Tim O’Hanlon

Born in Ireland, Tim received his Civil Engineering degree from University College Dublin and joined Schlumberger, which served as his earliest introduction to the oil business. Following further studies in Reservoir Engineering at Imperial College London, he became a member of the founding team of Irish startup Tullow Oil in the mid 1980’s. 


From the outset, this exciting and ambitious explorer/producer focused on Africa, operating oil and gas opportunities which had proved non-commercial for the IOC Majors. During these early years at Tullow, Tim lived in Senegal, heading up the company’s onshore, oil & gas, production business cash-cow, splitting his time between wearing coveralls/hard-hat and a suit/tie. 


More recently as Vice President for Africa, Tim helped to drive Tullow’s rapid expansion across the Mother Continent involving ground-floor licence negotiations, the velvet acquisitions of Energy Africa and Hardman, and finally Tullow’s fabled frontier exploration of some of Africa’s more remote interior basins. During these years, Tim was more likely to be found in the Ministerial waiting rooms of Brazzaville or Bujumbura than in the oil company data rooms of Houston or London. Over the course of Tim’s 33 years at the company – during which he was widely known as “Tullow’s Monsieur Afrique” – Tim visited all but one of Africa’s 54 countries (Djibouti) and negotiated with dozens of Africa’s Heads of State.
