Prior Year - Enhanced Oil Recovery Hydrocarbon Liquids Dissolved CO2

Please see Reporting Form Instructions on downloading the blank reporting form and uploading the completed reporting form.
You may also refer to Optional Calculation Spreadsheet Instructions to download the Subpart W calculation spreadsheet.

This page provides an overview of the Subpart W enhanced oil recovery hydrocarbon liquids dissolved CO2 source category reporting requirements.

The enhanced oil recovery hydrocarbon liquids dissolved CO2 source category is applicable to Onshore Petroleum.

Indicate if the facility has the source type via the radio buttons.
  • If the source type is present you must report required elements.

If the facility has the source type, the Best Available Monitoring Methods and Missing Data table must be completed.
Reporting Requirements

For each sub-basin, the facility must report:

  • Sub-basin ID - the pick list for this data element is populated based on the Sub-Basin Selection Tab.  Be sure a valid Sub-basin ID is used.
  • Annual CO2 emissions (98.236(c)(18)(iii)
  • Volume of crude oil produced (barrels per year) (98.236(c)(18)(i ))
  • Amount of CO2 retained in hydrocarbon liquids (mt CO2 per barrel) (98.236(c)(18)(ii))

Total Emissions

The total emissions roll-up at the top of the sheet reflects the sum of the CO2 equivalents of each gas emission reported for the source type.  These summations are reflected and aggregated on the Introduction tab.
