    * This total does not include wells without geographic coordinates because these wells were not included in the geodatabase feature class prior to 2017. For more information on the number of wells that are missing location information, see question two below.<\/th>\n<\/tr>\n<\/tfoot>\n<\/table>\n\n

    Note: Prior to 2015, production reports were\u00a0released twice a year (for January-June and July-December), so the number of producing wells only changed in Q2 and Q4 updates. \u00a0Starting in 2015, production was reported monthly, 45 days after the end of the month. Therefore, Q1 and Q3 versions of the data include all wells that produced gas up to the end of January and July, respectively.\u00a0 Data versions from Q2 and Q4 include all wells that produced gas up to the end of June and December, respectively.<\/p>\n<\/div>\n<\/li>\n

    * Location error only includes wells without geographic coordinates. Prior to 2017, this error was determined using a different algorithm and may not be accurate.<\/th>\n<\/tr>\n<\/tfoot>\n<\/table>\n\n

    Because not every data source includes records for every unique well, discrepancies are inherent. It is recommended that every effort be made by users to investigate and\/or disregard records that may skew one\u2019s research or analysis.<\/p>\n

    Wells are analyzed for errors based on the following criteria:<\/p>\n
