In 2011, Dragon's turnover increased by 47% from $780.4 million (£494m) to $1.15 billion (£728m) while profits were up 68% to $648.4m (£410m).
Dragon, majority owned by Dubai's Emirates National Oil Company, confirmed last week it was in the early stages of making an offer for Edinburgh-based Bowleven, which has the bulk of its interests in Cameroon.
