EurOil: Denmark's top gas field now fully operational

Denmark’s largest gas field Tyra is finally fully operational again following multiple delays, one of its developers reported on November 10.

Operator TotalEnergies restarted gas production at Tyra in March, after substantial upgrades lasting four and a half years that faced delays related to the COVID-19 pandemic. There were further complications following its relaunch, however, with TotalEnergies reporting technical problems with a power transformer in May. This resulted in a slower-than-expected ramp-up to full production capacity.

Project partner BlueNord said in a statement this week that it had been informed by TotalEnergies that all necessary machinery at the field was not fully operational. This paves the way for the field to reach its full production plateau by the end of the year.

Tyra was closed down in September 2019 to allow the replacement of topsides at the field’s platforms, which over many years of production had subsided. New jacket extensions were also installed. The redevelopment programme was originally scheduled for completion in 2022, but global supply chain issues caused by the COVID-19 pandemic delayed key work at an Indonesian shipyard, as well as other tasks. The cost of the project also rose as a result of these complications, from DKK21bn to DKK25.7bn ($3.5bn).

Tyra is Denmark’s only major gas field, accounting for about 90% of national supply. At peak it will produce 2.1bn cubic metres per year of gas at peak, which is roughly a third higher than the country’s gas consumption in 2023. Thanks to the field’s relaunch, Denmark has therefore switched from heavily reliance on gas imports to becoming a net exporter once more.

The field is also set to produce a maximum of 22,000 barrels per day (bpd) of condensate.

“I am very pleased that Tyra II has achieved full technical capacity, and we can begin the ramp-up to plateau production before the winter season,” BlueNord COO Miriam Lykke commented. “With Tyra's upgraded facilities, we expect a significant reduction in CO2 intensity and a lower unit operating cost.”

TotalEnergies operates the Tyra field with a 43.2% stake, while BlueNord holds 36.8% and Nordsofondon the remaining 20% stake.
