USGS National Assessment of Oil and Gas Project - Unconventional Assessment Units from 2000 to 2011 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 herein 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 coal field outlines are approximate boundaries based on criteria provided below under Data Quality Information, Process Steps. These coal field outlines may not overlap exactly with other published coal field boundaries or with criteria used in the geochemistry data. We used existing polygons taken from numerous digital geologic maps, as described in Process Steps, but did not use overburden cutoffs.
