U.S. Energy Information Administration Drilling Productivity Report Summary (August 2018)

Core Content

The U.S. Energy Information Administration (EIA) publishes the Drilling Productivity Report for key tight oil and shale gas regions, providing insights into production trends and drilling productivity. The report includes data through July and projections for September, highlighting changes in oil and natural gas production.

Methodology and Notes

• Data Sources:
  • Drilling Info provides production, permit, and spud data.
  • Baker Hughes reports rig and well counts.
  • State-level agencies (e.g., North Dakota Oil and Gas Division, Railroad Commission of Texas, etc.) provide well production, permit, and completion data.
• Monthly additions from one average rig:
  • Reflects the estimated contribution of an average rig to production from new wells.
  • Calculated using historical data from the previous months, lagged by two months.
• Legacy production change:
  • Represents changes in production from existing wells, influenced by depletion rates and other factors like freeze-offs or hurricanes.
• Projected change in monthly oil/gas production:
  • Combines new-well and legacy production changes.
  • Does not account for external factors like infrastructure constraints or environmental issues.
• EIA Approach:
  • Does not distinguish between oil-directed and gas-directed rigs as wells may produce both.
  • New wells are defined as those that began production in the previous month.
  • Reworked and recompleted wells are excluded from new-well calculations.

Key Information

• New-well oil production per rig varies by region, with the Permian Region showing the highest increase at +34 thousand barrels/day.
• New-well gas production per rig is also highest in the Permian Region at +54 thousand cubic feet/day.
• Legacy production changes are influenced by well depletion and other temporary disruptions.
• Total production includes both new and legacy wells, with data sourced from state agencies and EIA estimates where necessary.
• The report provides a month-over-month comparison for each region, with color-coded arrows indicating growth or decline.

Footnotes

1. Oil production includes crude and condensate from all formations in the region.
2. Gas production includes gross (before processing) production from all formations.
3. Rig count is calculated from Baker Hughes' weekly data.
4. New well is defined as one that began producing in the previous month.
5. Rig count data lags production data due to the time required for wells to begin production after drilling.
