The fundamental geologic unit used in the 1995 National Oil and Gas Assessment was the play, which is defined as a set of known or postulated oil and or gas accumulations sharing similar geologic, geographic, and temporal properties, such as source rock, migration pathways, timing, trapping mechanism, and hydrocarbon type. The geographic limit of each play was defined and mapped by the geologist responsible for each province. The play boundaries were defined geologically as the limits of the geologic elements that define the play, such as the limits of the reservoir rock, geologic structures, source rock, and seal lithologies. The only exceptions to this are plays that border the Federal-State water boundary. In...

The Apparent Wilcox Group thickness maps are contoured from location and top information derived from the Petroleum Information (PI) Wells database. The Wilcox apparent thickness map was constructed by searching for Wilcox and Midway Group tops. Apparent thickness is computed by subtracting Midway top from the Wilcox top. Geographic control is superimposed on the maps from USGS state line, county, elevation and other data files. The veracity of the PI Wells database is being checked by comparison to published cross sections and geologic maps. Interpretation of the depth to Wilcox and apparent thickness maps along with published measured sections and cross sections indicates that portions of Texas, Louisiana, Mississippi...

The Pod (or pods) of Mature Source Rock is a critical element of the Total Petroleum System and incorporates all source rocks that potentially have generated hydrocarbons within the system. The Pod(s) of Mature Source Rock is shown here as a geographic boundary defined and mapped by the geologist responsible for the province, and incorporates the known limit of thermally mature, organic-rich source rock(s) that is responsible for generating and expelling discovered and undiscovered petroleum accumulations, shows, or seeps within the Total Petroleum System. The Pod(s) of Mature Source Rock boundary was mapped by the province geologist after studying the extent of the source rock facies and the temperature and burial...

![]() The surficial geologic map of the Eastern and Central United Statesdepicts the areal distribution of surficial geologic deposits and othermaterials that accumulated or formed during the past 2+ million years,the period that includes all activities of the human species. Thesematerials are at the surface of the earth. They make up the "ground"on which we walk, the "dirt" in which we dig foundations, and the �soil�in which we grow crops. Most of our human activity is related in oneway or another to these surface materials that are referred tocollectively by many geologists as regolith, the mantle of fragmentaland generally unconsolidated material that overlies the bedrockfoundation of the continent. The map is based...
The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar geologic, geographic, and temporal properties within the Total Petroleum System, such as source rock, timing, migration pathways, trapping mechanism, and hydrocarbon type. The Assessment Unit boundary is defined geologically as the limits of the geologic...
This map shows the structural configuration on the top of the Cotton Valley Group in feet below sea level. The map was produced by calculating the difference between a datum at the land surface (either the kelly bushing elevation or the ground surface elevation) and the reported depth of the Cotton Valley Group. This resulted in 10,687 wells for which locations were available. After deleting the wells with obvious data problems, a total of 10,504 wells were used to generate the map. The data are provided as both lines and polygons, and the proprietary wells that penetrate the top of the Cotton Valley Group are graphically displayed as quarter-mile cells. The well information was initially retrieved from the IHS...
This digital map database consists of the ESRI ARC/INFO Version 7.0.2 coverages used to generate the plates in Professional Paper 1538-M (1994). Base-data is from 1:2,000,000-scale Digital Line Graph (DLG) data (roads, railroads, streams, water bodies, and international boundaries) and 1:100,000 scale DLG data (state and county boundaries).

The coverages were created using the gridded data available fromthis ftp site. Most of the gridded data for the United States is ata spacing of 0.1 degrees latitude and longitude. The higherresolution data available for California, Nevada, and part ofArizona and Utah were used for both the U.S. and Western U.S. maps.The gridded data for this area is at a spacing of 0.05 degreeslatitude and longitude.
The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, hydrocarbon plays or assessment units are defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes. The province boundaries were drawn on the county lines that most closely followed the natural geologic boundaries.

This map shows the structural configuration of the top of the Travis Peak or Hosston Formations in feet below sea level. The map was produced by calculating the difference between a datum at the land surface (either the Kelly bushing elevation or the ground surface elevation) and the reported depth of the Travis Peak or Hosston. This resulted in 18,941 wells for which locations were available. After deleting the wells with obvious data problems, a total of 18,933 wells were used for the map. The data are provided as both lines and polygons, and the proprietary wells that penetrate the top of the Travis Peak or Hosston Formations are graphically displayed as quarter-mile cells.

This CD presents maps derived from a subset of the National Uranium Resource Evaluation(NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) data.Approxiamately 260,000 samples were analyzed in the continental U.S. and consisted ofsolid samples, including stream, lake, pond, spring, and playa sediments, and soils.Data for eleven elements were analyzed and included on this release of the NationalGeochemical Atlas CD: Na, Ti, Fe, Cu, Zn, As, Ce, Hf, Pb, Th, and U.The National Uranium Resource Evaluation (NURE) program of the Department of Energy (DOE) collecteda vast amount of chemical data on sediment, soil, and water samples from the United States in thelate 1970's and early 1980's. This element of the...
Cell maps for each oil and gas assessment unit were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in an assessment unit or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, dry, or the type of production of the wells located within the cell is unknown. The well information was initially retrieved from the IHS Energy Group, PI/Dwights PLUS Well Data on CD-ROM, which is a proprietary, commercial database containing information for most oil and gas wells in the...
![]() This CD-ROM contains a digital version of the Geologic Map of theUnited States, originally published at a scale of 1:2,500,000 (Kingand Beikman, 1974b). It excludes Alaska and Hawaii. In addition tothe graphical formats, the map key is included in ASCII text.A geographic information system (GIS) allows combining andoverlaying of layers for analysis of spatial relations not readilyapparent in the standard paper publication. This disc contains onlygeology. However, digital data on geology, geophysics, andgeochemistry can be combined to create useful derivative products--for example, see Phillips and others (1993).This CD-ROM contains a copy of the text and figures fromProfessional Paper 901 by King and Beikman (1974a)....
Debris flows, debris avalanches, mud flows and lahars arefast-moving landslides that occur in a wide variety of environmentsthroughout the world. They are particularly dangerous to life andproperty because they move quickly, destroy objects in their paths,and can strike with little warning. The purpose of this map is toshow where debris flows have occurred in the conterminous UnitedStates and where these slope movements might be expected in thefuture.

The Positive Structural Elements coverage maps, in the form of polygons, are known structural highs within the province that commonly define a basin proper or influence the occurrence of discovered or undiscovered hydrocarbon accumulations. Positive Structural Elements are shown here as geographic polygons that were only generally defined and mapped by the geologist responsible for the province. These Positive Structural Elements were mapped mostly from other resources, including previously published maps and literature (see Pollastro and Viger, 1998, in text portion of publication DDS-69-A). The Positive Structural Elements boundaries were defined in the period from March to May, 2000.
