NOTE:
The rigs from DeWitt County were inadvertently left out of the total Eagle Ford rig count in the August Drilling Productivity Report.

In this update, The Eagle Ford productivity and production estimates are being revised down due to two factors: the production volumes from the source were revised down and the anticipated impact from hurricane Harvey on the production, drilling, and completion activities in southeast Texas. The volumetric revision also impacted the Permian region but to a lesser degree.

 

The Drilling Productivity Report uses recent data on the total number of drilling rigs in operation along with estimates of drilling productivity and estimated changes in production from existing oil and natural gas wells to provide estimated changes in oil and natural gas production for seven key regions. EIA's approach does not distinguish between oil-directed rigs and gas-directed rigs because once a well is completed it may produce both oil and gas; more than half of the wells produce both.
