Sigma Commercial Consulting was formed in 2008 by James Black and Ashley Horobin. Recognising the limitations and potential shortcomings of the traditional "body shop" approach to consutling, our aim was to provide a broader package of solutions to the upstream and midstream oil and gas industry. Clients can now choose a tailored package that best suits their needs.
 
In addition to our core commercial resource, we can also provide access to legal expertise, economic modelling, hydrocarbon accounting and mediation support.
 
We have also developed a comprehensive and unique range of training courses. We run open courses each year and also provide bespoke in-house training for oil companies and legal firms.
