Summary
Description
Cell maps for each oil and gas assessment unit were created by the USGS to illustrate 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 U.S. Cells were developed as a graphic solution to overcome the problem of displaying proprietary PI/Dwights PLUS Well Data. No proprietary data are displayed or included in the cell maps. The data from PI/Dwights PLUS Well Data were current as of 2003 when the cell maps were created in 2006.

Summary
Description
A large percentage of the present and future energy resources of the United States reside in the Gulf of Mexico Basin, one of the major hydrocarbon producing areas of the world. Recent conceptual and technological advances have resulted in significant new finds and opened large areas to new or renewed exploration. The U.S. Geological Survey's Framework Studies and Assessment of the Gulf Coast Project was established in 1999 to provide the geologic, geophysical, and geochemical framework studies that will aid in a reassessment of energy commodities (coal, gas, and oil) in the Gulf Coast Region. The project targets intervals identified during preceding oil, gas, and coal assessments as requiring additional study. It (1) defines the petroleum systems of the region; (2) conducts specific geologic framework studies and petroleum system analyses on selected priority intervals; (3) studies the coal-bearing interval to evaluate coal distribution and quality, coal-bed gas, and source rock potential; (4) works in cooperation with the National Oil and Gas Assessment (NOGA) Project to conduct a focused assessment of the Gulf Region; and (5) contributes to the next phase of the National Coal Resource Assessment. Gulf Coast Geology (GCG) Online is a Geographical Information System (GIS) database, developed as an ArcMap (ESRI, 2003) project to be served online utilizing ArcIMS (Internet Map Service, ESRI, 2003) It serves three major needs of the project: 1) efficient, centralized data management and visualization; 2) development and sharing of data and interpretations by project personnel; and 3) dissemination of information and products to customers in an easily usable format. Currently, all USGS assessments are petroleum system based and require large amounts of geologic, geophysical, geochemical, and paleontologic data in addition to well and field databases. In mature provinces and especially in large ones such as the Gulf Coast these data sets can be quite large so the data management role becomes critical. For example, the Miocene database alone contains nearly 100 layers in addition to the 25 layers of geographic and geologic bases. At the same time, it is necessary for the large number of scientists working under tight deadlines on a wide variety of topics to have ready access to all of these data as well as to each other's most recently developed data and interpretations. An additional requirement is that the output be easily usable by project personnel or customers (management, other scientists, the general public, etc.) who may or may not have any GIS expertise or very sophisticated equipment. This is particularly important for government agencies such as the USGS whose primary mission is to provide the best and most current information possible to decision makers and the public. The USGS will publish DS 90 in a series of releases that will be made available online as they are completed. DS 90-A will pertain to the Miocene only while DS 90-B, C, etc. will pertain to other parts of the section or other formations. Each release will have a version number so that updates may be tracked and referenced. DS 90-A, version 1 for example, deals almost exclusively with the Miocene of southern Louisiana, primarily because of the availability of data. Sources of data specific to each individual layer within the database are documented in the metadata for that layer. In most cases, the accuracy of data from outside sources is assumed to be sufficient for the purposes of this regional compilation and the user is cautioned in the use of these data at prospect and smaller scales. All data are in the form of shapefiles except for the base cartographic layers, which are ArcSDE (Spatial Data Engine, ESRI, 2003) layers and maintained on the U.S. Geological Survey Central Energy Resources Team server along with the applications software. An updated version, DS 90-A, version 2, perhaps combining data on the Miocene of Texas with the previously published data, will be published at a later date. All versions of all releases will be available through the Central Energy Resources web site at http://energy.cr.usgs.gov/.

Summary
Description
Worldwide coal consumption and international coal trade are projected to increase in the next several decades (Energy Information Administration, 2007). A search of existing literature indicates that in the Western Hemisphere, coal resources are known to occur in about 30 countries. The need exists to be able to depict these areas in a digital format for use in Geographic Information System (GIS) applications at small scales (large areas) and in visual presentations. Existing surficial geology GIS layers of the appropriate geologic age have been used as an approximation to depict the extent of coal-bearing areas in North, Central, and South America, as well as Greenland. Global surficial geology GIS data were created by the U.S. Geological Survey (USGS) for use in world petroleum assessments (Hearn and others, 2003). These USGS publications served as the major sources for the selection and creation of polygons to represent coal-bearing areas. Additional publications and maps by various countries and agencies were also used as sources of coal locations. GIS geologic polygons were truncated where literature or hardcopy maps did not indicate the presence of coal. The depicted areas are not adequate for use in coal resource calculations, as they were not adjusted for geologic structure and do not include coal at depth. Additionally, some coal areas in Central America could not be represented by the mapped surficial geology and are shown only as points based on descriptions or depictions from scientific publications or available maps. The provided GIS files are intended to serve as a backdrop for display of coal information. Three attributes of the coal that are represented by the polygons or points include geologic age (or range of ages), published rank (or range of ranks), and information source (published sources for age, rank, or physical location, or GIS geology base).

Summary
Description
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 elements that define the Assessment Unit, such as limits of reservoir rock, geologic structures, source rock, and seal lithologies. The only exceptions to this are Assessment Units that border the Federal-State water boundary. In these cases, the Federal-State water boundary forms part of the Assessment Unit boundary.

Description
The thickness contours were created using biostratigraphic data in the Paleo-Data, Inc., Tenroc Regional Geologic Database. The depths of the microfossil locations were associated with the wells data provided by the Louisiana Department of Natural Resources. Because of the proprietary nature of the Tenroc database, no actual data can be shown and only those data points contained in the Louisiana State wells database are included in the control points layer. Contouring was accomplished in Dynamic Graphics, Inc., EarthVision modeling software (v.5) using minimum tension gridding. Three custom programs were used to convert contour lines generated from grids in EarthVision to Arc/Info coverages and then to shapefiles. The data are provided as both lines and polygons (lm2thicklg.shp and lm2thickpg.shp), and the public wells that penetrate the entire thickness of the Lower Miocene 2 sequence are provided in a point shapefile (lm2thickptg.shp). These datasets contain basic data and interpretations developed and compiled by the U.S. Geological Survey's Framework Studies and Assessment of the Gulf Coast Project. Other major sources of data include publicly available information from state agencies as well as publications of the U.S. Geological Survey and other scientific organizations. In cases where company proprietary data were used to produce various derivatives such as contour surfaces, the source is cited but the data are not displayed.
