Are Things Falling Through the Cracks?

Why Mineral, Royalty, and Working Interest Portfolios Need Professional Management

The most common concern we hear from mineral, royalty, and working interest owners is not about commodity prices, drilling activity, or whether to sell. It is a quieter worry, and it usually gets phrased almost exactly the same way: “I think things are falling through the cracks.”

That instinct is generally correct. Not because owners are careless, and not because operators are dishonest, but because the system that produces a royalty check is built for the operator’s convenience, runs on information the owner never sees, and fails silently when something goes wrong. Nobody sends a letter explaining that you were left off a pay deck.

This article covers why that happens, what specifically gets lost, and what a professionally managed portfolio does differently. It is the first in a series on mineral ownership; the later articles go deeper on mineral rights generally, inherited interests, and division orders.

Permit to Pay: What It Actually Takes

Consider the basic task of tracking a single well from permit to first payment.

A permit is filed. A spacing or pooling application may follow, with election deadlines attached. The well is drilled, completed, and an as-drilled survey establishes where the lateral actually went. First sales occur. A title opinion is prepared or updated. Ownership is entered into a pay deck. A division order is issued and returned. Only then does a check appear.

That sequence requires input from at least four disciplines that rarely sit in the same room: land and title, division order analysis, GIS and mapping, and revenue accounting. It routinely takes months. Statute sets the outside boundary rather than the pace, and even the boundaries are generous: Texas allows 120 days after the end of the month of first sale for the first payment, and Oklahoma allows six months.

Now multiply. A typical portfolio has dozens or hundreds of wells somewhere in that pipeline at any moment, spread across multiple operators, counties, and states. Keeping up means spreadsheets, emails, phone calls, portal logins, and a surprising volume of physical mail, with each thread advancing on its own schedule. It is not difficult to see how items drop.

Why Owners Cannot Realistically Catch This Themselves

This is not a comment on anyone’s intelligence or diligence. It is a structural problem, and it has five parts.

You cannot audit what you are not shown. Your royalty decimal is derived from a title opinion you will never receive, applied to a unit allocation you did not participate in, against production volumes you did not measure. The check detail shows conclusions, not inputs.

The asymmetry is enormous. On the other side of every statement is an operator with land, division order, revenue accounting, GIS, regulatory, and legal departments, running purpose-built software. On your side is a folder and a memory of what your father told you.

The failure mode is silence. Missing revenue does not generate an error message. A well drilled on a tract that never made it into your inventory simply never appears. An interest sitting in suspense produces no mail. The absence of a problem and the absence of information look identical from a mailbox, and a tract sitting correctly in your inventory is no protection: the well can be drilled, produced, and sold for years while the revenue never finds you.

The complexity increased and nobody sent notice. Multi-section horizontal units, allocation wells, increased-density drilling, amended pooling orders, and a decade of operator consolidation have all made ownership harder to track. Every acquisition rebuilds a pay deck, and every pay-deck migration is an opportunity for an interest to be dropped, duplicated, or misapplied.

The deadlines run against you, quietly. Pooling elections in Oklahoma commonly expire twenty days from the order. Contractual audit rights on joint interest billings are frequently limited to twenty-four months after the year in which charges were billed. Claims for underpayment are subject to limitations periods. Unclaimed funds escheat after roughly three years in Texas and five in Oklahoma. None of these clocks send reminders.

Nobody ever bought a mineral interest hoping it would never get developed. But development is exactly when the administrative burden arrives, and it arrives all at once.

What Actually Falls Through the Cracks

In practice, the losses cluster into a short and repetitive list. Nearly every portfolio we review contains at least one of these, and larger portfolios usually contain several.

Wells producing on acreage that was never in the owner’s inventory in the first place
Wells producing on acreage the owner does know about, where revenue simply never started: a different operator than the one the owner deals with, a division order never returned, curative never supplied, an ownership change never reported, or a check going to an address from three moves ago
Interests that were never leased, or pooling elections that expired unanswered
Revenue sitting in operator suspense pending title curative nobody was told about
Funds already escheated to a state unclaimed property division, or held in a state regulatory escrow account following a forced pooling order
Incorrect decimals, including misapplied overriding and non-participating royalty burdens
New wells added to an existing unit that never made it onto the owner’s statement
Post-production deductions inconsistent with the governing lease language
Statutory interest owed on late or suspended payments and never demanded
Joint interest billing errors on non-operated working interests: overhead rates, AFE overruns, non-consent penalty calculations, and charges outside the accounting procedure
Lease expirations that passed without anyone noticing the renegotiation opportunity
Deceased owners still on pay decks, and returned mail that quietly converted an active account into an inactive one

Individually, most of these look like paperwork. Collectively, over a producing life measured in decades, they are the difference between what a portfolio yields and what it is capable of yielding.

