It consists of sedimentary rocks. The productive part of the formation is estimated to stretch from the city of Dallas west and south, covering 5,000 square miles (13,000 km²) and at least 18 counties. Some experts say that the Barnett ... In summary, the fluid flow in shale formation is controlled both by the pore size and by the properties of pore walls (surfaces). Due to the larger Vt, V2, V3, and smaller surface areas, as well as the high carbonate and illite content, the shales from Es 4 upper possess better production potential (Figures 10D,E). Significances and Prospects Maximum thickness is about 366 m in Iosco and Arenac Cos just north of Saginaw Bay, but is generally 305 m in the eastern two-thirds of the basin and thins to about 168 m in the western third.
