We
have considered your response to our prior comment number four in
which
you state you cannot reasonably estimate the potential write down
because
you do not know what oil and natural gas prices will be in future
periods. We note in paragraph 2 of SFAS 5 that not all
uncertainties inherent in the accounting process give rise to
contingencies. However, we believe that the ability to recover
the value of your oil and gas assets under the ceiling test represents
a
loss contingency covered by SFAS 5, as resolution of uncertainties
regarding future gas prices may confirm
the
|
|
|
impairment
of your oil and gas assets. Accordingly, please disclose that
an estimate of the possible loss or range of loss cannot be
made. In addition, enhance your discussion and analysis of your
critical thinking accounting policies related to the full-cost ceiling
test on page 58 to provide a sensitivity analysis showing the effect
that
reasonably likely changes in your estimates used in calculation of
the
ceiling test as of December 31, 2006, may have on your financial
position
and results of operations:

We
note your response to comment 6 in our letter of September 17,
2007. Provide a discussion of your reserve replacement cost
calculation similar to that which you have provided in your
response. Also, provide an additional reserves replacement cost
measure that includes the estimated costs to develop the proved
undeveloped reserves.

In
our prior comment 14, we asked that you disclose your historical
oil and
gas prices so the reader is informed of the past effects of your
hedging
program. Our intent here is that you disclose your historical
prices before and after the effects of your hedging
program.
