When the operator's decimal and the deed arithmetic disagree, one of the two records is incomplete, and the reconciliation identifies which.
Net royalty acres can be computed two ways. The title route multiplies net mineral acres by the lease royalty fraction and by eight. The payment route multiplies the division order decimal by the gross unit acres and by eight. Where the interest is fully documented and correctly set up, the two results match.
A mismatch is evidence, not a verdict. It points to a question about the record interest, the lease, the unit, or the operator's setup. The review docket below records each variance, a likely cause, the document that would settle it, and its effect on the appraised conclusion.
The title figure is built first, from the vesting deed, later conveyances, probate records, and the lease in force on the effective date. The payment figure is built second, from the division order, the unit acres stated in the operator's title opinion or exhibit, and the royalty decimal on the owner line. Working the two independently prevents one from being bent to match the other.
The comparison is then stated as a difference in NRA and as a percentage. A variance of a fraction of one percent can be a rounding artifact of an eight-digit decimal. A variance of 10, 25, or 50 percent signals a structural cause.
Heirship fractions are the most frequent source. An owner who inherited a share of a share may hold one-sixteenth of a parent interest, while the operator is paying on a larger fraction from an older owner record, or a smaller one because a branch of the family has not been added. Each generation is written out as a fraction and checked against the probate record and any affidavit of heirship. The decimals across all owners in a unit should total 1.0000, and a total above or below that figure is an operator title problem that surfaces in every owner's check.
Unleased cotenants change the payment side. An owner who has not signed a lease may be paid differently, as a cost-sharing cotenant, with rules that depend on the state, or may be placed in suspense. The decimal printed for such an owner is not a royalty decimal, and the NRA formula does not apply to it unchanged.
Depth severances change the title side. A deed that conveyed minerals down to a stated depth, or that reserved deeper formations, splits one surface tract into separate estates. The operator may have set up the owner for all depths when the owner holds one, or for one depth when the owner holds both. Reservations in earlier deeds, expired leases, and pooling clauses belong on the same list.
Each cause is tied to a source: a recorded instrument, a probate order, an affidavit, a letter from the operator's division order department, or a corrected title opinion. The reconciliation docket then shows whether the appraisal adopts the title figure, the payment figure, or a range, and why. Where the document that would settle the question is not yet available, the item is carried as a limiting condition, and the appraisal states which figure it relies on and what changes if the other proves right.
An appraisal does not correct an operator's records. Corrections run through the operator, usually by submitting recorded documents to its land or division order department, and in contested cases through an oil and gas attorney. The appraisal's role is to show the variance and its effect on value so that the owner and the owner's advisers can decide what to pursue.
If the operator pays on more NRA than the title supports, the income evidence overstates the owner's position, and past overpayments may be subject to recovery by the operator. If the operator pays on less, the income evidence understates it, and underpaid revenue may be owed, subject to the limits on recovery that vary by state. The appraisal reports both effects and does not offer a legal conclusion on either.
Resolve these questions so the appraisal conclusion can be traced to a defined interest, date, method, and evidence set.
Neither is presumed correct. The deed shows ownership and the division order shows what is being paid. The reconciliation finds the cause of a difference and identifies which record needs the correction.
The operator is holding royalties unpaid, usually because of a title question, a missing signature, or an unresolved ownership dispute. Release generally requires the operator to receive the documents that cure the defect, and the rules vary by state.
Within rounding. The decimal is typically shown to eight places, so small differences are expected. Differences of several percent or more warrant a documented explanation.
Operators generally require proof of the transfer, such as a probate order, a recorded deed, or an affidavit of heirship, before updating the owner line. The specific documents depend on the operator and the state.
The unit may include owners the operator has not yet identified, an interest carried twice, or a decimal entered in error. The operator's title opinion lists every owner and the division of interest, and a total away from 1.0000 is usually resolved there first.
Carry the same effective date, interest definition, evidence hierarchy, and limitations into these related appraisal procedures.
