DNO, a Norwegian oil and gas operator, has announced the resumption of production at the Trym field in the Norwegian North Sea.

The field, part of licence PL147, was shut down for five years due to redevelopment work on the Tyra field infrastructure in the Danish North Sea.

Production from Trym was temporarily halted in September 2019 due to the redevelopment project at the Tyra field.

This development is expected to boost North Sea output significantly.

First commissioned in 2011, Trym is expected to contribute approximately 3,000 barrels of oil equivalent per day (boepd) net to DNO at its peak.

The remaining reserves are estimated at two million barrels of oil equivalent (mboe) net to DNO. DNO operates Trym with a 50% stake, while Sval Energi holds the remaining 50%.

The available capacity at the Trym subsea template presents further opportunities.

DNO is currently evaluating the development of the 2013 Trym Sør discovery, which contains recoverable resources of around 2mboe net to DNO, potentially adding production from early 2027.

Additionally, DNO has identified nearby exploration prospects that may be drilled from the Trym subsea template, potentially extending the field's lifetime.

Trym is located in the southern part of the Norwegian sector in the North Sea, 3km from the Danish sector border, at a water depth of 65m.

The field was discovered in 1990, and the plan for development and operation (PDO) was approved in 2010.

The field is developed with a subsea template that includes two horizontal production wells tied to the Harald facility in the Danish sector.

The well stream is processed at the Harald facility for further transport through the Danish pipeline system via the Tyra field.

In related developments, Harbour Energy has commenced production at its Talbot development, a three-well subsea tieback located around 16km south-east of the Judy platform in the UK North Sea.

Harbour Energy holds a 67% stake in this development, while Ithaca Energy owns the remaining 33%.
