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 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,...
