Barnett shale gas unconventional play
The Barnett shale is considered the birthplace of the shale gas industry. It is primarily a dry gas play, located west of Dallas surrounding Fort Worth. The Barnett Core is located in Johnson, Tarrant, Denton, and Wise counties. The most productive area is East Tarrant due to high thermal maturity and a thick reservoir. The Barnett Combo, in the northeast part of the play (Cooke, Montague, and Wise counties), is more liquids-prone than the rest of the Barnett.
