Uisdean has nearly thirty five years involvement in upstream oil and gas, both UK and International. An LLb (Hons) graduate of Edinburgh University, his interest in the oil and gas business developed studying for an LLM in Oil & Gas in Louisiana State University, Baton Rouge, Louisiana. Qualifying at the Louisiana Bar, Uisdean spent five years doing mostly US oil and gas litigation. The next ten years were spent in Argentina, Venezuela and Brazil, during which Uisdean focused on oil and gas transactional work. Since returning to the UK in 2003, he has pursued both UKCS (and UK onshore) and international opportunities. Much of his international work has occurred in the African continent. He is fluent in Spanish and Portuguese.
In the North Sea, Uisdean advises on deals such as farm-in/outs, Asset SPAs and corporate acquisitions. He also advises on the related JOA, UOA and commercial contracts such as transportation and processing agreements (TPA) and gas sales. On the regulatory side he is an expert on the new maximising economic recovery(MER) regulatory regime, introduced as a consequence of the Wood Review, the MER Strategy and the Energy Act 2016. With strong experience in the evolving UK onshore regime, Uisdean is a noted specialist on third party access to offshore infrastructure and the decommissioning regulatory system.
In the international realm, Uisdean advises on granting instruments, deals and commercial agreements such as JOAs. He has also frequently been involved in advising financiers and nomads on the oil and gas aspects of capital and loan financing for petroleum projects. Uisdean has also advised governments and national oil companies, including, for instance, the Province of Nova Scotia on a third party access to infrastructure regime.
Uisdean has extensive knowledge of all kinds of oil service and oil construction contracting, having worked with many oil companies and supply chain companies.
Uisdean is a member of the AIPN and serves as the AIPN Co-ordinator for Scotland. He has also been recently appointed as one of three Co-chairs of the AIPN drafting Committee for the new Asset SPA Model Form. Uisdean has co-authored one chapter (on MER) and contributed another chapter (on third party access) to the 3rd edition of Oil and Gas Law: Current practices and Emerging Trends by Gordon, Paterson and Usenmez. A frequent writer and broadcaster on oil and gas issues and trends, Uisdean continues to act as an outside advisor to Louisiana State University Law School.
