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.

• For further information, see Best Available Monitoring Methods and Missing Data Reporting.

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.
