The June EIA gas production numbers put US gas production at 69.47 billion cubic feet per day. See www.eia.gov. Production in 2010 was the highest since 1973, and the June 2011 production was the 4th month of increased production and from high previous levels.
What is causing the near record production?
Not high gas prices. Gas has declined from $13 in July 2008 to less than $4 per thousand cubic feet now.
Shale gas production is the answer and increasingly from the Marcellus which is now producing about 4 billion cubic feet per day or about 6% of total production. And this enormous shale gas production is happening at current low, low gas prices.
