       Dear Tom L. Ward:

              We have reviewed your draft registration statement and have the 
following comments. In
       some of our comments, we may ask you to provide us with information so 
we may better
       understand your disclosure.

              Please respond to this letter by providing the requested 
information and either submitting
       an amended draft registration statement or publicly filing your 
registration statement on
       EDGAR. If you do not believe our comments apply to your facts and 
circumstances or do not

response.

   1.                                                   Please expand your 
disclosure to clarify what percentage of your leases are supported by
                                                        your midstream 
infrastructure. In that regard, we note you state that one of your strengths
                                                        is that your midstream 
infrastructure significantly reduces lifting costs relative to other
                                                        operators.

2.       We note you disclose that your average cash operating costs during the 
year ended
         December 31, 2022, including the benefit of your midstream 
infrastructure assets, were
         $10.90 per barrel of oil equivalent, which is 27% lower on average 
than other
         unconventional focused operators, and 64% lower on average than other 
conventional
         focused operators during the same period. Please provide the basis for 
this statement and
         discuss whether such information is specific to comparable operations 
in the area in which
         your assets are located.
Risk Factor Summary, page 9

3.       Please expand your disclosure to highlight the risk that your general 
partner has a limited
         call right that may require investors to sell their common units at an 
undesirable time or
         price and that even if your unitholders are dissatisfied, they cannot 
remove your general
         partner without its consent.
Reconciliations of Adjusted EBITDA and Cash Available for Distribution to GAAP 
Financial
Measures, page 22

4.       The table on page 22 presently shows reconciliations between net 
income, Adjusted
         EBITDA, and cash available for distribution; and would therefore 
appear to require
         disaggregation into separate reconciliations, each starting with the 
most directly
         comparable GAAP measure, to comply with Item 10(e). In this regard, 
you state on page
         21 that the GAAP measures most directly comparable to cash available 
for distribution are
         net income and net cash provided by operating activities. Revise your 
disclosure to
         separately reconcile net income to cash available for distribution.
Risk Factors
Declining general economic, business or industry conditions and inflation may 
have a material
adverse effect on our results of operations..., page 41

5.       We note you disclose that you expect to experience supply chain 
constraints and
         inflationary pressure on your cost structure and that these pressures 
will likely continue to
         adversely impact your operating costs. Please update this risk factor 
in future filings if
         recent inflationary pressures have materially impacted your operations 
and identify the
         types of inflationary pressures you are facing and how your business 
has been affected.
Our Cash Distribution Policy and Restrictions on Distribution, page 68

6.       You disclose that your cash distribution policy is subject to various 
restrictions on
         distributions, including the financial tests and covenants that you 
must satisfy under the
         New Credit Facility. Please expand your disclosure to discuss these 
financial tests and
         covenants and if these expected covenants would have impacted the cash 
distributions on
         a pro forma basis for the last completed fiscal year and last twelve 
months, or may

Proved Undeveloped Reserves (PUDs), page 116

7.       The explanation accompanying the reconciliation of the changes that 
occurred in proved
         undeveloped reserves presented on page 116 indicates the overall 
change due to revisions
         of previous estimates (+37,468 MBoe) results from the change due to 
higher commodity
         prices (+1,446 MBoe) and various other changes including changes in 
the development
         plan, quantity estimates and forecast revisions (+36,022 MBoe).

         Please expand your explanation of the changes associated with the 
development plan,
         quantity estimates and forecast revisions to separately identify and 
quantify each
         contributing factor, including offsetting factors, so the change is 
fully reconciled. Refer to
         the disclosure requirements in Item 1203(b) of Regulation S-K. This 
comment also applies
         to the explanation of the changes in total proved reserves that 
occurred due to revisions
         and for each period presented on pages F-5 to F-6, F-32, F-56 and 
F-80,
         respectively. Refer to the disclosure requirements in FASB ASC 
932-235-50-5.
Developed and Undeveloped Acreage
Undeveloped Acreage Expirations, page 120

8.       We note your disclosure of near-term undeveloped acreage expirations. 
Please expand
         your disclosure to clarify if any proved undeveloped reserves have 
been assigned to
         locations on this acreage which are scheduled to be drilled after 
lease expiration. If there
         are material quantities of net proved undeveloped reserves related to 
such locations,
         expand your disclosure to explain the steps necessary to extend 
acreage expiration dates.
         Refer to Rule 4-10(a)(26) of Regulation S-X.

requirements in Item 1206

Executive Compensation and Other Information
Equity Incentives, page 139

11.      We note you disclose that your Named Executive Officers received 
one-time awards of
         Mach Company Class B Units and that in connection with the completion 
of this offering,
         any unvested Mach Company Class B Units held by the Named Executive 
Officers are
         expected to fully vest immediately prior to the consummation of the 
offering. We also
         note you disclose on page F-29 that the Class B Units allow the holder 
to participate in
         distributions once the company's Class A shares have met a certain 
requisite financial
         internal rate of return in accordance with the LLC agreement. Please 
revise to clarify the
         material terms of the Class B Units, the significance of vesting and 
who will be
         responsible for any distributions made in connection with the Class B 
Units or tell us why
         you do not believe such information is material. In addition, file as 
exhibits the
         agreements governing the terms of the incentive units held by 
management. Refer to Item
         601(b)(iii)(A) of Regulation S-K.

13.      We note the definition for an exploratory well excludes the second 
sentence of the SEC
         definition. Please expand the definition to include the remaining 
sentence. Also, expand
         your glossary to include the definition for an extension well. Refer 
to the definitions in
         Rule 4-10(a)(13) and (a)(14) of Regulation S-X.
Pro Forma Financial Statements, page F-2

14.      We note you disclosed on page F-2 that although all entities to be 
contributed in the
         Reorganization Transactions have a high degree of common ownership, no 
individual
         controls any of the entities, therefore the transactions will not be 
accounted for as common
         control transactions. You identified BCE- Mach III LLC as the 
Predecessor and disclosed
         that the acquisitions of BCE-Mach LLC and BCE-Mach II LLC by BCE-Mach 
III LLC
         will be accounted for at fair values in accordance with the business 
combination guidance
         in ASC 805. Please address the following:

         Tell us how you determined that BCE-Mach III was the Predecessor for 
accounting and
         reporting purposes.

         Provide to us your accounting analysis that supports your conclusion 
that none of the
         contributed entities are under common control, including a detailed 
organizational
         diagram depicting the ownership structure and related ownership 
percentages of the
         contributed entities both before and after the Reorganization 
Transactions and the
         offering. Please refer to ASC 805-50 for guidance including the 
examples in ASC 805-
         50-15-6.

         If your analysis responding to the above comment still concludes no 
common control,
         then tell us how you have considered the guidance in ASC 805-50-05-7 
and ASC 805-50-
         30-7 pertaining to the formation of a master limited partnership in 
concluding that a new
         basis of accounting was appropriate for BCE-Mach and BCE-Mach II.
15.      On page 146 you disclose that in connection with this offering, the 
Company will enter
         into a management services agreement (   MSA   ) with Mach Resources. 
Tell us whether
         there are significant differences in the fee or cost structure of the 
new MSA compared to
         the existing MSAs for which pro forma adjustments, including 
explanations for any
         assumptions involved, would be required pursuant to Rules 11-01(a)(8) 
and 11-02(a)(8) of
         Regulation S-X.
