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...

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).

The collection of LiDAR data for the James River basin began in 2010. The detailed surface elevation data will be used for conservation planning, design, research, delivery, floodplain mapping and hydrologic modeling utilizing LiDAR technology. The project area includes part of the James River watershed and adjacent areas in North and South Dakota. The project encompasses 16,825 sq miles and the 2010 phase of the project acquired 8,060 sq miles of LiDAR data and subsequent terrain data. This project represents the second phase with an objective to collect the remaining 8,765 square miles of the project area.

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, Total Petroleum Systems are defined and Assessment Units are defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes. The Williston Basin Province is located in North Dakota, eastern Montana, and northwestern South Dakota, encompassing all or parts of Divide, Burke, Renville, Bottineau, Rolette, Towner, Cavalier, Pembina, Walsh, Grand Forks, Nelson, Ramsey, Benson, Eddy, Foster, Wells, Griggs, Steele, Traill, Cass, Barnes, Ransom, Richland, Sergeant,...
