How can I determine if someone is operating on my royalty property? And or, stealing my mineral rights?
Welcome to the forum.
Wells are drilled on acreage which is owned by mineral owners. The operators do their best to determine who the owners are by title searches. They lease or pool the acreage depending upon the state and the regulations required. Each state with oil and gas drilling has an oil and gas commission which monitors activity.
If you want to give your state, county, section, township and range (or block, abstract name and number plus section number for TX), the forum can help point you in the right direction for where to find information.
