EOG Resources Eagle Ford Reserve Potential

In its second quarter report, EOG Resources revealed a 45% increase in its Eagle Ford estimated potential reserves from 2.2 net BnBoe to 3.2 net BnBoe. This is the company’s third reserve increase in four years. EOG officials expect continued production growth in the Eagle Ford, with a current drilling inventory of 12 years.

In the report, company officials said the Eagle Ford Shale was a significant contributor to EOG’s U.S. crude oil production growth (33% year-over-year) and associated natural gas liquids (NGLs) growth (22% year-over-year). Natural gas production from the play was also credited as contributing to the company’s total production growth. See below for EOG’s U.S. production volumes for the quarter:

  • Crude Oil and Condensate – 274,600 b/d
  • NGLs – 78,500 b/d

    Excellent article, thanks for posting it. Are the reserve estimates being raised 45% due to an increase of EOG’s acreage or is it because EOG is raising the EUR of each individual eagle ford well ? essentially raising the recovery factor ? thanks, Rod
