Downstream

Downstream refining and marketing of petroleum and petrochemical products is a dynamic business driven by the shift in economic prosperity of developing nations and changing energy demand patterns globally.

Many of the traditional downstream players are divesting their assets in developed markets, whilst new projects are beginning to be developed in the higher growth markets of Asia. Developments in the Middle East, particularly in petrochemicals (including ethylene, propylene, aromatics, acetyls and fertilizers), continue to generate significant opportunities.  All these factors make this an exciting industry to work in, and one that requires its advisers to have sector–specific knowledge backed up by a global resource capability. 

Allen & Overy has been at the forefront of this market, advising IOCs, NOCs and host governments, sponsors, funders (equity and debt), and contractors on market leading transactions globally.
