STAVANGER, NorwayTotalEnergies expects to produce first gas from  the Tyra redevelopment project in the Danish North Sea by March 31 or earlier, partner BlueNord said in its latest results statement.

Tyra II should deliver field opex of below $13/bbl in the first year of full production and 30% lower emissions intensity, while extending the life of the Tyra Field life by 25 years. In addition, the project should generate 2.8 Bcm/year, restoring Denmark’s former position as a net exporter of natural gas.

Among the recent achievements, the Harald platform was recently re-instated and the wells re-opened; Harald will be the first Tyra satellite to come on stream.

All wellheads have been re-installed on Tyra East and West with the first well unplugged on Tyra West last December. The next step will be to secure the Certificate of Compliance that is needed ahead of the introduction of methanol and gas from Dan.

Once Tyra II is onstream, ramp up to maximum technical capacity should be completed within four months.

As for other fields in the area, the workover campaign on Dan that started in mid-2022 should finish shortly. To date there have been 50 well interventions that have added 2P reserves of about 6.8 MMboe.

The workover rig Noble Reacher will continue operations at Halfdan, performing well optimization interventions throughout the year.

Two infill wells are being drilled from Halfdan using spare slots on the Halfdan A (HBA) platforms. The first well, HBA 27B, spudded in June 2023, but technical issues mean that first production has been pushed back to this April.

Late last year, the Skjold Partial Gas Acceleration Pilot (SGPAP) got underway. This involves changing the recovery mechanism in part of the field from water injection to pressure depletion.

SGPAP should increase gas production from the Gorm hub, and in preparation, gas export from Gorm has been established.
