Drilling Productivity Report Summary

Core Content

This report provides an analysis of drilling productivity and production changes in seven key tight oil and shale gas regions in the United States for the period of March 2018, with data projected through April. It includes data on new-well and legacy production, as well as monthly changes in production. The report uses data from multiple sources and is based on estimates rather than actual figures, considering factors like well depletion, freeze-offs, and other external influences.

  • Gas: 1,186 thousand cubic feet/day (April) vs. 1,186 thousand cubic feet/day (March)

Main Points

• New-well production is calculated using historical data and is estimated based on the rig count lagged by two months.
• Legacy production reflects changes from existing wells, primarily influenced by depletion rates, but also affected by external factors like freeze-offs or hurricanes.
• Monthly additions from one average rig show the average contribution of a rig to production from new wells.
• Projected production changes combine the effects of new-well and legacy production, excluding external influences such as infrastructure issues or environmental constraints.

Key Information

• Data Sources:

  • Drilling Info for real-time rig location and production data
  • Baker Hughes for rig and well counts
  • State oil and gas agencies for well production, permit, and completion data

• Report Methodology:

  • Uses monthly average rig counts from Baker Hughes
  • Estimates new-well production based on historical data
  • Includes all formations in the regions, not limited to tight or shale formations

• Footnotes:

  • Oil production includes both crude and condensate
  • Gas production is gross (before processing)
  • New wells are those that began production in the previous month
  • Reworked and recompleted wells are excluded from calculations

Conclusion

The report highlights the monthly changes in oil and natural gas production across various regions, emphasizing the role of new and legacy wells in overall production trends. It provides a comprehensive view of the industry's performance, using data from multiple sources and methodologies to ensure accurate estimations.
