U.S. Energy Information Administration | Petroleum Marketing Monthlyii March 2018 Preface ThePetroleum Marketing Monthly(PMM) provides information and statistical data on a variety of crude oils and refnedpetroleum products. The publication presents statistics on crude oil costs and refned petroleum products sales for useby industry,government, private sector analysts, educational institutions, and consumers. Data on crude oil include thedomestic frst purchase price, the f.o.b. and landed cost of imported crude oil, and the refners’ acquisition cost of crude oil.Refned petroleum product sales data include motor gasoline, distillates, residuals, aviation fuels, kerosene, and propane.The Offce of Petroleum and Biofuels Statistics, U.S. Energy Information Administration ensures the accuracy, quality, andconfdentiality of the published data in the Petroleum Marketing Monthly. Scope of data The data within thePetroleum Marketing Monthlyare compiled from fve Energy Information Administration (EIA) surveyforms. The crude oil statistics are calculated from data collected on the following three survey forms: Form EIA-182,“Domestic Crude Oil First Purchase Report”; Form EIA-856, “Monthly Foreign Crude Oil Acquisition Report”; and Form EIA- 14, “Refners’ Monthly Cost Report.” The statistics on petroleum product sales prices and volumes are derived from Form EIA-782A, “Refners’/Gas PlantOperators’ Monthly Petroleum Product Sales Report.” The data presented in Tables 45 to 47 are derived from aggregations of data from Form EIA-782C, “Monthly Report of PrimeSupplier Sales of Petroleum Products Sold for Local Consumption.” Sections Monthly statistics on purchases of crude oil and sales of petroleum products are presented in the Petroleum MarketingMonthly in six sections:HighlightsSummary StatisticsCrude Oil PricesPrices of Petroleum ProductsVolumes of Petroleum ProductsPrime Supplier Sales Volumes of Petroleum Products for Local Consumption. The publication highlights salient statistics for the United States in the Summary Statistics section. More detailed geographiccoverage occurs in the other four sections. Geographic coverage for crude oil includes country of origin for foreign crude andPetroleum Administration for Defense (PAD) Districts and individual States for domestic crude oil. Geographic coverage ofthe petroleum products includes PAD Districts and individual States.Detailed statistics for crude oil, including the price of imported crude oil by country of origin, by gravity, and by crude stream,can be found in the Crude Oil Prices section. PAD District and/or State-level statistics for petroleum products are presented in the Prices, Volumes, and Prime SupplierSales of Petroleum Products sections. To aid the reader in determining the market changes, the majority of the tables showdata for the report month and previous month for the current year, and the report month for the previous year. Notes on the tablesFor the crude oil statistics referencing Form EIA-182, United States includes the 50 States, the outer continental shelf,and the District of Columbia. For crude oil statistics referencing either Form EIA-14 or Form EIA-856, United StatesU.S. Energy Information Administration | Petroleum Marketing Monthlyiii March 2018 includes the 50 States, the District of Columbia, Puerto Rico, the Virgin Islands, and all American territories andpossessions. For the petroleum products data, United States includes the 50 States and the District of Columbia. Prices exclude taxes. Refer to the Explanatory Notes for a tax table on motor fuels.Some of the tables use state abbreviations. Refer to the Explanatory Notes for a table of U.S. Postal State abbreviations.Sales of leaded gasoline are a component of averages and totals prior to October 1993.References to “Refners” include gas plant operators (see the Glossary for defnition of “Gas plant operators”).“Prime supplier” refers to a frm that produces, imports, or transports any of the selected petroleum products acrossState boundaries and local marketing areas and sells the product to local distributors, local retailers, or end users.The category “Retail outlet” refers to any company-operated outlet selling gasoline, on-highway diesel fuel, or propanefor on-highway vehicle use (see Glossary).No. 2 distillate volumes and prices are classifed in accordance with what the product was sold as, regardless of theactual specifcations of that product (see defnitions of No. 2 distillate in the Glossary).Beginning with the February 2007 data release, EIA revised the table formats and content for thePetroleum MarketingMonthly(PMM) to eliminate oxygenated gasoline as a separate category and to revise the categories of diesel fuel(i.e., ultra-low sulfur, low sulfur, and high sulfur). In conjunction with these changes, the Total columns in certain PMMtables have been eliminated to help ensure that sensitive data reported to EIA by individual survey respondents maynot be closely estimated using the aggregates published by EIA. Refer to the Product Guide for new table numbers.As of January 2012, EIA changed the methodology used to calculate the initial price estimates for refner acquisitioncosts of crude oil. The price estimate for domestic crude oil comes from a regression model based on West TexasIntermediate (WTI) crude oil spot market prices. The price estimate for imported crude oil comes from a regressionmodel that uses a basket of world crude oil prices. The composite price estimate is a weighted average of the domesticand imported prices based on refnery receipts data found inthePetroleum Supply Annual .Final revisions to 2010 and 2011 monthly and annual values in Tables 1, 1A, and 18-27 were added to thePetroleumMarketing Monthlyin the March 2013 issue.As of the March 2016 data release, January and February 2016 OPEC and Non-OPEC crude oil prices in Tables 21 and22 were revised to include Indonesia in OPEC and exclude it from Non-OPEC.Beginning with the November 2017 data release, due to the increase of crude oil activity in the North Dakota region,EIA replaced the North Dakota Sweet Crude Stream on the EIA-182, Domestic Crude Oil First Purchase Report withthe predominant North Dakota Bakken Crude Stream to provide an accurate price estimate for an important highvolume crude stream regularly traded in domestic crude oil markets.
