Fr...So we need to know how long the laterals are. <br /><br />From the 9/2011 SGEIS:<br /><br />QUOTE: Current drilling technology for onshore consolidated strata results in maximum lateral lengths that do not greatly exceed the depth of the well. For example, a 5,000-foot deep well could generally not have a lateral length of significantly greater than 5,000 feet.24 This may change, however, as drilling technology continues to evolve. The length of the horizontal wellbore can also be affected by the operator’s lease position or compulsory integration status within the spacing unit, the configuration of the approved spacing unit and wellbore paths, and other factors which influence well design. ENDQUOTE<br /><br />Cabot says in Susquehanna County the laterals are commonly 4,500-4,900 ft, and they are planning on going longer:<br /><br />http://waytogoto.com/wiki/index.php/Cabot_Oil_and_Gas_Corp<br /><br />Data for Susquehanna County suggests the Marcellus is between 5,000-7,000 ft deep, so this seems consistent with the SGEIS.<br /><br />The Manning's water well in Franklin Forks was 4,000 feet away from the nearest well, so this indicates impacts to houses can occur at least 4,000 ft away.Bill Huston 1https://www.blogger.com/profile/15288627254805985954noreply@blogger.com
