Every operator on file with the regulators in Oklahoma, Texas, Kansas, Colorado, and Wyoming, searchable in your browser. Start typing a company name or operator number.
The phone numbers in this directory belong to the operators, not to Berlin Royalties.
We publish these records as a free public reference. We are a mineral buyer in Tulsa and we are not affiliated with any operator listed here, so we cannot look up your account, your check, or your division order with them. Call the operator's own number to reach the operator.
The number in our menu and footer, and in the bar at the bottom of your screen on a phone, rings Berlin Royalties. If you want a free second opinion on a royalty problem, that is exactly the right number. It is not the operator's.
We buy minerals and royalties for our own account and show you the valuation math beside the offer. Fastest route: text a photo of your check stub to 918-984-1645 and we will tell you what it says and what the interest is worth. Free either way. Or start here:
The operator is the company that drills and runs the well, sends your division order, and cuts your royalty check. Its name appears on your check stub, your division order, and any pooling paperwork. Search the name or operator number above and you get the address, phone number, and, in Oklahoma, the contact person the operator registered with the state, which is usually the fastest way to reach a live human about a suspended check or a wrong address.
Because the states do not publish them. Oklahoma's guidance is to call the operator at the number listed and ask for the email you need, and the other states are the same. When you call, ask specifically for owner relations or the division order department. That is the group that handles royalty owner questions, and asking for it by name saves a transfer or three.
Operators register with the state to do business there. Active means the registration is current. Closed, inactive, or expired usually means the company stopped operating, was sold, merged, or let its filing lapse, which is common for the older names on legacy wells. Untick the active box to search those too, which is what you want when tracing an old check stub or a well that changed hands decades ago.
Wells change hands constantly, and the company paying today may be three sales removed from the name you remember. Search the old name here with the active filter off, then look up the well itself in that state's well records to see who operates it now. If the trail goes cold, or you suspect royalties are sitting in suspense under a relative's name, our page on finding unclaimed royalties covers where that money hides, and you can always just ask us. We trace operators for a living and will do it for you free.

The differences come from the states, not from us: each regulator publishes a different slice of its operator file, and we show exactly what each one makes public. New Mexico, North Dakota, Louisiana, and Arkansas do not publish a free operator directory with contact information, so they are not here yet. If you need an operator in one of those states, ask us and we will look it up.
For the operators that account for most of the drilling and most of the producing wells across the states where we buy, we publish a page each: producing well counts and wells spudded in the last 24 months by state, registered regulator contact information where the state publishes it, and what to do if your check from them is late or wrong. Sourced from Enverus, current as of 2026-08.
Do not see yours? The searchable directory above covers more than 38,000 operators across five states, and we will look up any operator in any state free through Ask a Landman.
Usually the operator search is step one toward a bigger question: is my check right, what are my minerals worth, or should I sell? Our free calculators check your decimal and estimate your check, and a free valuation gives you a real number with the work shown, whether or not you ever sell.

Berlin refreshes this copy weekly; last updated 2026-09-28, covering 38123 operators. We reformat the states' data for readability and do not alter it. Errors in a state's record will appear here too; tell us if you spot one. Kansas asks that its licensee list not be used for commercial solicitation, and we do not use it that way.
