AbstractThis report presents a digital map of tight-gas resource
assessments in the United States as part of the U.S. Geological Survey’s (USGS) National Assessment of Oil and Gas Project. Using a geology-based assessment methodology, the USGS quantitatively estimated potential volumes of undiscovered, technically recoverable natural gas resources within tight-gas assessment units (AUs). This is the second digital map product in a series of USGS unconventional oil and gas resource maps. The map plate included in this report can be printed in hard-copy form or downloaded in a Geographic Information System (GIS) data package, including an ArcGIS ArcMap document (.mxd), geodatabase (.gdb), and published map file (.pmf). In addition, the publication access table contains hyperlinks to current USGS tight-gas assessment publications and web pages.
IntroductionThe U.S. Geological Survey (USGS) carries out scientific
investigations and conducts assessments of geologically based energy resources, including unconventional resources (for example, shale gas, tight gas, unconventional oil, and coalbed methane). These scientific studies are used to evaluate and assess the quality and distribution of energy resource accumu-lations and the undiscovered, technically recoverable energy resource potential of the United States (U.S.). This publication summarizes the results of the U.S. tight-gas assessment in a geospatial map and data package.
The total petroleum system (TPS) is the basic geologic unit of the oil and gas assessment; it includes all of the
essential elements and processes needed for oil and gas accu-mulations to exist, including the presence of source and reser-voir rocks, hydrocarbon generation and migration, traps and seals, and undiscovered accumulations. An assessment unit is a mappable volume of rock within a total petroleum system in which discovered and undiscovered resource accumula-tions are relatively similar with respect to geology, exploration strategy, and risk characteristics (Ahlbrandt, 2000, no page numbers). Tight gas is natural gas trapped in formations with very low permeability to gas (0. 1 mD or less) due to fine grain size and poorly connected pores.
Comprehensive geologic studies, supporting data, and reports on the methodology used in assessing undiscovered oil and gas resources in the United States are available at the USGS Central Energy Resources Science Center website at: http://energy.usgs.gov/OilGas/AssessmentsData/NationalOil-GasAssessment.aspx

This is the second digital map product in a series of USGS unconventional oil and gas resource maps. The map can be printed in hardcopy form or downloaded in a Geographic Information System (GIS) data package, including an ArcGIS ArcMap document (.mxd), geodatabase (.gdb), and published map file (.pmf). In addition, the publication access table contains hyperlinks to current USGS tight-gas assessment publications and web pages.

Web ServicesThis report also includes a web map service. To access
the tight-gas web service, visit the USGS National Assessment of Oil and Gas Resources website at http://energy.usgs.gov/OilGas/AssessmentsData/NationalOilGasAssessment.aspx.
Download Maps and DataThe map of assessed tight-gas resources is available as
a GIS map and data package that is contained on CD-ROM or can be downloaded from the USGS website at http://pubs.usgs.gov/dds/dds-069/dds-069-hh/ or http://dx.doi.org/10.3133/ds69HH. The ArcMap document, whose filename contains an .mxd extension, is the main component of the GIS data package and is used to analyze geospatial data, symbol-ize features, and create maps. Access to the .mxd file requires Esri’s ArcGIS 10 or newer versions of the desktop software (Esri, 2000). Using the published .mxd and the ArcGIS Pub-lisher extension (ESRI, 2008a) in ArcMap, a special file called a published map file was created. Published map files contain a .pmf extension, and can be accessed using any ArcGIS (Esri, 2000) desktop product, including the free ArcReader (Esri, 2008b) application. ArcMap and ArcReader offer different ways to view a map, in which one can perform map-based tasks. ArcReader provides basic tools for map viewing, print-ing and querying of geospatial data. More advanced geospatial processing requires the ArcGIS suite of geospatial processing programs, including ArcMap.
There are two ArcMap documents contained in this report: (1) TightGasMap2014.mxd, and (2) TightGasMap-2014simplified.mxd. TightGasMap2014.mxd is a complex ArcGIS project used to build, design, and export the .pdf map. Multiple data frames enable the advanced user to navigate each province area; upon initial launch, this file tends to be much slower than subsequent map starts. TightGasMap-2014simplified.mxd is designed for a novice GIS user to easily navigate and utilize these data.
The digital map layout of both the .mxd and the .pmf contains a map window with a series of layers in the table of contents frame on the left side of the navigation screen. Within the table of contents, select the box to the left of each layer or group of layers to display the features in map view. Click the “+” sign to the left of each layer, group, or data frame to display the symbology or the list of layers within that group or data frame. To deselect the entire group, ctrl-click the check box to the left of any one of the AU names. Ctrl-click again to toggle the check boxes on for the entire group.
By default, the map is in Layout View, and Contiguous U.S. (lower 48) is the active data frame. Layout View is designed to work with the map layout and graphic elements, such as titles, north arrows, and scale bars, along with the data frame, all of which are arranged on a page. Data View is designed for exploring, displaying, and querying the data sets
presented on the map, which is displayed in real-world coordi-nates (Esri, 2011). Navigation between Layout View and Data View is available from the View drop-down menu.
Labels and annotation for the AUs are included as sepa-rate layers that can be toggled on and off, as deemed appro-priate for a particular map display. In the simplified .mxd, the ‘Tight-Gas AU Annotation’ layer, when visible, shows all tight-gas AU names. Users may wish to zoom into a particu-lar area of interest, in which case, individual province labels available within each province group can be toggled on and the AU annotation layer can be toggled off (made invisible).
ArcMap documents (.mxd) and published map files (.pmf) can be enhanced by including auxiliary base map layers, many of which are available as ArcGIS services (for example, shaded relief, world imagery; Esri, 2010). Several base layers are visible upon opening the map document, and setup as the default view. An important base layer, geologic units from the Geologic Map of North America (Reed and others, 2005; Garrity and Soller, 2009), is included for addi-tional geologic context. Because many of these base layers are very large files, toggling these layers off can hasten map display while navigating the interactive map. Once an appro-priate map graphic has been created or area of interest has been isolated the addition of one or more of the base layers can enhance the final map product or view.
All geospatial data are stored in file geodatabase (Esri, 2012; TightGas2014.gdb and BaseLayers.gdb) and shapefile format in a World Geodetic System (WGS) 1984 projection, which is a standard projection for distributing geospatial data. The polygons in TightGas2014.gdb represent the tight-gas AUs that have been defined and assessed by the USGS. An important aspect of this map product is that it does not require extensive GIS expertise or highly specialized equipment to use.
The Metadata folder contains tight-gas data documenta-tion in XML, html, and text format. The base map layers have metadata incorporated from the published sources. Reference or base layers from “The National Atlas of the United States of America” (U.S. Department of the Interior, 2008) include state and county boundaries, streams, water bodies, and urban areas in the United States. For the ArcGIS.com web services (for-merly ArcGIS Online; Esri, 2010), data descriptions, sources, and credits are stored as layer properties.
SummaryThe USGS map of the principal tight-gas resources in
the United States portrays the occurrence of this important resource. Estimates of the tight-gas resource, especially the portion that is technically recoverable, are likely to change over time as our geologic understanding of the resource char-acteristics increases, and with further advances in recovery methods. New information can be readily added to this digital baseline developed for the USGS National Assessment of Oil
4 Map of Assessed Tight-Gas Resources in the United States, 2014
and Gas project. The ability to view, edit, create, and analyze geospatial data can enhance/increase our understanding of tight-gas resources and assessments.
AcknowledgmentsThis report is a compilation of work by many USGS
Energy Resources Program geologists who presented the geologic evidence critical to defining and assessing tight-gas resource volumes across the United States. The manuscript was improved by reviews from Christopher J. Schenk, Jon Haacke, and Dave Ferderer, and thanks are extended to them for their thoughtful evaluations and suggested revisions.
