If you own mineral rights in an active basin, unsolicited offer letters arrive regularly. Some are detailed. Some are a single page. Some are addressed to your grandfather, who passed away in the 1990s. All of them are asking you to sell or lease your minerals, usually on a timeline.
Before responding to any of them, it helps to have a framework for reading them carefully. Here is a plain-English walkthrough of what to look for.
What the letter is actually proposing
Before you evaluate whether an offer is good, understand what the offer is.
Some letters propose to buy your minerals outright. This is an acquisition, a permanent transfer of your ownership in exchange for a one-time payment. You no longer own the minerals, and any future royalties, lease bonuses, or appreciation flow to the buyer.
Other letters propose to lease your minerals. This is not a sale. You retain ownership, and in exchange for a bonus payment and a royalty, the buyer (now acting as an operator or a lease broker) gets the right to develop during a primary term.
Still others propose to buy a partial interest, often a portion of the royalty or an overriding royalty interest, without acquiring the minerals themselves. These are less common but do appear.
The letter should make clear which of these is being proposed. If it is not clear, that is your first question to ask.
Who is on the other side
Offers typically come from one of three categories of counterparty.
Large established mineral acquisition companies. Reputable firms that do this professionally, close many transactions per year, and generally honor the terms they put in writing. Their initial offers may or may not be at the top of the market, but the transaction process tends to be predictable.
Smaller specialty buyers and brokers. Many of these are also reputable. Some are less so. Doing a quick search on the company name, looking for reviews, and asking for references is a reasonable first step when the name is one you do not recognize.
Individual landmen or intermediaries. Some offers come from individuals working on behalf of a buyer they do not identify until later in the process. This is not necessarily a problem, but it is worth knowing.
If you cannot tell who you are dealing with from the letter itself, that is itself useful information.
The price, and what it is compared to
The number in the letter is usually the first thing you notice. It is also often the least important factor in figuring out whether the offer is reasonable.
The question is not what the number is, it is what the number is relative to what your tract is actually worth. An offer that sounds substantial in isolation might be well below a tract-specific valuation. An offer that sounds modest might actually be fair, if the tract is not in an especially active area.
This is why a separate valuation, done by someone who does not stand to gain from either direction, is useful before responding. Even a rough one helps you calibrate.
Terms buried in the fine print
This is where offers often differ more than the top-line price suggests.
The closing terms
When is the payment actually made? What happens if the closing is delayed? Is the payment contingent on anything, like title confirmation or the buyer’s own internal approvals?
Title and due diligence provisions
Most offers include some form of title contingency. The buyer wants to confirm you actually own what you are selling before they pay. This is reasonable, but the specific language matters. Some contingencies are easy to satisfy. Others give the buyer broad discretion to walk away or reduce the price based on minor title issues.
The specific property description
What exactly are you selling? All of your minerals in a given tract, or only a portion? All depths, or only certain formations? Is the description accurate and complete?
This is a place where small ambiguities can become expensive disputes later.
Reservations and carve-outs
Does the offer include any specific reservations, such as retaining an overriding royalty interest or a portion of future bonus payments? Any offer that is less than a total conveyance has specific terms worth understanding.
Special indemnities, warranties, and representations
What are you promising the buyer about the minerals and their condition? What is the buyer promising you? These sections are typically written in legal register and deserve a careful read or a review by an attorney.
Questions worth asking before responding
If you are considering the offer seriously, a few questions are worth asking the buyer directly.
Who is the end buyer? Are you a broker or the acquiring party? How does your due diligence process work, and what is a typical timeline from offer acceptance to closing? What happens if title issues come up during your review? Have you bought mineral interests in this specific area before, and if so, would you be willing to share general context?
The answers to these questions tell you a great deal about what kind of counterparty you are dealing with, separate from whatever the letter says.
What to do if the offer is the first you have received
A few general guidelines.
Do not sign anything before having someone review it. An attorney who works with oil and gas transactions, or a trusted mineral rights professional, can save you a great deal in either direction. Their fees are almost always a small fraction of the difference between a well-negotiated offer and a poorly-negotiated one.
Do not respond to the letter with your minerals’ chain of title, deeds, or other documentation beyond what is necessary. The letter is from someone trying to buy from you, which is a negotiation. Share information deliberately.
If the letter has you thinking about selling more broadly, it is also worth understanding the kind of company on the other end. Our guide on choosing a buyer covers the difference between a broker and a direct buyer and what to look for in whoever you sell to.

If you received an offer recently and you are trying to figure out how to respond, we are happy to walk through it with you. No obligation, no pressure. We do this every day, and a short conversation often clarifies whether the offer is in a reasonable range, whether the terms are standard, and what questions are worth asking the buyer before deciding anything.
