Today's Trends: O&G Well Productivity Declines

Crude oil well productivity rose sharply in the 1960s and reached a peak of 18.6 b/d per well in 1972, according to the U.S. Energy Information Administration (EIA) Annual Energy Review 2009. After 1972, productivity trended downward to a 55-year low. The 2008 rate of 9.4 b/d per well was 51 percent of the 1972 peak. In 2009, productivity rose to 10.1 b/d per well.


Natural gas well productivity, measured as gross withdrawals per day per well, grew rapidly in the late 1960s, peaked in 1971, and then fell sharply until the mid-1980s. Productivity remained fairly steady from 1985 through 1999, fell annually through 2008, and turned up slightly in 2009.

So the up tick in 2009 the beginning of a trend. With the shale gas revolution, long reach wells hitting a lot of pay can we expect productivity per well to improve? It would seem so.

Why do you think the productivity levels have dropped over the past 30 years? What are the variables that influenced the trend? Thank you
