Summary

Description

The Total Petroleum System is used in the National Assessment Project and incorporates the Assessment Unit, which is the fundamental geologic unit used for the assessment of undiscovered oil and gas resources. The Total Petroleum System is shown here as a geographic boundary defined and mapped by the geologist responsible for the province and incorporates not only the set of known or postulated oil and (or) gas accumulations, but also the geologic interpretation of the essential elements and processes within the petroleum system that relate to source, generation, migration, accumulation, and trapping of the discovered and undiscovered petroleum resource(s).

Summary

Description

These are shapefiles and coverages of data points used in the assessment of coal zones A, B, C, and D in the Yampa coal field, northwestern Colorado. There are four separate shapefiles, one for coal zone. Yama_pts is for the A coal zone, yamb_pts is for the B coal zone, etc.

Summary

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 (lm1thicklg.shp and lm1thickpg.shp), and the public wells that penetrate the entire thickness of the Lower Miocene 1 sequence are provided in a point shapefile (lm1thickptg.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.

The Total Petroleum System is used in the National Assessment Project and incorporates the Assessment Unit, which is the fundamental geologic unit used for the assessment of undiscovered oil and gas resources. The Total Petroleum System is shown here as a geographic boundary defined and mapped by the geologist responsible for the province, and incorporates not only the set of known or postulated oil and (or) gas accumulations, but also the geologic interpretation of the essential elements and processes within the petroleum system that relate to source, generation, migration, accumulation, and trapping of the discovered and undiscovered petroleum resource(s).

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.

This is a shapefile and coverage of data points used in the assessment of coal resources of the Fruitland Formation in the San Juan Basin, Colorado and New Mexico. Data in this file include a point identifier, x, y, location; surface elevation of the drill hole; elevations for the top of the uppermost coal and for the base of the lowermost coal; net coal thickness of coal beds greater than or equal to 1.2 ft; and number of beds comprising the net coal thickness.

Summary

Description

A geographic information system focusing on the Upper Cretaceous Taylor and Navarro Groups was developed for the U.S. Geological Survey's (USGS) 2003 assessment of undiscovered, technically recoverable oil and natural gas resources in the Gulf Coast Region. The USGS Energy Resources Science Center has developed map and metadata services to deliver the 2003 assessment results GIS data and services online. The Gulf Coast assessment is based on geologic elements of a total petroleum system (TPS) as described in Condon and Dyman (2005). The estimates of undiscovered oil and gas resources are within assessment units (AUs). The hydrocarbon assessment units include the assessment results as attributes within the AU polygon feature class (in geodatabase and shapefile format). Quarter-mile cells of the land surface that include single or multiple wells were created by the USGS to illustrate the degree of exploration and the type and distribution of production for each assessment unit. Other data that are available in the map documents and services include the TPS and USGS province boundaries.

Summary

Description

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.

Summary

Description

This dataset represents lineaments in the Powder River Basin as identified in the following publication: Maughan, E.K., and Perry, W.J., Jr., 1986, Lineaments and their tectonic implications in the Rocky Mountains and adjacent plains region: in Peterson, J.A., ed, Paleotectonics and Sedimentation in the Rocky Mountain Region, United States: American Association of Petroleum Geologists Memoir 41, pp. 41-56. A lineament is defined as a linear topographic feature of regional extent that is believed to reflect crustal structure (Hobbs et al., 1976, p. 267). Lineament features were transferred from the publication to a hard-copy base map by province geologist, then digitized and referenced for use in a Geographic Information System (GIS). Lineaments may: 1) enhance secondary reservoir permeability and 2) provide migration pathways in unconventional rocks.
