File No. 001-32395
Dear Mr. Wallette:
            We have limited our review of your filing to the financial statements and related
disclosures 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 these comments within ten business days by providing the requested
information or advise us as soon as possible when you will respond.  If you do not believe our
comments apply to your facts and circumstances, please tell us why in your response.
            After reviewing your response to these comments, we may have additional comments.

operations.  If the amount of natural gas production consumed in operations is material,
expand your discussion to separately disclose the net quantities of such production so that
the inconsistency with the gas production figures provided elsewhere in your filing is
reconciled.
3.If the proved reserves disclosed in your filing include material amounts of natural gas
consumed in operations, expand your disclosure to clarify the net amounts of such
reserves.  Refer to FASC ASC 932-235-50-10.
Proved Undeveloped Reserves, page 164
4.Your discussion of the changes that occurred due to revisions appears to indicate that the
downward revisions due to changes in development timing were partially offset by
positive changes due to higher prices.  To the extent that two or more unrelated factors are
combined to arrive at a change in the net quantities, your disclosure should separately
identify and quantify each individual factor so that the change in net quantities of reserves
between periods is fully explained.  In particular, disclosure relating to revisions in
previous estimates should identify such underlying factors as changes caused by
commodity prices, well performance, improved recovery, uneconomic proved
undeveloped locations or changes resulting from the removal of proved undeveloped
locations due to changes in a previously adopted development plan.  Refer to Item 1203(b)
of Regulation S-K.  This comment also applies to the comparable discussion, presented
elsewhere in your filing, of the changes in net quantities of total proved reserves for each
of the annual periods presented.  Refer to FASB ASC 932-235-50-5.
5.Your disclosure indicates that you transferred a material amount of proved undeveloped
reserves to developed reserves during the year.  Expand your disclosure to include a
discussion of the progress made during the year to convert proved undeveloped reserves to
proved developed reserves.  Refer to Item 1203(c) of Regulation S-K.
Acreage at December 31, 2018, page 173
6.Expand your disclosure to provide the expiration dates relating to material concentrations
of your undeveloped acreage.  Refer to Item 1208(b) of Regulation S-K.

7.Expand your disclosure to explain the circumstances supporting the disclosure of negative
undiscounted future net cash flows for Alaska and Canada in the presentation of the
standardized measure of discounted future net cash flows for the fiscal year ending
December 31, 2016.  Refer to the disclosure requirements under FASB ASC 932-235-50-
36 and the definition for proved reserves under Rule 4-10(a)(22) of Regulation S-X,
respectively.

flows.  Refer to FASB ASC 932-235-36.
Index to Exhibits
Exhibit Number 99, page 199
9.The report prepared by the third party petroleum engineering firm does not appear to
address all of the requirements pursuant to Item 1202(a)(8) of Regulation S-K.  Please
obtain and file revised reserves reports to address the following points.

•The reserves report should state the purpose for which the report was prepared, e.g. for
inclusion as an exhibit in a filing made with the U.S. Securities and Exchange
Commission (Item 1202(a)(8)(i)).

•The reserves report should include the date on which the report was completed (Item
1202(a)(8)(ii)).

and procedures as it considered necessary under the circumstances to prepare the
