The OPEC Monthly Oil Market Report for May 2021 was published this past week. The last month reported in each of the charts that follow is April 2021 and output reported for OPEC nations is crude oil output in thousands of barrels per day (kb/d). In most of the charts that follow there is a red (and in one case yellow) line without markers which is the centered twelve month average (CTMA) for output. Note that this a change from the way Ron Patterson has reported the average data for many years which used a trailing twelve month average. Essentially the curve shifts back in time by 5 months as I choose July as the center month for the January to December 12 month average.
