Dear Mr. Aldridge:

      We have reviewed your response letter and filings and have
the
following comments.  We have limited our review to those issues we
have addressed in our comments.  Please provide a written response
to
our comments.  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.

10-K for the fiscal year ended December 31, 2004

Note 1 - Organization and Summary of Significant Accounting
Policies,
page F-7

Derivative Instruments, page F-9

1. In your response to prior comment 6 from our letter dated April
26, 2005 you indicate the gas hedging contract that expired during
2003 was the only derivative instrument that required accounting
recognition of ineffectiveness.  Given that, please explain to us
why
you believe the remainder of your natural gas and crude oil cash
flow
hedges are perfectly effective at offsetting changes in the fair
value of the hedged forecasted transaction, and that no amount of
ineffectiveness should be recognized.  Please refer to Section 2
of
the Implementation Guidance found at Appendix A of SFAS 133 for
further information regarding assessing hedge effectiveness.

2. Your response to prior comment 7 from our letter dated April
26,
2005 states that you do "not expect any unrealized gains or losses
to
be reclassified into earnings within the next 12 months."  As
such,
please explain to us when you intend to include the gain or loss
included in accumulated other comprehensive income related to your
cash flow hedges in earnings.  Please note that  31 of SFAS 133
states that amounts in accumulated other comprehensive income
shall
be reclassified into earnings in the same period in which the
hedged
forecasted transaction affect earnings.

Please note the term "unrealized" as used in comment 7 from our
letter dated April 26, 2005, refers to those gains or losses that
have not been recognized in earnings.  As such, we reissue prior
comment 7.

  Closing Comments

      Please respond to these comments within 10 business days or
tell us when you will provide us with a response.  Please furnish
a
letter that keys your responses to our comments and provides any
requested information.  Detailed letters greatly facilitate our
review.  Please understand that we may have additional comments
after
reviewing your responses to our comments.

	You may contact Mark A. Wojciechowski at (202) 551-3759, or
in
his absence, Jenifer Gallagher at (202) 551-3706, if you have

matters.  Please contact me at (202) 551-3686 with any other
