Definition
An oil refinery is an industrial processing facility that converts crude oil into a range of usable petroleum products through distillation, cracking, reforming, and other chemical processes. Primary outputs include gasoline, diesel, jet fuel, heating oil, liquefied petroleum gas, and feedstocks for the petrochemical industry. Refineries operate through a series of processing units that separate crude oil into its component hydrocarbons by boiling point, then chemically transform heavier fractions into lighter, more valuable products. Refinery complexity is measured by the Nelson Complexity Index, with higher scores indicating greater ability to process heavy crude into premium products.
UAE Context
The UAE’s flagship refining asset is the Ruwais Refinery in Abu Dhabi, operated by ADNOC Refining. With a processing capacity of approximately 922,000 barrels per day following its 2015 expansion, Ruwais is one of the largest refineries in the world. The facility processes Murban and Upper Zakum crude grades into gasoline, diesel, jet fuel, naphtha, and base oils for domestic consumption and export. ENOC operates the Jebel Ali Refinery in Dubai with a capacity of approximately 210,000 barrels per day, supplying the emirate’s fuel and aviation needs. Together, these refineries enable the UAE to export refined products rather than solely raw crude, capturing significantly more economic value per barrel.

Vision 2031 Relevance
Refining capacity is integral to the UAE’s Vision 2031 goal of maximizing downstream value from its hydrocarbon resources. Rather than exporting crude oil as a raw commodity, the UAE captures additional margin by processing it into refined fuels and chemical feedstocks. The integration of refining with petrochemical production at Ruwais creates an industrial cluster that generates high-skilled employment, attracts international technology partners, and supports energy security by ensuring domestic fuel self-sufficiency. Future refinery upgrades focus on producing ultra-low-sulphur fuels and increasing conversion of residual fractions, aligning with both environmental standards and economic optimization.
