U.S. natural gas inventories posted their smallest build so far of the current injection season, reducing the surplus over the five-year average to its lowest level in two months. Gas in underground storage increased by 15 billion cubic feet last week to 3,184 Bcf, the EIA reports. The storage build was below the five-year average for the week of 33 Bcf, and smaller than the 21 Bcf estimate in a WSJ survey of analysts. Stocks were 167 Bcf above the 2012-2025 average, compared with a surplus of 185 Bcf the previous week. Nymex natural gas is up 2% at $2.898/mm Btu.
