This page provides an overview of the Subpart W reporting requirements for the enhanced oil recovery injection pump blowdown source type.

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.

The emissions from the enhanced oil recovery injection pump blowdown source type are applicable to the Onshore petroleum and natural gas production industry segment (98.236(a)(2)).

Indicate if the facility has the source type via the radio buttons

If the facility has the source type, then indicate whether missing data procedures were used.

Reporting Requirements

Table W.1 EOR injection pump system characterization and emissions must be completed by all facilities with the source type subject to reporting under 98.232. For each sub-basin at the facility, report:

• Sub-Basin ID [98.236(w)(1)]

• EOR injection pump system identifier [98.236(w)(2)]

• Pump capacity (barrels per day) [98.236(w)(3)]

• Total volume of EOR injection pump system equipment chambers, Vv (cubic feet) [98.236(w)(4)]

• Number of blowdowns per year [98.236(w)(5)]

• Density of critical phase EOR injection gas, Rc (kg/ft³) [98.236(w)(6)]
• Mass fraction of CO₂ in critical phase EOR injection gas [98.236(w)(7)]
• CO₂ emissions (mt CO₂) [98.236(w)(8)]

 

Table W.2 Missing data procedures used for EOR injection pump blowdown calculations is required if your facility relied on missing data procedures to develop your reporting for this source type:

• Unique name or ID number
• Sub-Basin ID [98.236(w)(1)]

• Parameters

• Measurement Frequency

• Number of quarters missing data procedures were used [98.236(bb)(1)] (required only if the measurement frequency was quarterly)

• Total number of hours in the year missing data procedure was used [98.3(c)(8)], [98.236(bb)(2)] (required unless the measurement frequency was quarterly, annually, biannually, or N/A)
• Procedures used to determine missing data [98.235(h)]

Total Emissions

The total emissions roll-up at the top of the sheet reflects the sum of each gas emission reported for the source type. These summations are calculated automatically by the Smart Form and tabulated on the Introduction tab.
