Modern hydraulic fracturing was developed here, and combining this technology with horizontal drilling created a boom in natural gas production that continued for more than a decade. Drillers discovered that they could increase the permeability of the shale by pumping water down the well under pressure that was . It consists of sedimentary rocks dating from the Mississippian period (354-323 million years ago) in Texas. The size of the the Barnett Shale is approximately 5000 square miles, and occurs at depths from 6500 to 8500 feet.

A collection of maps and charts of the Barnett Shale natural gas bearing formation in north central Texas from a variety of sources.These maps and charts are displayed for educational purposes only. Though a similar framework can be found in Xu and Payne (2009) for modeling carbonate rocks, this study focuses on a workflow determined by specific characterization of shales. Deep beneath the well-established cities of Dallas and Forth Worth lies this natural gas rich geological formation.

The Barnett Shale is a geologic feature found in north-central Texas underlying approximately 5000 square miles and at least 18 counties.9 It is directly beneath the Dallas-Fort Worth Metroplex. The Barnett shale of Texas was the first major natural gas field developed in a shale reservoir rock. 2005, the Barnett Shale alone was producing nearly 0.5 trillion cubic feet of natural gas per year. At a base price of $4 gas, the Barnett will produce approximately 44 trillion cubic feet (TCF) of natural gas through 2050 based on already drilled wells and the wells that will be drilled through 2030. The Barnett Shale was last assessed by the US Geological Survey (USGS) in 2003 and only included vertical drilling. Barnett Shale Formation Forecast to be a Major Contributor to US Natural Gas.

Barnett Shale is a hydrocarbon-producing geological formation consisting of sedimentary rocks and stretching from the Dallas-Fort Worth metroplex west and south, covering 5,000 square miles. Lack of correlation with distance to Barnett Shale horizontal wells, with distance to conventional wells, and with well density suggests a natural origin of the dissolved methane. The Barnett Shale (Mississippian) is the source rock for conventional reservoirs in north- central Texas and as an unconventional shale gas system is the source, seal, and reservoir for the largest gas field in the United States (Pollastro et al., 2007). Dan Steward , consulting geologist with Republic Energy in Dallas, Texas, served as a member of the Barnett shale team during his tenure at Mitchell Energy (1981-2001). The study's well sample is made up of about half of the 15,000 existing wells in the Barnett Shale, the geological formation outside Fort Worth that offers the longest production history for hydrofractured horizontal wells in the world. Firstly, we studied the average porosity of the used samples using CT Scanning. Method The workflow for our shale rock physics model is shown in Figure 1 (a) and the corresponding procedures and theories are illustrated in Figure 1 (b). Barnett The Barnett shale formation is the grandfather of shale gas plays. The shale consists of sedimentary rock made of clay and quartz. The Monterey Shale is an underground formation in California that the EIA touted as containing 15.4 billion barrels of recoverable oil. It is officially designated by the United States Geological Survey (USGS) as Province 045 and classified as the Barnett-Paleozoic Total Petroleum System (TPS). The Barnett is the most exploited shale play in the world; cumulative production to 2012 is 13 Tcf. Some of the maps may be incomplete or out of date. For most of the basin's history, bottom waters were euxinic, preserving organic matter and, thus, creating a rich source rock, along with . The study was conducted by the Bureau of Economic Geology (BEG) at the University of Texas at Austin and funded by the Alfred P. Sloan Foundation. In 2013, USGS released an updated assessment of the Bakken formation in . It consists of sedimentary rocks.
