Prior Year - Gas Well Completions and Workovers

This page provides an overview of the Subpart W gas well completions and workovers source category e-GGRT reporting requirements.  Reporting is required for gas well completions with and without hydraulic fracturing, as applicable.

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 well completions and workovers source category is applicable to Onshore Petroleum and Natural Gas Production.

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 gas well completions and workovers with hydraulic fracturing, the facility must report the following for each sub-basin:

  • 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.
  • Well type (Horizontal or Vertical) (98.236(c)(6)(i))
  • Select the equation used to calculate emissions from gas well completions with hydraulic fracturing (Eq. W-10A and Estimated Flow Rates (based Eq. W-11A or Eq. W-11B), Eq. W-10A and Measured Flow Rates, Eq. W-10A and Both Estimated and Measured Flow Rates, or Equation W-10B) (98.236(c)(6)(i))
  • Select the equation used to calculate emissions from gas well workovers with hydraulic fracturing (Eq. W-10A and Estimated Flow Rates (based Eq. W-11A or Eq. W-11B), Eq. W-10A and Measured Flow Rates, Eq. W-10A and Both Estimated and Measured Flow Rates, or Equation W-10B) (98.236(c)(6)(i))

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.
