Argued March 19, 2024

JUSTICE BLACKLOCK delivered the opinion of the Court.

Minerals that have already been processed or transported are
generally more valuable than the same minerals taken straight from the
ground. This difference in value can create confusion and controversy
between mineral producers and royalty holders. Many leases give the
royalty holder an interest in the minerals “at the well” or “at the
wellhead,” or they use other equivalent language indicating that the
royalty interest is in the minerals as they come out of the ground, not
after processing, transportation, or other “post-production” efforts have
increased the minerals’ value. Often, however, minerals are not sold
until after post-production efforts have increased their value, which
means the sale price available for a royalty calculation is on a more
valuable product than the “at-the-well” minerals in which the royalty
holder has an interest. In such a case, simply paying the royalty holder
his percentage of the sales price would result in a windfall, because he
owns a percentage of the minerals’ lower value “at the well,” not a
percentage of the minerals’ greater value after the expenditure of
post-production costs.
To account for this disparity—between the value of the product
when it is sold and the value of the product “at the well”—an
“at-the-well” royalty holder’s proportionate share of the post-production
costs expended to increase the value of the production must be accounted
for prior to payment of the royalty. As we recently observed, “[b]ecause
postproduction costs are not incurred until after gas leaves the wellhead,
and because postproduction costs add value to the gas, backing out the
necessary and reasonable costs between the sales point and the
wellhead is accepted as an adequate approximation of market value at
the well.” BlueStone Nat. Res. II, LLC v. Randle, 620 S.W.3d 380, 389
(Tex. 2021). We have called this way of accounting for post-production
costs “the workback method.” Id. at 388–89. “When the location for
measuring market value is ‘at the well’ (or equivalent phrasing), the
workback method permits an estimation of wellhead market value by
using the proceeds of a downstream sale and subtracting postproduction
costs incurred between the well and the point of sale.” Id.

The royalty holder in this case was unsatisfied with the reduced
royalty payment resulting from the producer’s accounting for
post-production costs. But the parties do not dispute that their lease
conveys an “at-the-well” royalty. And it has long been the law that the
holder of an “at-the-well” royalty must share proportionately in the
post-production costs expended on the products of the well prior to sale.
See, e.g., Burlington Res. Oil & Gas Co. v. Tex. Crude Energy, LLC,
573 S.W.3d 198, 206 (Tex. 2019); Chesapeake Expl., L.L.C. v. Hyder,
483 S.W.3d 870, 873 (Tex. 2016); French v. Occidental Permian Ltd.,
440 S.W.3d 1, 3 (Tex. 2014); Heritage Res., Inc. v. NationsBank, 939
S.W.2d 118, 122 (Tex. 1996). We recently summed up the longstanding
rule as follows: “When a mineral lease requires royalty to be computed
‘at the well,’ the royalty interest bears its usual share of postproduction
costs” unless the lease provides otherwise. Randle, 620 S.W.3d at 389.
This dispute appears to have arisen from the way the producer
accounted for post-production costs, a method with which we find no
fault. The producer used some of the gas produced from the well to
power post-production activities conducted off the lease on other gas
produced from the well. The value of the gas used for post-production
activities was a post-production cost of the kind normally chargeable to
the royalty holder. The producer accounted for this value by subtracting
the volume of gas it used in post-production from the total volume of gas
on which it calculated the royalty. The royalty holder sued, arguing that
the producer could not subtract the volume of gas used in
post-production because the lease required payment of a royalty on all
gas produced from the well.

The royalty holders, Anne Carl and related parties, rely primarily
on two lease provisions. The first obligates the producer, Hilcorp, to pay
a royalty “on gas . . . produced from said land and sold or used off the
premises.” Carl does not dispute that this royalty on gas “sold or used
off the premises” must be calculated based on “the market value at the
well of one-eighth of the gas so sold or used.” (Emphasis added.) Hilcorp
argues that, because this is an “at-the-well” royalty, it may subtract out
the value of the gas it uses in post-production activities before paying
Carl’s royalty. Carl objects that if the gas used in post-production is
removed from the royalty calculation, then she is not being paid for all
the gas “sold or used off the premises” (Emphasis added.) We agree
with Hilcorp.
Carl’s royalty on all gas “sold or used off the premises” does not
alter her obligation to bear the “usual share of postproduction costs” as
the holder of an “at-the-well” royalty. See Randle, 620 S.W.3d at 384,
389. Just as with other post-production costs that add to the value of
the minerals sold, the gas Hilcorp uses “off the premises” for
post-production activities must be accounted for when calculating Carl’s
“at-the-well” royalty. Carl is correct that she has a royalty interest in
all the gas produced, including the gas used off the premises. But in
order to calculate the at-the-well value of all the gas produced, Hilcorp
was entitled to account for reasonable post-production costs, which
include the value of the gas used off the premises to prepare other
royalty-bearing gas for sale. 1 Hilcorp’s accounting may have given Carl

