1.     We note total proved PV-10 is disclosed as $1,890 million, which based
on the

revenues
       associated with the Company   s ownership share of revenues processed
through a
       Company owned plant.

       Please tell us the total dollar amount of the midstream revenues
included in the PV-10
       and standardized measure for each period disclosed here and on page 108.

       Also, please explain your justification for the inclusion of midstream

       As part of your explanation, please tell us the    terminal point
where the oil and gas
       production function ends and confirm you have a revenue interest in the
production at
       that point. Additionally, explain how the plant revenues and costs
relate to the
       processing fees applied to the Company   s production volumes, and if
any revenues
       from processing third-party gas is applied to offset such costs.

2.     We note disclosure on page two clarifying the estimates of proved
reserves and
       related PV-10, as of December 31, 2024, were prepared by Cawley,
Gillespie
       & Associates. Please expand your disclosure under the section

       (Exhibits 99.2 and 99.3), are not included in the estimates of proved

Proved Reserves Summary, page 106

5.     For the years ended December 31, 2022, 2023, and 2024, we note the
changes in your
       estimates of total proved reserves included    revisions of previous
estimates    due to: 1)
       the addition of PUDs and 2) the addition of proved developed producing
reserves
       associated with the drilling of wells within proved areas that were not
booked as
       PUDs at the prior year-end, and that you added no new reserves as
extensions and
       discoveries    during these periods.

       Please expand your disclosure to explain in reasonable detail why
reserves for these
       locations are classified as    revisions of previous estimates    and
not    extensions and
       discoveries.    Refer to the disclosure requirements in FASB ASC
932-235-50-5.

       This comment also applies to the disclosure on page four of the changes

2024.
6.     Please expand your separate disclosure of the proved developed reserves
and proved
       undeveloped reserves to include the volumes for the beginning period of
the

plugging
       expenses, net of salvage and net capital investment. Please provide us

31, 2024.

       Please explain your rationale for any material differences in these
undiscounted costs.
