There are hundreds of pre-made charts in the USOGRS system that show oil and gas data at three levels of aggregation. One set of charts shows the distribution of province or basin-level variables (e.g., the probability distribution of undiscovered oil in a basin). The second set compares variables by play within a single basin (e.g., the average size of oil fields by play within a basin). The third set of charts details a specific play (e.g., the discovery history of fields within a single play).

Clicking on each of the chart links will show you a chart description and an example chart.
