Discoveries from Exploration Activity
Despite only 13 wells being drilled in 2015, seven of them were successful, discovering just over 150 million boe
of technically recoverable reserves. While these discoveries are yet to be fully appraised, it is likely that they will
produce a number of commercially viable development opportunities, although some prospects will require an
improvement in market conditions before reaching that stage.
