      File No. 001-16619

Dear Mr. Wohleber:

      We have reviewed your filing and have the following
comments.
We have limited our review of your filings to those issues we have
addressed in our comments.  Where indicated, we think you should
revise your document in response to these comments.  If you
disagree,
we will consider your explanation as to why our comment is
inapplicable or a revision is unnecessary.  Please be as detailed
as
necessary in your explanation.  In some of our comments, we may
ask
you to provide us with information so we may better understand
your
disclosure.  After reviewing this information, we may raise
additional comments.

	Please understand that the purpose of our review process is
to
assist you in your compliance with the applicable disclosure
requirements and to enhance the overall disclosure in your filing.
We look forward to working with you in these respects.  We welcome
any questions you may have about our comments or any other aspect
of
our review.  Feel free to call us at the telephone numbers listed
at
the end of this letter.

Form 10-K for the Fiscal Year Ended December 31, 2004

Developed and Undeveloped Acreage, page 4

1. We note that the geographical distribution of your net
developed
acreage differs greatly from that of your net undeveloped acreage.
We note that the majority of your net developed acreage is
primarily
concentrated in the United States and Europe, while your net
undeveloped acreage is primarily located in the Asia-Pacific,
Africa
and Other areas.  Please expand your management`s discussion and
analysis, capital resources and liquidity disclosure to explain to
investors the extent to which the geographical distribution of
your
operations is expected to change based on your current investment
in
developed and undeveloped acreage.    Consider providing a time
horizon over which this change could take place as well as a
discussion of the additional risks associated with operating in
different countries and operating environments (e.g., political,
on
versus off shore, primarily oil versus gas and other geological
and
development factors).

Management`s Discussion and Analysis of Financial Condition and
Results of Operations, page 30

Exploration and Production, page 32

2. We note your disclosure that you "Replaced 280% of 2004
production
largely as a result of the Westport merger;" and that you realized
an
"exploration-based production replacement of only 34%."  Due to
the
variable components of this ratio, please revise your discussion
to
address each of the following, without limitation.

* Describe how the ratio is calculated.  We would expect the
information used to calculate this ratio to be derived directly
from
the line items disclosed in the reconciliation of beginning and
ending proved reserve quantities, which is required to be
disclosed
by paragraph 11 of SFAS 69.

* Identify the status of the proved reserves that have been added
(e.g., proved developed vs. proved undeveloped). It is not
appropriate to calculate this ratio using:

o non-proved reserve quantities, or,

o proved reserve additions that include both proved reserve
additions
attributable to consolidated entities and investments accounted
for
using the equity method.
* Identify the reasons why proved reserves were added.

o The reconciliation of beginning and ending proved reserves,
referred to above, includes several line items that could be
identified as potential sources of proved reserve additions.
Explain
to investors the nature of the reserve additions, and whether or
not
the historical sources of reserve additions are expected to
continue,
and the extent to which external factors outside of managements`
control impact the amount of reserve additions from that source
from
period to period.

* Explain the nature of and the extent to which uncertainties
still
exist with respect to newly discovered reserves, including, but
not
limited to regulatory approval, changes in oil and gas prices, the
availability of additional development capital and the
installation
of additional infrastructure.

* Indicate the time horizon of when the reserve additions are
expected to be produced to provide investors a better
understanding
of when these reserve additions could ultimately be converted to
cash
inflows.

* Disclose how management uses this measure.

* Disclose the limitations of this measure.

Liquidity and capital resources, page 30

3. Please expand your managements` discussion and analysis to
explain
how the age and decline rate composition of your upstream asset
portfolio is expected to impact your cash flows in future periods.
Also, identify the extent to which recent changes in the quantity
of
your proved reserves/capacity as a result of acquisitions and
dispositions have changed the expected amount and/or timing of
cash
flows for next year and beyond.

Financial Statements

Note 1. The Company and Significant Accounting Policies

Goodwill and Other Intangible assets, page 85

4. We note that your second quarter 2004 goodwill impairment test
did
not result in an impairment charge.  Please clarify i) when you
test
goodwill for impairment on an annual basis by reporting unit and
ii)
whether or not it is the same date each year.  Refer to paragraph
26
of SFAS 142.  In addition, please clarify whether or not the
goodwill
resulting from your June 2004 acquisition of Westport was tested
for
impairment as part of your second quarter 2004 goodwill impairment
test.

Note 27. Segment Information, page 128

5. Please expand your disclosure to state the factors used to
identify your reportable segments and whether or not operating
segments have been aggregated as required by paragraph 26(a) of
SFAS
131.

Note 29. Costs Incurred in Crude Oil and Natural Gas Activities,
page
138

6. We note your inclusion of asset retirement obligations and your
footnote (4), which states that "Asset retirement costs represent
the
noncash increase in property, plant and equipment recognized when
initially recording liability for abandonment obligations
(discounted) associated with the company`s oil and gas wells and
platforms."  Please remove the asset retirement obligations line
item
as there is no provision for this line item in paragraph 21 and
Illustration 2 of SFAS 69.  Refer to our February 2004 industry
letter at
http://www.sec.gov/divisions/corpfin/guidance/oilgasletter.htm.

Note 33. Standardized Measure of and Reconciliation of Changes in
Discounted Future Net Cash Flows (Unaudited), page 146

7. We note your footnote (2), which states that "Estimated future
net
cash flows before income tax expense, discounted at 10%, totaled
approximately $17.0 billion, $13.2 billion and $10.3 billion, for
2004, 2003 and 2002, respectively."  As there is no provision for
this measure in paragraph 30 and Illustration 5 of SFAS 69, this
presentation appears to be a non-GAAP measure.  Please explain how
you have or intend to comply with the requirements of Item 10(e)
of
Regulation S-K and/or Regulation G.  Clarify whether the measure
is a
liquidity or a performance measure.  Refer to Release Number 33-
8176:
Conditions for Use of Non-GAAP Financial Measures, located at
http://www.sec.gov/rules/final/33-8176.htm.

Exhibits 31.1 and 31.2

8. We note that the wording of your certifications pursuant to
Section 302 of the Sarbanes-Oxley Act of 2002 does not precisely
match the language set forth in the Act.  In this regard, your
certifications include references throughout the certification to
the
annual report.  Refer to Item 601(b)(31) of Regulation S-K for the
exact text of the required Section 302 certification, and amend
your
exhibits as appropriate.  This comment also applies to you Forms
10-
Q.
