10. What our Partners have said....... “I am delighted with Northern’s first successful development in the Netherlands. It shows there is still sufficient gas potential in the Netherlands and it is another step towards our goal of producing 30 bcm from small fields by 2030.” Chairman of the Executive Board of EBN, Jan Dirk Bokhoven “Dyas congratulates Northern Petroleum with this important milestone of reaching first gas on the Grolloo field. This is an important step into unlocking reserves from similar small gas pockets in the Netherlands that were previously considered not to be economically attractive.” Peter Veenhof, Managing Director Dyas
