A Warm Welcome to our Website

We specialise in the drafting and negotiation of international petroleum agreements.  Our clients include governments, NOCs, IOCs, and contractors of various sizes.  With over thirty years' experience advising on petroleum agreements across the globe we bring unique insight to the practical and commercial realities of the upstream.

We are privileged to be involved in some of the world's largest and most important petroleum transactions and invite you to explore our website to learn more about our services.

We provide specialist advisory, drafting and negotiation services to the international oil and gas industry.  

Our current business titles include Fundamentals of Upstream Petroleum Agreements (2008) and Commercial Contracts (2001).


We run a number of worldwide courses and conferences on upstream petroleum agreements and more general commercial topics.


This is a serious business but we like to have as much fun as possible.  Visitors may enjoy our Articles, or Chris Thorpe's series: Tales from the Arena and Tails of a Manx Cat.
