How to Value Mineral Rights in Texas

January 30, 2026 • 8 min read

Whether you have been approached by a mineral buyer, you are considering selling, or you just want to know what your minerals are worth, understanding mineral rights valuation is important. The value of minerals depends on several factors, and there is no single formula that works for every situation. Here are the primary methods and what drives the numbers.

Producing vs. Non-Producing Minerals

The first question is whether your minerals are currently generating royalty income:

• Producing minerals — There are active wells generating royalty payments. Valuation is based primarily on the income stream and remaining reserves.
• Non-producing minerals — No current production. Value depends on the likelihood and timing of future development (proximity to active drilling, operator interest, geology).

Income Approach (Producing Minerals)

The income approach is the most common method for valuing producing mineral interests. The basic process:

1. Determine current production — Monthly oil and gas volumes attributable to your interest. MineralSearch can help you check current production levels on your wells.
2. Apply decline curve — Project future production using decline curve analysis. This forecasts how production will decrease over time.
3. Apply price assumptions — Use current strip pricing or a flat price assumption for oil and gas.
4. Calculate your revenue — Multiply projected production by price by your net revenue interest (NRI).
5. Discount to present value — Apply a discount rate (typically 8-15% for mineral interests) to convert future cash flows to present value.

Rules of Thumb

Mineral buyers often use multiples of current monthly or annual income as a quick screen:

• Producing with long reserve life: 48-72x monthly income (4-6 years of income)
• Producing with shorter reserve life: 36-48x monthly income
• Declining production, older wells: 24-36x monthly income

These multiples vary significantly based on oil prices, basin, production decline rate, and remaining development potential.

Comparable Sales (Producing and Non-Producing)

Like real estate, mineral values can be estimated by looking at recent comparable transactions in the area. For non-producing minerals, this is often the primary method. Per-acre values vary dramatically:

• Core Permian Basin (non-producing): $5,000-$30,000+ per net mineral acre
• Eagle Ford core (non-producing): $5,000-$20,000 per net mineral acre
• North Texas conventional (non-producing): $500-$5,000 per net mineral acre
• Undeveloped, no nearby activity: $100-$1,000 per net mineral acre

These ranges are approximate and can change rapidly based on commodity prices and drilling activity.

Factors That Affect Value

• Location — Core Permian Basin minerals are worth multiples of minerals in less active areas
• Current production — Producing minerals with active wells are worth more than non-producing
• Remaining development potential — Are there undrilled locations? Multiple target zones?
• Lease terms — A 25% royalty is worth more than a 12.5% royalty on the same acreage
• Operator quality — Minerals operated by a well-capitalized operator are more valuable than minerals under a marginal operator
• Oil prices — Mineral values are highly correlated with commodity prices

Common Mistakes

• Accepting the first offer — Mineral buyers start low. The first offer is rarely the best offer.
• Ignoring decline curves — Assuming current production will continue indefinitely overvalues the minerals.
• Not checking comps — Selling without understanding what similar minerals have sold for in the area.
• Selling non-producing minerals before development — If an operator is about to drill, the minerals will be worth significantly more after a well proves up production.
