Summary

Description

The drilling history documents oil and gas wells in the Upper Miocene sequence as a whole and in 10-year intervals. The wells included in this interval are determined by completion date and by comparing the depth of the wells to structure contours of the Upper Miocene sequence. The data are provided in a single file (um_prod.shp) as well as eight 10-year interval files covering 1920 through 1999. 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.

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.

Summary

Description

This shapefile includes arcs and polygons that describe U.S. Geological Survey delineated Total Petroleum Systems of the World. Each petroleum system is defined as a mappable entity encompassing genetically related petroleum that occurs in seeps, shows and accumulations (discovered or undiscovered) that have been generated by a pod, or by closely related pods, of mature source rock, together with the essental mappable geologic elements (source, reservoir, seal and overburden rocks) that control fundamental processes of generation, migration, entrapment and preservation of petroleum. Total petroleum systems are described by U.S. Geological Survey scientists on the basis of exploration and production histories, and extensive literature searches. Total petroleum systems are identified with a numeric code derived from the numeric code of the World Geologic Provinces as defined by the U.S. Geological Survey World Energy Project. Most total petroleum systems are contained within a single geologic province, but there are numerous cases where systems span more than one province. Summary results of the assessment are presented as attributes of this shapefile.

Summary

Description

A geographic information system focusing on Tertiary strata and Cretaceous-Tertiary coalbed gas was developed for the U.S. Geological Survey's (USGS) 2007 assessment of undiscovered, technically recoverable oil and natural gas resources of the Gulf Coast Region. The USGS Energy Resources Science Center has developed map and metadata services to deliver the 2007 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 Dubiel and others (2007) and Warwick and others (2007). The estimates of undiscovered conventional oil and gas resources are within 33 assessment units (AUs) and the estimates of continuous coalbed gas resources are within 4 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, as well as Claiborne Group structure and isopach maps.

This map document contains oil and gas assessment units and cells that were defined for the 2010 assessment of undiscovered oil and gas resources in Jurassic and Cretaceous strata of the Gulf Coast. Using a geology-based assessment methodology, the U.S. Geological Survey estimated means of 147.4 trillion cubic feet of undiscovered natural gas, 2.4 billion barrels of undiscovered oil, and 2.96 billion barrels of undiscovered natural gas liquids in Jurassic and Cretaceous strata in onshore lands and State waters of the Gulf Coast.

Summary

Description

These are shapefiles and polygon coverages that contain numerous attributes of information on coal in the Calico and A-sequences of the Upper Cretaceous Straight Cliffs Formation in the Kaiparowits Plateau study area in southern Utah. These layers were derived from a "union" process of combining numerous polygon coverages using the Environmental Systems Research Institute, Inc. (ESRI) Arc/Info UNION command, and finally calculating coal tonnage in INFO. Net coal thickness values are from 209 data points and represent all coal beds that are more than 1 foot thick. The outside polygon defines the base of the coal-bearing Calico and A-sequences east of 112 degrees of longitude. The northern boundary is delineated by the Paunsaugunt fault and basal outcrops of volcanic rocks of Tertiary age.

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

This is a polygon coverage that represents areas underlain by the coal-bearing Calico and A-sequences of the Straight Cliffs Formation east of 112 degrees of longitude. It differentiates between areas that contain the entire coal-bearing interval and areas where the coal-bearing strata are partially eroded. The outermost polygon defines the base of the Calico and A-sequences. The inner polygon shows where the complete coal-bearing interval is preserved. The area between the outer and inner polygon shows where the coal-bearing rocks are partially eroded. The northern boundary is delineated by the Paunsaugunt fault and volcanic rocks of Tertiary age.

Summary

Description

This dataset is a polygon coverage of the Fire Clay coal zone that represents the areas in which resources were calculated and is only part of the full outcrop of the coal zone. Parts of the boundaries of the resource areas represent the 14-inch thickness isoline of the Fre Clay coal or the sub-crop limits of data availability; other parts of the boundaries are actual outcrop. The file has been generalized from detailed geologic coverages found elsewhere in Professional Paper 1625-C. This resource model for the Fire Clay coal zone must be considered provisional, because the correlation of the zone continues to be evaluated in West Virginia.
