  2. Barnett Shale - Wikipedia

    en.wikipedia.org/wiki/Barnett_Shale

    Gas wells producing from the Barnett Shale of the Fort Worth basin are designated as the Newark, East Gas Field by the Texas Railroad Commission. From 2002 to 2010 the Barnett was the most productive source of shale gas in the US; it is now third, behind the Marcellus Formation and the Haynesville Shale .

  3. Newark Supergroup - Wikipedia

    en.wikipedia.org/wiki/Newark_Supergroup

    Newark, New Jersey. The Newark Supergroup, also known as the Newark Group, is an assemblage of Upper Triassic and Lower Jurassic sedimentary and volcanic rocks which outcrop intermittently along the east coast of North America. They were deposited in a series of Triassic basins, the Eastern North American rift basins, approximately 220–190 ...

  4. Bend Arch–Fort Worth Basin - Wikipedia

    en.wikipedia.org/wiki/Bend_Arch–Fort_Worth_Basin

    The fault system bisects the Newark East Field (NE-F) creating a zone of poor production in Barnett Shale gas reservoirs. Several faults that cut basement and lower Paleozoic rocks in the southern part of the province are identified at the Ordovician Ellenburger Group stratigraphic level.

  5. Shale gas in the United States - Wikipedia

    en.wikipedia.org/wiki/Shale_gas_in_the_United_States

    In 2007, shale gas fields included the #2 (Barnett/Newark East) and #13 (Antrim) sources of natural gas in the United States in terms of gas volumes produced. [2] The number of unconventional natural gas wells in the U.S. rose from 18,485 in 2004 to 25,145 in 2007 and is expected to continue increasing [ 3 ] until about 2040.

  6. Sourland Mountain - Wikipedia

    en.wikipedia.org/wiki/Sourland_Mountain

    Sourland Mountain was formed 200 million years ago by a plutonic intrusion of a hard igneous rock, diabase, into the Brunswick Shale. [8] The intrusion occurred as tectonic forces created the Newark Basin, a prehistoric rift valley active near the rift which ultimately spread North America and Africa apart. The parallel ridges of the mountain ...

  7. Hammer Creek Formation - Wikipedia

    en.wikipedia.org/wiki/Hammer_Creek_Formation

    The Hammer Creek Formation is conformably underlain by the New Oxford Formation, which is the basal unit of the Newark Supergroup in south-central Pennsylvania. The Hammer Creek is mapped from the southern borders of Dauphin and Lebanon Counties to the northeast to the Schuylkill River. A laterally equivalent rock unit called the Brunswick ...

  8. Gettysburg Formation - Wikipedia

    en.wikipedia.org/wiki/Gettysburg_Formation

    Gettysburg, Pennsylvania. Named by. Stose and Bascom, 1929 [1] The Gettysburg Formation is a mapped bedrock unit consisting primarily of sandstones, conglomerates, and shales. The Gettysburg Formation was first described in the Gettysburg area of Adams County, Pennsylvania in 1929, [1] and over the following decade was mapped in adjacent York ...

  9. Newark Basin - Wikipedia

    en.wikipedia.org/wiki/Newark_Basin

    The Newark Basin is one in a series of these failed rifts. It is a half-graben filled over time by characteristic red bed sediments, sediments eroded from the uplifted footwalls of the border faults that were deposited within the basin; they are red due to their abundance in oxidized iron oxide minerals. The border fault is the Ramapo Fault on ...
