The Brynhild project is an offshore field linked to the Pierce field, which is operated by Shell in British waters.
Lundin, a Swedish energy company, said progress was moving slower than expected because of issues related to the commissioning of a floating production, storage and offloading vessel by Shell.
"We are disappointed and frustrated that the Haewene Brim FPSO is still not ready to accept Brynhild production," Lundin President Ashley Heppenstall said in a statement Monday.
Developments in Norway, one of Europe's largest oil and gas producers, represent more than 70 percent of the production forecast for Lundin. The company in April said it spent roughly $127 million on exploration programs during the first quarter of the year without much success.
"The delay in first production has clearly impacted our 2014 production guidance but we still retain our production guidance for 2015 of approximately 50,000 barrels of oil equivalent per day," Heppenstall said.
Lundin said Brynhild should still start operations in late 2014 despite the setback.
