Future natural gas supplies in the United States are at highest reported level on record according to a report released last week. Future gas supply totals 3,978 trillion cubic feet in 2022, an increase of 3.6 percent from the comparable year-end estimate in 2020. The Potential Gas Committee assesses the natural gas resource potential for each of 90 geologic provinces comprising six geographic areas of the Lower 48 States and Alaska, 56 of which are onshore and 34 offshore.
