The Energy Information Administration (EIA) will be modifying the methodology it uses to estimate production data to, among other things, use more recent data from non-sampled companies. See here. For more, see this WSJ article: "But the Energy Information Administration, the statistical unit of the Energy Department, has uncovered a fundamental problem in the way it collects the data from producers across the country—it surveys only large producers and extrapolates its findings across the industry. That means it doesn't reflect swings in production from hundreds of smaller producers." The belief is that EIA has overestimated production as a result - and that these changes will correct the issue.
