OSLO, Norway  ConocoPhillips has permission from Norway’s authorities to start production from the Tommeliten A Field in the southern North Sea.

The development, with estimated investments of about NOK13 billion ($1.18 billion), is designed to recover about 150 MMboe.

Tommeliten A, discovered in 1977 southwest of the Ekofisk complex, is a mainly gas/condensate field in license 044, partly extending into UK waters.

Two subsea templates with slots for up to 12 wells are connected to Ekofisk, where the gas will be exported to Emden in northern Germany. Produced oil and wet gas will head via the pipeline system to Teesside in northeast England.

ConocoPhillips expects seven of the 11 development wells to be completed at startup, with the other four completed during first-quarter 2024. The 12th well slot will be retained for a potential future replacement well. 

Tomas Mørch, assistant director of license management in the Norwegian Petroleum Directorate (NPD), said the project has been completed ahead of schedule and within the cost framework.

“We also note that the same type of subsea technology used on Tommeliten A could potentially be applied for other development projects in the area,” Mørch said. 

Previous development attempts were unsuccessful, in part due to a lack of available processing capacity at Ekofisk, although that situation no longer applies, the NPD said.
