Changes to the Petroleum Supply Monthly (PSM) data for January 2020

Originally Released: March 27, 2020

Updated: April 30, 2020

The U.S. Energy Information Administration (EIA) made the following changes to petroleum supply data effective in Petroleum Supply Monthly (PSM) data released on March 31, 2020.

  • EIA discontinued collecting survey data and reporting stocks of propylene held at bulk terminals. Beginning with monthly data for January 2019, U.S. and regional stocks of propylene reported by EIA include only barrels of propylene held at refineries; barrels of propylene held at bulk terminals are excluded. EIA also recalculated quantities of stock change and demand measured as product supplied using only stocks of propylene held at refineries. EIA discontinued reporting propylene stocks held at bulk terminals in order to eliminate the possibility of counting barrels of petroleum feedstocks delivered for use as input to petrochemical cracking units as demand measured as product supplied and then later counting the same barrels as bulk terminal stocks of propylene.

  • EIA discontinued collecting survey data on ending stocks, imports, and input to blending of methyl tertiary butyl ether (MTBE), ethyl tertiary butyl ether (ETBE), and other oxygenates. EIA continues to collect survey data on production of MTBE, ETBE, and other oxygenates. Beginning with monthly data for January 2019, EIA discontinued reporting U.S. and regional totals for production, imports, adjustments, stock change, input to blending, and exports of MTBE, ETBE, and other oxygenates in supply and disposition tables and other tables of the PSM, including Petroleum Navigator tables and EIA’s API, on the EIA website. EIA will continue to report U.S. and regional fuel ethanol production, import, adjustment, stock change, input, and export quantities in supply and disposition tables and other tables in the PSM and on Petroleum Navigator as in the past. EIA continues to report production of fuel ethanol, MTBE, and other oxygenates (for example, aliphatic alcohols and aliphatic ethers intended for fuel blending other than fuel ethanol and MTBE). EIA discontinued collecting and reporting data (other than production) on MTBE, ETBE, and other oxygenates because only small quantities of these products have been blended into fuel in the United States since 2006. EIA also wanted to eliminate double counting isobutane and isobutylene barrels as both product supplied of isobutane and isobutylene and also as production of ethers in supply and disposition tables. Note that import and export quantities for MTBE, ETBE, and other oxygenates remain available in trade statistics from the U.S. Census Bureau.

  • EIA discontinued collecting survey data on stocks of residual fuel oil held by pipeline operators. Beginning with data for January 2020, EIA discontinued reporting stocks of residual fuel oil held by pipeline operators from U.S. and regional totals. U.S. pipeline operators reported very few barrels of residual fuel oil held as stocks, and U.S. total quantities ranged from 0–10 thousand barrels in every month after December 2008. EIA continues to report U.S. and regional totals of residual fuel oil stocks held at refineries and bulk terminals.

  • EIA incorporated these changes in the Weekly Petroleum Supply Status Report for the week ending April 10, 2020 that was published on April 15, 2020.
