EnSys Energy is an independent consulting firm specializing in the petroleum industry “downstream” from crude and non-crudes supply, refining, crude and product logistics, trade and oil markets. We provide strategic services where capacity, operations, technology, economics, markets and regulatory factors intersect. With clients as varied as the DOE, DOS, EIA, EPA, CFTC, American Petroleum Institute, Association of Oil Pipe Lines, OPEC Secretariat, midstream, major oil and technology companies, together with expert witness work both for and against industry, we have established a reputation for independence and for thorough, objective analysis.

Acknowledged for over 25 years as leaders in the evaluation of North American markets in a global context, we have in recent years 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.
