SHALE GAS PLAYS
in the US and Canada
|
History of Shale Gas Plays
The
first commercial gas well in the US was completed in New York's
Dunkirk Shale in 1821, and estimates indicate that over 28,000
shale-gas wells have been drilled in the United States since then.

|
The first Barnett Shale gas production, by Mitchell Energy &
Development Corp, took place in the Fort Worth Basin in 1981. Until
Barnett Shale successes, it was believed that natural fractures had
to be present in gas shale. A low-permeability gas-shale play is
presently viewed as a technological play. Advances in micro-seismic
fracture mapping, 3D seismic, horizontal drilling, fracture
stimulation and multiple frac stages, have all contributed to
successful gas shale wells.

By the early 2000’s the main gas shale plays to that point had been:
Antrim Shale in the northern Michigan Basin; Barnett Shale in the
Fort Worth Basin, Texas; Lewis Shale in the San Juan Basin; New
Albany Shale in the Illinois Basin; and the Ohio Shale in the
Appalachian Basin. More recent gas shale plays include the Woodford
Shale in Oklahoma; Fayetteville Shale in Arkansas; Haynesville Shale
in Louisiana; Marcellus Shale in the Appalachian Basin; Utica Shale
in New York; and Eagle Ford Shale in Texas. There are 57 United
States and Canadian gas-shale plays listed below.
In early 2011,
the latest exploration 'buzz' around New York, Ohio, Pennsylvania
and West Virginia concerns the Utica Shale.
