Judith Aldersey-Williams has 25 years' experience as a commercial lawyer in London and Aberdeen.  She advises energy industry clients in the UK and internationally on commercial contracts, including joint operating agreements, major infrastructure projects, gas sales agreements, supply and service contracts and has worked on projects from Angola to Trinidad (she’s still hoping for a project in Zambia).  She also advises on regulatory issues and competition/antitrust matters. 

Her career highpoints have been advising Oil & Gas UK in its negotiations with the UK Government over the introduction of ground-breaking contracts to guarantee tax relief for decommissioning and advising the Subsea Well Response Project, a group of nine multinational oil companies, on contracts for the development and funding of innovative equipment which is now available to allow operators around the world better to respond to well control incidents like Macondo.