The Recovery Is Not Just the Principal

When late or suspended payments are identified and pursued, the statutory interest is frequently a meaningful portion of the recovery. The rates are not nominal.

State	When Payment Is Due	Interest on Late Payment
Oklahoma	Not later than six months after the date of first sale, then by the last day of the second succeeding month, with a longer track for gas proceeds remitted to the operator.	12% per annum compounded annually, or a reduced rate where the delay is caused by unmarketable title.
Texas	On or before 120 days after the end of the month of first sale, then roughly 60 days for oil and 90 days for gas, subject to the lease.	Two percentage points above the rate charged on loans to depository institutions by the New York Federal Reserve Bank, unless the lease specifies otherwise.
North Dakota	Within 150 days after production is marketed.	18% per annum, applied as simple interest.

Texas also gives a payee a written-notice mechanism: after notice of nonpayment, the payor must pay or explain in writing within thirty days. Oklahoma treats suspended proceeds as accruing interest while title is being cleared. These are real entitlements, and they overwhelmingly go unclaimed, because claiming them requires knowing a payment was late in the first place.

Value Expires

The reason this is urgent rather than merely important is that the recoverable window closes on its own.

Contractual audit rights on joint interest billings commonly lapse twenty-four months after the end of the year in which the charges were billed
Underpayment claims are subject to state limitations periods
Unclaimed proceeds escheat to the state, and in Oklahoma proceeds abandoned for fifteen years can expose the underlying mineral interest itself to judicial sale
Several states, North Dakota among them, have dormant mineral statutes under which an unused severed interest can vest in the surface owner
Pooling elections expire in days, not months

Every year a portfolio goes unexamined, some portion of what could have been recovered stops being recoverable.

What We Do Differently: Gold Mining

Most mineral management is, at bottom, processing. Revenue arrives, it is booked, it is reported, and a statement goes out at the end of the year. That work is necessary and we do it well. It is also the easy half, because it only handles money the operator has already decided to send you.

Our primary focus is the other half. We call it gold mining, and it starts from the asset rather than the check.

Rebuild and perfect the land asset inventory. Every tract, legal description, net mineral acre, interest type, burden, lease, and unit, verified against the record rather than inherited from a spreadsheet. This is the step almost everyone skips, and it is the step that determines whether anything else can be checked. You cannot notice a missing well on acreage you do not know you own.
Reconcile the inventory against production and revenue data. Regulatory production records, unit designations, pooling orders, and check detail are pulled into the same view and compared. Wells that should be paying and are not become visible at that point, and only at that point. That includes wells on tracts the owner knows perfectly well that they own, where a curative gap, an unreturned division order, an unreported ownership change, an unfamiliar operator, or a stale address quietly kept the revenue from ever starting.
Apply forensic accounting to the check detail. Volumes against reported production. Realized prices against benchmarks. Deduction categories against actual lease language. Decimals across time to catch drift. Payment months against production months to find gaps. Property numbers that appear once and never again.
Investigate and recover. Suspense balances, escheated funds, state escrow accounts from pooling orders, unbilled and misallocated revenue, statutory interest, and joint interest billing exceptions, pursued with the curative and documentation each requires.
Monitor going forward. New permits, spacing and pooling applications, completions, unit amendments, operator changes, and lease expirations tracked against the inventory so the next opportunity is caught on schedule instead of years later.

The disciplines that make this possible are the same ones the operator uses, brought together under one roof: land and title, division order analysis, GIS, revenue accounting, and regulatory data analysis. What makes the approach different is the order of operations. Most managers start with the revenue and work outward. We start with the asset and work toward the revenue, on the assumption that the gap between the two is where the value is.

It is unglamorous work. It is also where the money that nobody is looking for turns out to be.

The Honest Version of the Pitch

Professional management is not magic, and no one can promise a recovery on a specific portfolio before looking at it. Some portfolios are clean. Most are not, and the ones that have passed through an estate, an operator acquisition, or a decade of inattention almost never are.

What professional management does provide is a complete and verified picture of what you own, a systematic check on what you are being paid against what you are owed, and someone whose responsibility it is to notice. For most owners, that is the difference between hoping nothing is falling through the cracks and knowing.
