Canadian firm VERMILION ENERGY TRUST will be buying up 89.88% of the stock held by ESSO SAF, French subsidiary of EXXON MOBIL, in ESSO REP (ESSO oil research and exploration company) for around USD 161 million. This acquisition is expected to enable the French production company VERMILION ENERGY to increase its daily output of barrels by 3500 on average this year. The French subsidiary of VERMILION will therefore produce the equivalent of 9700 barrels a day, 45% of total French production.
