Area Oil & Gas Tool: Comparison Analysis Oklahoma DEQ Thursday, January 14, 2016

Topics Compared in this Presentation Production  Total Liquids  Total Gas Emissions (Exploration + Production)  Total VOC  Total Nox Statewide Emissions Estimates for 2011, 2014, and 2014 with Subpart W data 2

Comparison Analysis: Production For this topic: 3 Dataset Label Description 2011 HPDI 2013 activity data from the November 2014 version of the 2011 NEI Tool 2014 HPDI 2015 activity data from the December 2015 version of the 2014 NEI Tool 2014W Activity data from the Subpart W spreadsheets ONLY

Comparison Analysis: Production Data for 2011 & 2014 was taken from the tool inputs activity tables.  Input data is not affected by Subpart W data Data for 2014W was taken from the Subpart W spreadsheets (sent out by Jennifer Snyder in early December 2015)  For Liquids: Condensate Tanks Excel file  For Gas: NO PRODUCTION DATA, only activity factors (well counts, # of wells venting/flaring, etc.) 4

Total Liquids Production

Total Liquids Production (TLP) “Total” liquids production includes:  Oil  Condensate  Condensate CBM Units of BBL (1 barrel of oil = 42 gallons) 6

Total Liquids Production (TLP) (2014 – 2011) = 52,453,278 BBL (2014W – 2014) = -36,058,487 BBL  This makes sense because Subpart W is a subset of the HPDI data, and there are less counties 7 DatasetStatewide TLP (BBL)# of Counties ,866, ,319, W81,261,17840

Total Liquids Production (TLP) Key points: 1.Discrepancy: Eight counties have higher Subpart-W TLP than 2014 TLP to 2014 production increase is centered in eastern & northern Anadarko Basin (along the eastern part of the Woodford Shale) 13

Total Gas Production

“Total” gas production includes:  Casinghead (Associated Gas)  Gas Well gas  CBM Units of MCF (thousand cubic feet) No gas production data in Subpart W, ONLY activity factors (well counts, # of wells venting/flaring, etc.)  Comparison is between 2011 & 2014 tool inputs only 15

Comparison Analysis: Emissions

For this topic: 21 DatasetDescription 2011 Emissions data from the EIS Staging Tables populated by the November 2014 version of the 2011 NEI Tool 2014 Emissions data from the EIS Staging Tables populated by the December 2015 version of the 2014 NEI Tool Includes effects of adding Subpart W data

Comparison Analysis: Emissions 2011 Tool is built with Exploration & Production, while 2014 has separate Tools for Exploration & Production FOR THIS ANALYSIS, the Exploration & Production for 2014 have been combined (so a direct comparison can be made between 2011 & 2014) 22
