Sept 5 (Reuters) -U.S. natural gas storage is on track to end the April-October summer injection season at a four-year high of 3.908 trillion cubic feet (tcf) on Oct. 31, according to analysts' estimates.

That compares with 3.809 tcf at the end of the summer injection season in 2023, 3.929 tcf in 2020 and a five-year (2019-2023) average of 3.747 tcf.

Looking ahead to the end of the November 2024-March 2025 winter withdrawal season, analysts project storage will fall to 1.775 tcf on March 31, the lowest in three years.

That compares with an eight-year high of 2.289 tcf of gas in storage at the end of the winter withdrawal season in 2024, 1.401 tcf at the end of March 2022 and a five-year (2020-2024) average of 1.874 tcf.

The 384 active storage fields in the Lower 48 states had a design capacity of 4.666 tcf in November 2023, according to the latest federal data available.

The following lists analysts' storage estimates in trillion cubic feet with the most recent estimates on top:
