Dear Mr. Stertzel,

Note 2 - Summary of Significant Accounting Policies

Fixed Assets, page F-8

    1.  We  note  your  proposed revised disclosure provided in response to our
        prior comment number  five.   Please  further expand this disclosure to
        address your accounting for development costs.

      We have updated the notes to the financials  to  indicate  our accounting
      policies related to Development Costs.

   2. We note your response to our prior comment number seven and are unable to
      agree  with  your conclusion.  Please note that paragraph 35 of  SFAS  19
      specifically requires  the use of the units of production method.  Please
      modify your financial statements  accordingly.  You may contact us if you
      wish to discuss this matter further.

      After discussions with the Commission,  our  auditor,  we have determined
      that in 2004 and 2005, the Company over depreciated some assets by virtue
      of  using  the  straight line depreciation method, rather than  units  of
      production.  For 2004, the company took depreciation related to leasehold
      improvements of $16,524,  whereas  the  actual  amount,  using  units  of
      production,  should  have  been  $13,517.   For  2005,  the  company took
      depreciation  related  to leasehold improvements of $38,405, whereas  the
      actual amount, using units of production, should have been $17,732.

      The aggregate of these two  differences  is $23,679 of over depreciation.
      The  company  has  reviewed Staff Accounting  Bulletin  1M  "Materiality"
      (added by SAB 99) and determined it is not necessary to restate the prior
      financial statements,  but  to  make  a cumulative adjustment in the 2005
      year end numbers when the company files  it's  10KSB  for 12/31/06 in the
      coming  weeks.  The 2005 and 2006 year end income statement  and  balance
      sheet will  be  presented  at  that  time, and the 2005 numbers (earliest
      period  presented)  will  be  adjusted.   The   notes  to  the  financial
      statements will additionally contain an explanation of the (1) reason for
      the change, (2) the effect on net income (loss),  and  (3)  the effect on
      earnings per share - basic and diluted.

      In  coming  to  this  conclusion,  the company determined that the  above
      adjustment would not have changed the  mind  of  a  potential user of the
      financial statements.  The adjustment, as a percentage  of  total assets,
      was less than 1% in both years.  The adjustment, as a percentage of total
      loss, was 1.64% and 2.27%, respectively.  Restating the prior filings and
      financials  to  increase  the earnings of the company (i.e. decrease  the
      loss) by such a small percentage, would not prove to be beneficial to the
      shareholders, the company or any other users to the financial statements.

      The company reviewed the SAB  to  determine  if  the  qualitative factors
      outweighed   the  quantitative  issues  as  well.   Again,  the   company
      determined  that  the  error  was  not  intentional,  nor  was  the  over
      depreciation  a  significant enough adjustment to change the readers mind
      or impression of the integrity of management.

      Below is the company's  analysis  of the effect on the depreciation taken
      vs. units of production method.


UNITS OF PRODUCTION                    			 2004       2005
- -------------------				      ---------	  --------
Total Cost                                  		668,189	   809,136
Salvage Value              10%                		 66,819     80,914
Total Est'd Units Avail                      		221,196    215,938

Depletion Cost Per Unit                		      $    2.72   $   3.37
Total production for year                       	  4,972      5,258
Revisions                                   		 (2,337)         -
Total Depletion amount                 		      $  13,517   $ 17,732
Net carrying value                           		654,671    791,404

Total depreciation taken                      		 16,524     38,405
Total depletion - corrected             	      $  13,517   $ 17,732
difference (less) more                 		      $   3,007   $ 20,673
(less) means that too little was taken,
	more means that to amend would
	provide income to the company
                          Total Assets   	      1,565,014  3,738,196
                                      			  0.19%      0.55%
                          Total Sales       		195,786    292,143
                                      			  1.54%      7.08%
                          Total Loss       	       (183,196)  (911,457)
                                      			 -1.64%     -2.27%

      As stated above, the company will make  a  cumulative  adjustment  to the
      financial  statements  on  the year end 12/31/06 10KSB which will reflect
      these adjustments in our 2005 presented financial statements.

