Please note: This table lists initially reported production for both onshore and offshore wells. As additional late or corrected reports are received, the initially reported production volumes are subject to change. Some numbers below are reflected in thousands or billions of cubic feet as indicated. For example, actual gas well gas production for 2009 was 6,804,617,582,000 cubic feet. Also, actual gas vented or flared in 2008 was 42,800,000,000 cubic feet.
| Year | Gas Well Gas Production (in thousands of cubic feet (Mcf)) | Casinghead Gas Production (in thousands of cubic feet (Mcf)) | Total Natural Gas Production (in thousands of cubic feet (Mcf)) | Number of Producing Gas Wells | Gas Vented or Flared (in billions of cubic feet (Bcf)) | Natural Gas Reserves as of Jan. 1 (in billions of cubic feet (Bcf)) |
