Tullow Oil is to drill an exploration well on the Kiarsseny Marin licence off Gabon in Africa.
This follows the farm-out of a 42.5% interest in the block to Addax Petroleum. Tullow will remain as the operator with 57.5% of the block.
Drilling will start later this month to test a southern extension of an area with proven oil reserves. Addax will bear the drilling costs.
