Reporting on Oil

Here's a story that shows the value of the Freedom of Information Act:

The U.S. government faces shortcomings in producing its oil-inventory data, according to internal Department of Energy documents, casting doubt on figures that affect the production and prices of the world's most important industrial commodity.

The documents, obtained through a Freedom of Information Act request, expose several errors in the Energy Information Agency's weekly oil report, including one in September that was large enough to cause a jump in oil prices, and a litany of problems with its data collection, including the use of ancient technology and out-of-date methodology, that make it nearly impossible for staff to detect errors. A weak security system also leaves the data open to being hacked or leaked, the documents show.

....On Sept. 16, the EIA released data showing almost four million barrels of oil had vanished from the Cushing storage hub in Oklahoma during a single week. The market paid particular attention because Cushing is the nation's most important commercial storage facility. Its oil is used to fill orders from buyers on the New York Mercantile Exchange. Oil futures jumped 2.2% after the report.

But out of the sizable drop at Cushing, 1.7 million barrels represented a correction made after the EIA discovered a previous error in one company's reporting, according to the emails. James Beck, who heads the team that conducts the weekly survey, confirmed the correction in an interview.

Good to know.