for something other than post-production activities on other gas produced from

the impression that she was not being paid for all the gas produced, but
Carl was not shortchanged. Hilcorp’s calculation was one permissible
way to convert its downstream sales price into an at-the-well market
value on which to pay the royalty, as required by this lease.
Carl also relies on the following lease language: “Lessee shall
have free use of oil, gas, coal, wood, and water from said land, except
water from Lessor’s wells, for all operations hereunder, and the royalty
on oil, gas, and coal shall be computed after deducting any so used.” This
provision gives Hilcorp “free use” of gas “for all operations hereunder.”
Carl reasons that Hilcorp does not have “free use” of gas for operations
conducted off the lease, which she argues are not included in “operations
hereunder.” As a result, Carl says, Hilcorp does not have “free use” of
the gas it uses in post-production activities off the lease, so it must pay
royalty on that gas rather than subtracting it from the calculation in its
post-production-cost accounting.
Once again, Carl invokes a provision of the lease that has no
impact on her obligation, as the holder of an “at-the-well” royalty, to bear
the “usual share of postproduction costs.” Randle, 620 S.W.3d at 389.
The relevant question is not whether the lease entitles Hilcorp to “free
use” of the gas it uses in post-production activities. If the lease did so,
this might be an additional reason Hilcorp prevails. But we can assume
Carl is right that the lease does not do so. The fact remains that Carl,
as the holder of an “at-the-well” royalty, must share in post-production

the well, then a royalty would be due on the gas so used. We do not understand
Carl to make such an allegation.

costs—whether or not those costs include using some of the gas produced
from the well.
As the federal district court observed, Carl does not claim that the
gas Hilcorp used in post-production was not a genuine post-production
cost of the kind that would normally be shared by an “at-the-well”
royalty holder. 2021 WL 5588036, at *1, *5 (S.D. Tex. Nov. 30, 2021);
2022 WL 20699680, at *2 (S.D. Tex. Apr. 6, 2022). Instead, Carl’s
argument is that other clauses in the lease—coupled with our decision
in Randle—somehow override her usual obligation to bear her share of
post-production costs under her “at-the-well” royalty. The parties
certainly could have contracted for the outcome Carl seeks by allocating
post-production costs differently, but none of the provisions Carl cites
have any effect on the extent to which this royalty bears post-production
costs. By creating an “at-the-well” royalty, the parties indicated that
the royalty would bear those costs. None of the lease language Carl
relies on alters that arrangement.
Nor does our decision in BlueStone v. Randle have any particular
impact on the outcome, except that it reiterates the longstanding rule
that an “at-the-well” royalty “bears its usual share of postproduction
costs.” 620 S.W.3d at 389. Randle construed a “free-use” clause
resembling the one at issue here. But Randle neither said nor suggested
that “free-use” clauses change an “at-the-well” royalty holder’s
obligation to bear its share of post-production costs. Randle involved a
“gross-proceeds” royalty, which generally does not bear post-production
costs—so the question of how to account for post-production costs was
not before the Court at all in Randle. If the dispute between Carl and

6
Hilcorp were genuinely about what their “free-use” clause means, then
Randle might be of some assistance. But as explained above, the
“free-use” clause in this lease has no bearing on the outcome of the
dispute over how to account for post-production costs.
The federal district court correctly concluded that Carl’s reliance
on Randle, on the “free-use” clause, and on the “off-lease-use-of-gas”
clause, amounted to a distraction from the real issue between these
parties, which is post-production costs. On that issue, this lease leaves
no doubt. 2021 WL 5588036, at *3–4. Carl is entitled to a royalty on
the “market value at the well” of the gas sold or used, which means her
royalty bears its usual share of post-production costs, including the cost
of gas produced from the well and used off the lease to power
post-production activities on other gas from the well. See also Fitzgerald
v. Apache Corp., No. H-21-1306, 2021 WL 5999262, at *4–8 (S.D. Tex.
Dec. 20, 2021) (correctly rejecting substantially the same arguments
rejected by the district court in this case).
The first certified question reads as follows:
1. After Randle, can a market-value-at-the well lease
containing an off-lease-use-of-gas clause and
free-on-lease-use clause be interpreted to allow for the
deduction of gas used off lease in the post-production
process?
For the foregoing reasons, we answer Yes. 2

2 Attaching labels to general categories of lease clauses—e.g.,
“off-lease-use-of-gas” clause and “free-on-lease-use” clause—can give the
misimpression that all clauses to which those labels apply will operate in the
same way. To the contrary, all leases—and all clauses within them—should
be interpreted first and foremost based on what they say, not based on the

7
The Fifth Circuit also asks:
2. If such gas can be deducted, does the deduction
influence the value per unit of gas, the units of gas on
which royalties must be paid, or both?
The briefing in this Court does not address the second question.
The parties appear to agree that the question is primarily one of
accounting and that it does not impact their legal rights or ultimate
financial prospects. Our rough mathematical calculations indicate that,
in a situation like this one, either of the two accounting methods
described in the second question would yield the same royalty payment.
The parties’ lack of interest in the second question seems to confirm our
calculations. Without assistance from the parties, we decline to offer
further thoughts on the second question, other than to emphasize that
nothing in this opinion should be understood to state a preference for
any particular method of royalty accounting, so long as the accounting
results in the royalty holder being paid what he is lawfully owed.

labels we may use to describe their various parts. Two leases, both of which
contain a clause accurately labelled a “free-on-lease-use” clause, could very
well produce opposite results under the same facts, depending on their precise
wording and other relevant language in the lease.