   3. We note your response to our  prior  comment number eight. It appears you
      have not recorded your asset retirement  obligations.   Please  refer  to
      SFAS  143  and  modify  your  financial  statements accordingly.  You may
      contact us if you wish to discuss this matter further.

      We have updated the notes to the financials to state:

      "Pursuant  to  SFAS  143, the company is required  to  record  any  asset
      retirement obligations  when  they  become  determined.   The company has
      evaluated  the  expected  cost  both  current and in the future  for  its
      potential plugging obligation and has determined  that  the salvage value
      of the equipment and casing associated with those wells should  more than
      cover  the  costs  to  plug  the  wells.  Given that, the company has not
      recorded any potential plugging liability on the books."

Note 5 - Related Party Transactions, page F-12

   4. We have reviewed your response to prior comment number 11.  Please expand
      your note disclosure to indicate the  term of the loan agreements payable
      to Mr. Conradie and Mr. Griffith rather  than providing a cross reference
      to a previously filed document.
      We have updated the notes to the financials  to  detail  out the specific
      terms of the financing and repayment terms for the related party notes.

Note 10 - Warrants and Options, page F-14

   5. It appears your adoption of SFAS 123(R) was effective on January 1, 2006.
      Please  expand your disclosure to indicate when you adopted  SFAS  123(R)
      and also to disclose your method of accounting for such instruments prior
      to  January  1,  2006.   In  addition,  please  expand  your  disclosures
      regarding  recently  issued  accounting  pronouncements  to indicate what
      effect if any, your adoption of SFAS 123(R) is expected to  have  on your
      financial statements.

      We  have  updated  Note 10 address both pre-1/1/06 accounting policy,  as
      well as the adoption of SFAS 123R.

   6. We note in your impairment analysis, that you  are  using a 3.5% discount
      rate in your assumptions.  Please tell us your basis for this rate.

      We  used  the  historical  average  inflation  rate  of  3.5%   for   our
      calculation.    The   exact   amount   is   3.43%   for   1913-2006   per
      InflationData.com.

Note 4 - Reserves Quantity Information

Proved Developed and Undeveloped Reserves, page F-19

   7.  In  our  prior  comment  18, we asked that you revise your disclosure to
      incorporate year-end 2005 assumptions,  such as production costs, capital
      expenditure, product prices etc., in your  estimates  of  proved reserves
      and standardized measure.  Your draft amendment states "Our year end 2005
      assumptions  used  in evaluating the reserves at December 31,  2005  were
      based on the January  31,  2005  revised  report.   The  company  has not
      completed an additional report, thus the $32.55 price is used along  with
      the  future  production  costs  of  $960,682, future development costs of
      $3,146,000 and future provision for income taxes of $184,436."  Since you
      have not utilized year-end 2005 prices  and costs to estimate your proved
      reserve and standardized measure figures, these disclosures do not comply
      with  paragraphs 10 and 30 of SFAS 69.  Please  amend  your  document  to
      comply with SFAS 69.  Revise your proved undeveloped reserves so that the
      dates of first production correspond to the revised drilling schedule you
      referenced in your response prior comment number 19.

      We have updated the standardized measure figures to account for the delay
      in drilling and have amended the disclosures to reflect these changes.


   8. In your  response  to  prior comment 19, you state that you will commence
      drilling in the fourth quarter  of 2006.  Please explain to us the status
      of this drilling program.  Affirm  to  us,  if  true, that this refers to
      well locations for which you booked proved undeveloped  reserves at year-
      end 2005.

      The  company  has  not  yet initiated its drilling program on  the  wells
      indicated in the reserve report.  This is not due to a lack of ability or
      desire, but more of a shifting  of  resources  to  allow  the best use of
      funds.  Additionally opportunities have presented them self which provide
      a greater expected rate of return over the short term, thus the focus has
      been on these areas.  It is anticipated during the next 12 months for the
      company  to  initiate  the  drilling  program on the wells in the  booked
      proved undeveloped reserves areas.  Management  will  continually  assess
      the  value  on  the  books to insure it is reasonably booked and does not
      need an adjustment or impairment.
