Too wrong for too long? Production predictions just two years ago about shale energy have proven to be way off, writes Sandy Fielden at RBN Energy LLC.
Fielden: "If we look back to see what folk were forecasting for North American energy markets two years ago in 2011 and then compare that to today’s actual data and forecast, what would that tell us about the changing pace of North American energy production?
"Looking at the data from Bentek – produced as always at the time in good faith based on what the market was telling them – we see that the scale of change going on in North American energy production exceeded everyone’s expectations.
"We looked at crude oil production forecasts in the Williston Basin and the Eagle Ford, the natural gas production forecast in the Marcellus and the US NGL production forecast from Bentek around the time of the June 2011 Benposium.
"What we found was that in every case – crude oil, natural gas and NGLs - today’s forecast numbers for what we expect by 2016 are at least double what they were back in 2011....
