and Exchange
         Commission. Refer to Item 1203(d) of Regulation S-K.
Production and Price History, page 11

3.       Tell us how you considered the requirements with regard to disclosure
of production, by
         final product sold, for individual fields and/or geological formations
that contain 15% or
         more of your total proved reserves. Refer to Item 1204(a) of
Regulation S-K and Rule 4-
         10(a)(15) of Regulation S-X.

4.       Expand the disclosure of proved reserves to additionally provide the
net quantities, by
         individual product type, of proved developed and proved undeveloped
reserves at the
         beginning of the year ended December 31, 2015. Refer to FASB ASC
paragraph 932-
         235-50-4.
5.       Expand your disclosure of the changes in total proved reserves to
provide an appropriate
         narrative explanation of the significant changes related to each line
item other than
         production for each period presented. To the extent that two or more
unrelated factors are
         combined to arrive at the line item figure, your disclosure should
separately identify and
         quantify each individual factor that contributed to a significant
change so that the change
         in net reserves between periods is fully explained. Expand the
disclosure relating to
         revisions in the previous estimates of your reserves to identify such
factors as changes
         caused by commodity prices and/or well performance. Refer to FASB ASC
932-235-50-
         5.
