Gulf Arab energy companies issued a record $28.7 billion in debt in 2017 to fund expansion plans as borrowing costs declined. State-owned oil and gas producers in Saudi Arabia, Kuwait, and the UAE plan to spend over $600 billion on energy projects in the next 5-10 years. Abu Dhabi National Oil Company raised $3 billion and Kuwait National Petroleum Company borrowed $6.2 billion for refinery and other projects. Record debt levels are expected to continue in 2018 as Gulf states invest heavily in energy infrastructure and production.
