Result: 0.00503906
The booklet multiplies the rounded unit decimal .011719 by 43% and prints .00503917. Unrounded, the result is 0.0050390625. The checker reports the booklet’s figure as a rounding difference, not a mismatch.

A decimal is a product of several inputs, so a mismatch usually traces to one of them. The back-solver holds every other input fixed and asks what value of each one alone would reproduce the decimal on your stub. A result that lands on a clean fraction, such as exactly half your acres or a 3/16 royalty, is the first thing to check.
Common sources: the payor may credit you with a different share of the acreage than your records show, the unit may not be the size you assumed, your lease royalty may differ from the rate you entered, part of your royalty may belong to someone else under a non-participating royalty (NPRI), or a multiunit well may allocate only part of its production to your unit.
In Oklahoma, every payment must show the owner’s interest as a decimal, and revenue decimals must be calculated to at least the sixth decimal place (52 O.S. § 570.12). A division order cannot change your lease: terms that conflict with the lease are invalid unless previously agreed (52 O.S. § 570.11).
In Texas, a division order states the fractional or decimal interest claimed by the payee, and it does not amend any lease (Tex. Nat. Res. Code § 91.402(c)). Division orders are terminable by either party on 30 days’ written notice (§ 91.402(g)).
In North Dakota, the operator or payor must give the mineral owner a statement of the net mineral acres, the gross mineral acres in the spacing unit and the decimal within 120 days after first sale or a change (N.D. Admin. Code § 43-02-06-01.1). If you disagree over your interest, the developer must furnish a description of the conflict and the proposed resolution, or the part of the title opinion that concerns your interest (N.D.C.C. § 47-16-39.4).
A payor calculates a decimal from the net acres it credits to the owner, the unit acres, the royalty fraction and any burden or allocation factor, and its owner relations department is the office that holds those inputs. The owner letter templates include a division order correction request. A division order is compared against the lease it rests on; see do you have to sign a division order. An oil and gas attorney can advise on a specific discrepancy.
It is your share of the production or proceeds from a well, written as a decimal. In Oklahoma it is the royalty fraction you own in your tract multiplied by the proportion that your tract’s acreage bears to the whole unit (52 O.S. § 87.1(e)).
Oklahoma requires revenue decimals to be calculated to at least the sixth decimal place (52 O.S. § 570.12(B)(1)). Enter every digit on your stub so the checker compares at the same precision.
Usually one input differs: the net acres credited to you, the unit acres, the royalty fraction, a non-participating royalty burden, or a multiunit allocation. The back-solver shows which single input would reproduce your stated decimal.
Multiply your unit decimal by the allocation factor for your unit. In Oklahoma that factor is the length of the completion interval in your unit divided by the whole completion interval (52 O.S. § 87.8(B)(1)), and the final multiunit order lists it.
It treats a fixed NPRI as a fraction of production, so that decimal does not change with the lease royalty, and a floating NPRI as a fraction of the royalty, so it moves with the lease royalty. Which one a deed creates depends on its wording; a title attorney can read yours.
No, in Texas, Oklahoma and North Dakota. Texas says a division order does not amend any lease (Tex. Nat. Res. Code § 91.402(c)(2)); Oklahoma says conflicting terms are invalid unless previously agreed (52 O.S. § 570.11); North Dakota says a division order that varies the lease is invalid to the extent of the variance (N.D.C.C. § 47-16-39.3).
No. The checker does arithmetic on the numbers you enter. Your title, lease and the payor’s records decide your actual interest. Consult an oil and gas attorney for a title or payment dispute.
