EIA begins monthly survey-based reporting of U.S. crude oil production

With the release of today’s Petroleum Supply Monthly, EIA is incorporating the first survey-based reporting of monthly U.S. crude oil production statistics. Today’s Petroleum Supply Monthly includes estimates for June 2015 crude oil production using new survey data for 13 states and the federal Gulf of Mexico, and revises figures previously reported for January through May 2015.

EIA estimates U.S. crude oil production in June 2015 at 9.3 million barrels per day, a decrease of approximately 100,000 barrels per day from the revised May 2015 figure. The latest Petroleum Supply Monthly includes downward revisions of 40,000 to 130,000 barrels per day for the months of January through May 2015. The largest-volume revisions include lower estimates of monthly oil production in Texas (ranging from about 100,000 to 150,000 barrels per day) and increases in the federal Gulf of Mexico (ranging from about 10,000 to 50,000 barrels per day).

“These survey-based estimates of U.S. oil production represent a significant improvement over our previous method of estimation” said EIA Administrator Adam Sieminski. “Domestic oil production has become an increasingly important part of energy supply in the United States, and this change in data collection gives the country a better way to assess the contribution of this resource.”

The expanded “Monthly Crude Oil, Lease Condensate, and Natural Gas Production Report” survey collects monthly oil production data from a sample of operators of oil and gas wells in 15 individual states and the federal Gulf of Mexico; production from all remaining states and the federal Pacific is reported collectively in an “other states” category. The states and regions individually surveyed include Arkansas, California, Colorado, Kansas, Louisiana, Montana, New Mexico, North Dakota, Ohio, Oklahoma, Pennsylvania, Texas, Utah, West Virginia, Wyoming, and the federal Gulf of Mexico. Revised survey-based crude oil production estimates were not provided at this time for two states included in the expanded survey, Oklahoma and West Virginia, because EIA has not completed validation of the new estimates for those states. EIA anticipates revising estimates for these states in the next few months.

Estimates of U.S. oil production by EIA have been based in the past on tax and other production data obtained directly from state agencies. Given the timetable for EIA’s data products, much of that information is lagged and incomplete at the time of initial publication. For several states, the time from a particular month’s originally reported production volume to when that same month’s reporting could be considered final (i.e., with no or very minimal further revisions) is several months to well over a year. The survey-based approach improves regional estimates by representing well over 90% of oil production in the United States. A detailed comparison of estimates using the expanded survey data and using the previous methodology for the 13 states is provided on the Monthly Crude Oil and Natural Gas Production webpage.

Crude oil production data collected on the expanded survey are used as inputs to several EIA products, including the Petroleum Supply Monthly and widely followed forecasts such as the Short-Term Energy Outlook and the Annual Energy Outlook. Crude oil production data continue to be available in its prior locations on EIA’s data pages and will also be presented on EIA’s Monthly Crude Oil and Natural Gas Production webpage alongside natural gas data from the expanded operator survey. Later in 2015, EIA will include estimates of monthly crude oil production by density, as measured by API gravity, for the individually surveyed states and the federal Gulf of Mexico.

The product described in this press release was prepared by the U.S. Energy Information Administration (EIA), the statistical and analytical agency within the U.S. Department of Energy. By law, EIA’s data, analysis, and forecasts are independent of approval by any other officer or employee of the United States Government. The views in the product and press release therefore should not be construed as representing those of the Department of Energy or other federal agencies.
