The Barnett Shale gas play refers to an extensive gas development project covering portions of at least 18 counties1  in the northeast portion of the Bend arch Fort Worth Basin in Texas. Production occurs from organic rich shales of the Mississippian aged Barnett shale.   The Newark East field is the field designation established by the Texas Railroad Commission for productive portions of the Barnett Shale Play area.

==History==

==History==

The Newark East field was discovered in 1981 by Mitchell Energy Corporation (acquired by Devon Energy).  The development of the field started slowly, and only 100 wells were completed between 1981 and 1990.  In 1998, a major breakthrough in completion techniques occurred when water fracturing replaced gel fracturing.  From 1997 to 2006, more than 5829 wells were put on production, and hundreds of additional wells were drilled, completed, or waiting on a pipeline.  Vertical wells were the primary drilling method until 2002 when seven experimental horizontal wells were drilled.  The excellent success of these wells prompted many operators to move their drilling mode from vertical to horizontal.  The early development of the fields (up until 2007), is outlined by Martineau.<ref>Martineau, D.
