The dramatic turnaround is the result of a massive logistics undertaking, as Europe began bringing in gas from places including the U.S. and Qatar in an effort that has roiled energy markets. Dozens of liquefied natural gas tankers are floating offshore European ports.

Europe’s comfortable position could be temporary. Rough winter weather could boost demand, driving up prices and cutting into supplies.
