2016. In 2018, an amended PDO for the redevelopment of Yme was approved. The PDO includes a jack-up rig equipped with drilling and production facilities installed on the Gamma structure and a subsea template on the Beta structure, as well as reuse of existing facilities on the field. The production started again in 2021.

ÅSGARD
|
Reservoir
|
Åsgard produces gas and considerable amounts of condensate mainly from Jurassic sandstone at depths of as much as 4850 metres. The reservoir quality varies in the different formations, and there are large variations in the reservoir properties between the four accumulations. Smørbukk is in a rotated fault block and contains gas, condensate and oil in the Åre, Tilje, Tofte, Ile and Garn Formations. Smørbukk Sør contains oil, gas and condensate in the Tilje, Ile and Garn Formations. The Midgard gas accumulation is divided into four structural segments, with the main reservoir in the Ile and Garn Formations. Blåbjørn contains oil at a depth of 3100 metres in the Upper Cretaceous Lysing Formation. The Blåbjørn reservoir is located above Smørbukk Sør.

ÅSGARD
|
Status
|
Work is ongoing to increase the recovery from the field, with focus on a further reduction of the inlet pressure on the facilities and identification of new targets for infill drilling. Challenges for Åsgard are avoiding minimum flow in the subsea flowlines and depleted reservoirs that impact the drilling window. Subsea gas compression has has accelerated and prolonged gas production at Åsgard. Phase II of the subsea gas compression development is ongoing. New tie-ins to Åsgard, such as Blåbjørn and Smørbukk Nord, can prolong the lifetime of the facilities.

The Åsgard field includes the accumulations Smørbukk, Smørbukk Sør, Midgard and Blåbjørn. The field has been developed with subsea wells tied-back to a production, storage and offloading vessel (FPSO), Åsgard A. The development also includes Åsgard B, a floating, semi-submersible facility for gas and condensate processing. The gas centre is connected to a storage vessel for condensate, Åsgard C. The production started in 1999. An amended PDO for a subsea template at Smørbukk Sør was approved in 2004. A PDO for subsea gas compression at Midgard was approved in 2012, and the facility started operation in 2016. PDO exemptions for Blåbjørn and Smørbukk Nord were granted in 2023. The Åsgard facilities are an important part of the Norwegian Sea infrastructure. The Mikkel and Morvin fields are tied to Åsgard B for processing, and gas from Åsgard B is sent to the Tyrihans field for gas lift. The Trestakk field is tied-back to Åsgard A.
