  6. 6. Sources included/not included in the Upstream O&G sector <ul><li>Includes all emissions sources in the: </li></ul><ul><ul><li>Exploration and production (E&P) sector of oil & natural gas, as well as: </li></ul></ul><ul><ul><ul><li>Gas gathering, collection, and processing - through to the “tailgate” of Natural Gas Processing Plants </li></ul></ul></ul><ul><ul><ul><li>Crude Oil Transportation (including pipelines, trains, trucks, and marine vessels) to the “entry gate” of Oil Refineries </li></ul></ul></ul><ul><li>Does not include : </li></ul><ul><ul><li>Oil refining and downstream distribution of petroleum products </li></ul></ul><ul><ul><li>Transmission, storage and distribution of natural gas downstream of the processing plant </li></ul></ul><ul><li>Includes all companies involved in any way in E&P, natural gas processing, and/or crude oil transportation, including: </li></ul><ul><ul><li>Oil and Gas leaseholders </li></ul></ul><ul><ul><li>Support services contractors (e.g., drilling contractors) </li></ul></ul>
  7. 7. Oil Industry Sector Upstream O&G Protocols do not address oil operations shown in the shaded area. Gathering Separation & Distribution Gas Treating Facilities Gas Exporting Facilities Oil & Gas Distribution Oil Refineries Oil Exporting Facilities Pumpjack Production Transmission Storage & Distribution Processing Drilling & Completion Injection (Water, Steam, Gas) Water Handling Including Steam
  8. 8. Natural Gas Industry Sector Upstream O&G Protocols do not address natural gas operations shown in the shaded area. Distribution Engine Compressor Stations Separator Gas Plant Liquids Liquids to Distribution LNG Underground Storage Well Compressor Stations Gas Production Processing Transmission, Storage & Distribution Drilling & Completion Exploration C C
  9. 9. Facility Issue Addressed in Protocol work to date <ul><li>Definition of a facility/Aggregation of emissions: </li></ul><ul><ul><li>Proposed Solution: Dispersed emission sources to be aggregated, at a minimum, to “production field” level: </li></ul></ul><ul><ul><ul><li>Production field is a well understood, broadly accepted concept within the industry </li></ul></ul></ul><ul><ul><ul><li>Production fields are precisely defined by state, province, or country </li></ul></ul></ul><ul><ul><li>Reporters are given the option of aggregating multiple fields together (particularly useful, e.g., for infrastructure common to more than one field) </li></ul></ul><ul><ul><li>Emissions from sources corresponding to standard definition of a facility (e.g., natural gas processing plants) must be reported by facility </li></ul></ul>
