Oil/Gas Emissions Workgroup: Phases I & II Inventories

Phases I & II Final Documents

In late 2005 the WRAP completed the Phase I oil and gas emission inventory project to estimate for the first time, emissions from these field operations. Emphasis was placed on generating the first complete and consistent area source estimates for this source category with the potential to impair visibility near Class I areas in the West, in particular NOx. Discussion of the results from Phase I, uncertainties identified, and the availability of additional data then led to the Phase II project, completed in Fall 2007. Phase II also focused on NOx and SOx emissions affecting regional haze planning.

Final Phase II O&G Inventory Report (03/31/08 correction) PDF (1 MB)
This is ENVIRON’s September, 2007 Final Report of the “WRAP AREA SOURCE EMISSIONS INVENTORY PROJECTIONS AND CONTROL STRATEGY EVALUATION – PHASE II”. The Report provides an overview of the Phase II project and then describes results from the five Project tasks:

  • Improvements to the 2002 O&G Field Operation Emissions Inventory
  • Updating Baseline O&G Field Operation Emissions from 2002 to 2005
  • Control Strategy Evaluation for O&G Field Operations
  • 2018 O&G Field Operation Emissions Forecasts
  • Improvements to O&G Point Source SOx Emissions Forecasts for 2018

Appendix A: Phase II O&G Inventory Report (10/4/07) XLS This is the “Example Controls Scenario for the San Juan Basin, New Mexico” spreadsheet referenced in Appendix A of the Report.
