Earlier this month, Qatar witnessed an historic milestone in the liquefied natural gas (LNG) industry when Ras Laffan Liquefied Natural Gas Company Limited (II) and ExxonMobil signed a Heads of Agreement (HOA) to provide the US with 15.6m tonnes of LNG per year. The deal is expected to bring some USD12bn to the country, the largest single investment in Qatar's growing energy industry. Furthermore, the project will see the country become the single largest supplier of LNG to the US market.
