         reserves you added as extensions and discoveries are associated with
infill wells.

         Please note the staff believes that changes in reserves associated
with infill drilling should
         be categorized as revisions of previous estimates, rather than
extensions and discoveries,
         based on the guidance in Rule 4-10(a)(14) of Regulation S-X and
subparagraphs (a) and
         (d) of FASB ASC 932-235-50-5. Under this guidance, an extension well
is a well drilled
         to extend the limits of a known reservoir and results in an extension
of the proved acreage.

         However, infill drilling locations are already located within the
previously determined
         proved area and result in the recovery of known proved reserves. As a
result, changes in
         reserves relating to such wells should be classified as revisions of
previous estimates
         pursuant to the guidance in subparagraph (a) of FASB ASC 932-235-50-5.
Please revise
         the classifications within your reserves reconciliations and the
associated narratives
         accordingly.

Exhibit 99.1
Adjusted Operating Margin Reconciliation, page 20

2.       We have reviewed your response to prior comment 1. Please address the
following:

                Disclose how adjusted operating margin before the effects of
derivative settlements is
              used by management and is useful to investors;
                Disclose how adjusted operating margin including the effects of
derivative
              settlements is used by management and is useful to investors;
                Disclose why you reconcile to an adjusted operating margin
before the effects of
              derivative settlements and to adjusted operating margin including
the effects of
              derivative settlements; and
                Reconcile from your GAAP measure to your non-GAAP measures of
adjusted
              operating margin. Your current presentation places greater
prominence on the non-
              GAAP measure and is inconsistent with Question 102.10 of the
C&DI's on Non-
              GAAP Financial Measures.
3.       Adjusted operating margin before the effects of derivative settlements
and including the
         effects of derivative settlements appears to be a performance measure.
Please tell us the
         following:

                How you view an adjusted operating margin that excludes
operating expenses, such
              as, DD&A and asset retirement obligation accretions; and
                Why you exclude exploration costs and other operating expense,
net from your non-
              GAAP measures of adjusted operating margin.
