NatGas production falls back to prior levels!

In one of the most unusual events since Robry started published his results many years ago, natgas production jumped by 5 bcf for a week and then in one day fell back 5 bcf. This VERY unusual event has brought lots of comments. Robry commented that line pressures and reporting of pipeline flows could be the source of the usual data. (see his post for more details).
My view is that the pipelines were over pressured (natgas was being stored in the pipes) and this extra storage was 'used up' as the cold weather increased demand. This low pressure will also increase production. Some data errors could have been a contributing factor. Thus, three seemingly unrelated factors combined for a dramatic change in natgas production.
(Note: this is a guess and not much more).
