EnSys Energy is an independent consulting firm specializing in the “downstream” petroleum industry. We cover crude and non-crudes supply, refining, crude and product logistics, trade and oil markets, providing highly quantitative strategic assessments and outlooks. These focus on capacity, operations, technology, economics, markets, logistics and regulatory factors. With clients as varied as the DOE, DOS, EPA, CFTC, American Petroleum Institute, OPEC Secretariat, midstream, major oil and technology companies, together with extensive expert witness work, we have established a reputation for independence, objective and thorough analysis.

Our fuels/regulatory track record dates back to the late 1980’s. Our current main focus is on marine fuels and the impacts of the IMO 2020 Sulphur Rule together with projections through 2040 in support of the 2019 OPEC World Oil Outlook.

Acknowledged for over 30 years as leaders in the evaluation of North American markets in a global context, we have become heavily involved in assessments relating to the major supply and logistics developments occurring in the USA and Canada. This has led to a series of key analyses and on-going services and enables us to bring to bear an exceptional level of understanding of US and Canadian crude oil logistics and markets.
