TotalEnergies Discovers New Gas in Denmark

French oil major TotalEnergies on Tuesday said that it has discovered additional gas condensate resources in the new well at the Harald field in the Danish North Sea, which could start producing through the existing Harald and Tyra facilities before the end of 2024.

Located in shallow waters, 250 km off the west coast of Denmark, the Harald East Middle Jurassic (HEMJ-1X) well was drilled in the Eastern part of Harald field and encountered 48 meters of net gas condensate pay in a good quality reservoir.

TotalEnergies said the HEMJ-1X well will be immediately connected to the Harald platform and is expected to start producing before the end of the year through the existing Harald and Tyra facilities.

Kevin McLachlan, Senior Vice President Exploration at TotalEnergies, said that the success of the Harald East Middle Jurassic well, nearby the Harald facilities in Denmark, demonstrated the strength of their Exploration strategy.

This additional discovery at the Harald field will contribute to Danish energy supply by boosting our existing production in the North Sea in line with the Danish National Compromise, he said.

The well is expected to be brought on stream in connection with the Tyra start-up, developed by Danish Underground Consortium. Gas from the Tyra hub is exported to Europe through two pipelines to Nybro in Denmark and Den Helder in the Netherlands.

TotalEnergies is the operator of the Danish Underground Consortium with a 43,2% working interest, alongside joint venture partners BlueNord (36,8%) and Nordsøfonden (20%).

Increased Output

Miriam Lykke, Chief Operating Officer in BlueNord, said that they were pleased with the preliminary results from the HEMJ well and were looking forward to the well, being completed and on production.

Pending further data and final results, the HEMJ well is expected to increase production from the Harald field in the Danish Underground Consortium, extend the life of the Harald hub and contribute to energy security of supply in Denmark and Europe,” she added.

According to Offshore Engineer magazine, Maersk Oil discovered Tyra in 1968, 225 km west of Esbjerg, the seaport city in Denmark.

However, the gas production was suspended in September 2019 for the overhaul project, which involved decommissioning of existing facilities and commissioning of eight new platform topsides, two jackets and six bridges.

About 98.5% of the materials recovered from the removed installations have been reused or recycled, TotalEnergies claimed.

According to BlueNord, the redevelopment will also unlock gross reserves of more than 200 MMboe, extend field life by 25 years, and decrease operating expenses and emissions intensity. The license currently expires in 2042.

The focus now is on bringing the Tyra fields and the Valdemar, Roar, Harald and Svend satellites back onstream, said BlueNord COO Marianne Eide, with an expected ramp-up period of four months.
