For any particular lease, there may be commodity price information that is generated from severance tax information. In general, there may be Oil, Gas or both Oil & Gas commodities for any given lease (regardless of whether a lease is considered oil or gas).
The listing of prices and volumes is broken out by commodity and is listed by month and is available from the Price Data link that appears above a production chart.
Leases may have erratic reporting, therefore, there may not be data available for a specific month. See Severance Tax Reporting for more information.
