Final Report (Revised): 2007 Oil and Gas Industry Survey Results, Final Report (Revised), October 2013 (posted November 1, 2013)

The 2007 Oil and Gas Industry Survey was mailed out to crude oil and natural gas production, processing, and storage facilities in California. The survey was completed by 325 companies representing over 1,600 facilities and approximately 97 percent of the 2007 crude oil and natural gas production in California. Emissions were calculated using equipment information from the survey and commonly used emission equations and emission factors listed in Appendix B of this report. Total emissions for equipment covered under this survey are estimated to be 17.7 million metric tons of CO2e. Combustion sources (equipment burning fuel for energy) account for 93 percent of the total CO2e emissions. The remaining 7 percent of the CO2e emissions, or about 1.3 million metric tons of CO2e, come from vented and fugitive sources, which are intentional and unintentional releases of gases to the atmosphere, respectively.

The following are archived materials related to the survey. These documents, including the Final Report (Revised) above, are available for download in the Supporting Documents section.
