Dan’s love of invention from a young age led him to pursue a career in engineering, which now spans over 20 years, eight of which he worked at Petroleum Engineering Services (PES) where he directed a world-class team designing intelligent wells. After PES was acquired by Halliburton, Dan jointly established Petrowell, where an inspiring company ethos resulted in pioneering solutions and the company eventually being purchased by Weatherford.
Dan’s ability to think outside the box has resulted in a number of world firsts and new technologies coming to market. Recognised as one of the best innovative thinkers in his peer group, he has over 50 granted patents and has won the Significant Contribution Award at the Offshore Achievement Awards in recognition of his influence on the industry.
