Some of you might find the following site interesting especially if you don’t live near where your mineral rights are. http://gis.deq.ok.gov/flexviewer/
You can open the link and then zoom into the area you are interested in then check the box next the Tier II Hazardous Substances. Each of the icons that appear on the map represents a facility that stores hazardous substances (such as crude oil). If you click on the icon it will give you a facility name (in the case of a production site it will give you the name of the operator and the name of the well).
Facilities that store chemicals are required under the Emergency Planning and Community Right-to-Know Act (EPCRA) to submit an Emergency and Hazardous Chemical Inventory Form to the Local Emergency Planning Committee (LEPC), the State Emergency Response Commission (SERC), and the local fire department annually.
In the area we are interested in most of the icons represent a producing well. By the way you can also click next to Section Township Range on the layer list and help you find your site.
