Total will make between 50 and 70 employees redundant in Norway in the wake of its takeover of Maersk Oil, a news report said.
A spokesman for the French energy major said the merger and its sale of its interests in the Martin Linge field to Statoil had affected its staffing requirements, according to Norwegian media outlet Aftenbladet.
Total has been contacted for comment.
Paris-headquartered Total confirmed the completion of the acquisition last week.
At the time, a spokesman for Total E&P UK said no final decision had been made on the optimum headcount for the north-east of Scotland operation.
Both businesses employed about 700 people in exploration and production in Aberdeen when the deal was announced in August.
Total chief executive Patrick Pouyanne said last year that the merging of the two businesses would create “the opportunity to do some rationalisation”.
