On Thursday, the U.S. Energy Information Administration said that natural gas storage fell by 14 billion cubic feet last week, compared to expectations for a drop of 13 billion cubic feet.
Inventories increased by 11 billion cubic feet in the same week a year earlier, while the five-year average change for the week was a build of 15 billion cubic feet.
Typically this time of year, stockpiles begin to climb as milder spring temperatures curb demand for natural gas.
Total U.S. natural gas storage stood at 1.673 trillion cubic feet as of last week, 32.5% lower than last year at this time and 3.8% below the five-year average for this time of year.

Inventories rose by 21 billion cubic feet in the same week a year earlier, while the five-year average change for the week is a rise of 39 billion cubic feet.
Nymex gas prices have risen sharply in recent weeks, gaining almost 30% since mid-February, boosted by calls for colder temperatures in major consuming regions across the U.S. that helped tighten the market.
Still, some analysts have warned that further gains may be limited with spring's low-demand shoulder season looming.
The heating season from November through March is the peak demand period for U.S. gas consumption. Nearly 50% of all U.S. households use gas for heating.
Gas use typically hits a seasonal low with spring's mild temperatures, before warmer weather increases demand for gas-fired electricity generation to power air conditioning.
