Working Interests

A working interest gets paid more per barrel than a royalty, and it also gets billed for the well's costs, and pricing one without both halves of that equation gets the number wrong.

A working interest is an ownership stake in the oil and gas lease itself, carrying the right to a share of production but also the obligation to pay a proportionate share of drilling, completion, and ongoing operating costs. That's fundamentally different from a royalty interest, which receives production revenue free of those costs. Working interests appear in mineral portfolios in a few common ways: an owner who negotiated a working interest instead of a straight royalty when leasing, a nonoperated working interest inherited or purchased, or a landowner who participated financially in a well on their own acreage.

Net Revenue Interest Is the Real Number

A working interest's actual economic value flows through its net revenue interest, the share of production revenue remaining after royalty burdens on the lease are paid out, further net of the owner's proportionate share of operating expenses. Two working interests with identical gross percentages can have meaningfully different value if one carries a heavier royalty burden or higher lease operating costs than the other, so any valuation has to work from net figures, not the headline working interest percentage alone.

Operating Costs Cut Into Every Check

Unlike a royalty owner, a working interest holder receives revenue statements net of their share of lease operating expenses, transportation, processing, water disposal, workover costs, and more, which means monthly checks can shrink meaningfully during a costly maintenance stretch or even go negative in a low-price, high-cost month on some wells. A valuation has to account for this cost exposure directly, typically by applying a multiple to net-of-cost cash flow rather than gross revenue, and by weighing whether the specific well or wells have a history of unusually high operating costs.

Nonoperated vs Operated Positions

Most individual working interest owners hold a nonoperated position, meaning another company runs day-to-day operations and the owner simply receives their proportionate share of revenue and bills for costs without decision-making control over the well. That lack of operational control is a real factor in valuation, since a nonoperated owner can't influence decisions like workover timing or additional drilling that affect future cash flow, and a buyer's valuation should reflect that reduced control relative to an operated position.

Why Working Interest Comps Don't Match Royalty Comps

Because a working interest carries cost exposure a royalty never does, its multiple is calculated against a different, cost-adjusted cash flow base and generally isn't directly comparable to a royalty multiple on the same well, even though both are described using a similar-sounding percentage. An owner comparing a working interest offer against a royalty valuation they've seen elsewhere, on their own acreage or a neighbor's, is comparing two different economic instruments, and the comparison won't hold up without adjusting for the cost side of the ledger.

Well-Level Cost History Matters More Than Basin Reputation

Two wells in the same basin, even the same section, can carry different operating cost profiles depending on age, mechanical condition, and how much water or other byproduct they produce alongside oil and gas, and lifting costs generally climb as a well ages and its water cut increases. A careful working interest valuation reviews actual joint interest billing history for the specific well, not a generic basin-level cost assumption, since that history is the clearest signal of what future net revenue is likely to look like.

Owners considering a sale should ask to see recent joint interest billing statements alongside revenue statements, since the cost side of the ledger tells as much of the valuation story as the revenue side does for this interest type, and skipping that review is the fastest way to overpay or underprice a working interest.
