Increases in drilling efficiency have contributed to the breakdown of traditional methods that seek to estimate oil and natural gas production based principally on rig counts. The Drilling Productivity Report (DPR) analyzes drilling efficiency using the average number of wells a rig can drill over a period of time (left chart above) as well as a measure of how productive each new well is expected to be (right chart above).
