This document presents guidance for conducting integrated GHG emissions and energy management audits at oil and natural gas facilities. Procedures are presented for focusing efforts on the types of facilities and operations most likely to offer opportunities for significant cost effective improvements.

While the document highlights standard approaches for controlling GHG emissions and improving energy efficiencies, it also identifies specific operational issues or problems to watch for that can be contributing to unaccounted for emissions, product losses and process inefficiencies. Relevant standards, guidelines and best management practices are referenced wherever possible to provide the reader with access to more detailed information on available control technologies and measurement or assessment techniques.
