Sourced from Enverus and current as of 2026-08. | State | Producing wells | Spudded, last 24 months | Your state's rules | | **Kansas** | 92 | 17 | [Kansas mineral owner guide](https://www.berlinroyalties.com/kansas/) || **Colorado** | 168 | - | [Colorado mineral owner guide](https://www.berlinroyalties.com/colorado/) | ## Contact information on file with state regulators These are the addresses and phone numbers MULL DRILLING COMPANY has registered with each state's oil and gas regulator. Regulator records are the most reliable public contact path for an operator, and they are frequently more current than what is printed on a check stub. Refreshed weekly from each agency's public file. | State | Regulator ID | Address | Phone | | WY | | | - || CO | 61250 | MULL DRILLING COMPANY INC, Wichita, KS 67206-6637 | - || KS | 5144 | 1700 N WATERFRONT PKWY BLDG 1200, Wichita, Ks 67206 | (316) 264-6366 | A registered agent address is not always the owner relations department. If the number above is a corporate switchboard, ask for owner relations or division order, and have your owner number ready. ## If your check is late, wrong, or stopped The remedies here are statutory in most states, and most owners never use them. Work in this order. - **Send a written demand by certified mail**, return receipt requested, with your owner number on it, and keep it to a single request. Most state royalty payment statutes and most contractual notice provisions require written demand before anything else becomes available, and the receipt establishes the date. Our [free letter templates](https://www.berlinroyalties.com/letter-templates/) include ready to send versions. - **Check what your state's statute actually gives you.** Most producing states impose a payment deadline and automatic late payment interest. Our [royalty payment laws by state](https://www.berlinroyalties.com/royalty-payment-laws/) page has the deadline, the interest rate, the minimum threshold, and the limitation period, each with its statute citation, including Kansas. - **Read the deductions against your state's rule.** Whether post production costs may be taken at all varies sharply by state, and a deduction that is routine in one state is a violation in another. Our [statement decoder](https://www.berlinroyalties.com/royalty-statement-decoder/) explains every line on the stub. - **Escalate.** Our [complaints and disputes page](https://www.berlinroyalties.com/mineral-complaints/) sets out which forum handles which problem, in the order that actually produces results. ## Common questions about MULL DRILLING COMPANY My royalty check from MULL DRILLING COMPANY stopped. What happened?The most common causes, in order: a title or ownership change that put your interest in suspense, an unprobated death in the chain, an address the operator could not deliver to, a balance under the state's minimum payment threshold so it is being held until it accumulates, or a change of payor after an acquisition. Payor changes are especially common right now across several basins, and owners frequently believe a royalty has stopped when it has only moved to a new company. Send us the last statement you received and we will tell you which of these it is, free. How do I know whether my decimal is correct?Compare the decimal on your check stub against your division order, and against your own arithmetic: net mineral acres divided by unit acres, times your royalty rate, times any depth or formation allocation. Our free calculators run that math. If it does not reconcile, request the unit's allocation factor and the recorded pooling or unitization order in writing. Decimal errors are usually clerical rather than deliberate, and operators generally correct them and pay the arrears once shown the arithmetic. Can I sell my interest even though MULL DRILLING COMPANY operates the wells?Yes. You own the mineral or royalty interest; the operator holds the lease and runs the wells. You can convey your interest without the operator's consent or involvement. After closing, the buyer files a transfer order and the operator redirects payment. Nothing about the operator's identity restricts your ability to sell, and you can also sell only part of what you own. I own interests under MULL DRILLING COMPANY in more than one state. Is that one transaction?It can be. We regularly buy interests spanning several states in a single closing with one deed package, which saves the seller a great deal of paperwork. It matters more than it sounds, because the law differs by state: post production cost rules, severance rates, nonresident withholding, and whether minerals can lapse for nonuse all change at the state line. We value each state's interest on its own terms and show you the components rather than blending them into one number. ### Own minerals MULL DRILLING COMPANY operates? Find out what they are worth. Send a check stub or a division order. We will identify the interest, tell you what the wells and any remaining locations support, show you the reasoning, and tell you honestly if you should keep it. Free, no obligation, and no mailing list. We will also tell you if we think something on your statement is wrong.
