The company reported on Monday that revenue had increased by 151% to $1.5 billion, with a full year of production from the Ebok field contributing $1.15 billion, compared to $272 million in 2011.

Profits after tax also rose by 62% to $203 million, also due to ebok’s full-year output as well as an increase in production from the Okoro field.

Gross profit also took into account a $20 million impairment charge related to the write-off costs of the Nunya well on the Keta Block, offshore Ghana.
