The supply as of June 3 totaled 23.4 million barrels of oil, a fall of 1.6 million from May 27 when the total was 25 million barrels.
One year ago, Cushing had a supply of 45.7 million barrels of crude oil.
Ever since the first of the year when Cushing held 34,838,000 barrels of oil, the supply has been sliding downward according to the EIA.
