                     Form S-3, File No. 333-124908, as amended
                     Form 10-KSB
                     Form 10-QSB
                     File No. 0-15905

Dear Ms. Moncada-Terry:

         I am writing in response to the staff's comment letter dated June 27,
2005, on the above referenced filing.

Form 10-KSB for the Fiscal Year Ended December 31, 2004

Oil and Gas Exploration and Production Activities, page 4

1.       As a result of the placement of our interest in the Galveston Area
         Blocks 287 and 297 leases, we received proceeds of approximately
         $214,000 in 2005, of which approximately $74,000 was credited to the
         carrying value of these unevaluated leases and approximately $140,000
         was recorded as a gain.

         A well was drilled on the Galveston Area Block 297 lease in 2005 which
         was dry, this requires no adjustments to our financial statements. If
         the well had been successful, we would have received a 7.5% working
         interest after the working interest owners recover their costs in the
         leases. Since we have no costs subject to depletion in our full cost
         pool, no depletion would have been recorded.

Proved Reserves as of December 31, 2004 table, page 6

2.       We have revised the disclosures in response to your comment to present
         "Future Net Cash Outflows After Income Taxes" and "Present value of
         Future Net Cash Outflows After Income Taxes." Please see page 6 of
         the Amended 10-KSB. The revised


         disclosure is consistent with the requirements of Statement of
         Financial Accounting Standards No. 69 and required by U.S. Generally
         Accepted Accounting Principles.

Note 1 -- Organization and Significant Accounting Policies, page 37

Recognition of Pipeline Transportation Revenue, page 41

4.       Revenues from pipeline transportation are recorded when volumes of
         natural gas and oil have been physically transported to the delivery
         point specified in our customer contracts. Revenues recorded are based
         on the contract transportation fees multiplied by volumes delivered. We
         define "transported" as volumes that have been delivered pursuant to
         our contracts. The guidelines provided in SAB 104 provide that "revenue
         should not be recognized until it is realized or realizable and
         earned," since we recognize revenue based on volumes physically
         delivered whereby we have earned our fee, we believe that we are
         recording our revenues in accordance with SAB 104.

         We have revised the disclosures in response to your comment. Please see
         page 40 of the Amended 10-KSB.

         pages 46-47 of the Amended 10-KSB.

Note 9 - Related Party Transactions, page 47

6.       In November 2003, we converted a contingent obligation due from
         Drillmar into a convertible note, thus eliminating the contingent
         obligation. In 2002, we recorded a full impairment of our investment in
         Drillmar, and recorded a full reserve for the accounts receivable owed
         to us from Drillmar, due to Drillmar's working capital deficiency and
         delays in securing capital funding. The $162,000 convertible note from
         Drillmar was not recorded in November 2003 due to Drillmar's continued
         working capital deficiency and inability to secure capital funding. If
         Drillmar is able to pay the note and accrued interest we will record it
         as other income.

Note 13 - Supplemental Oil and Gas Information - Unaudited, page 50

8.       As reflected on page 50 of our Form 10-KSB for the year ended December
         31, 2004, we recognized a $25,809 gain from the sale of our working
         interest in High Island Block 34 in June 2004 in accordance with Rule
         4-10 (c) (6) (i) of Regulation S-X.

         As of June 2004, our reserves associated with High Island Block 34
         represented approximately 60% of the total reserves associated with our
         full cost pool. Pursuant to Rule 4- 10 (c) (6) (i), sales of oil and
         gas properties shall be accounted for as adjustments of capitalized
         costs, with no gain or loss recognized, unless such adjustments would
         significantly alter the relationship between capitalized costs and
         proved reserves. In this case, 60% of our proved reserves were sold
         which would significantly alter the relationship between capitalized
         costs and proved reserves if all the sales proceeds were recorded as an
         adjustment to capitalized costs, so we allocated 60% of the capitalized
         costs in the full cost pool to the High Island Block 34 property and
         credited the sales proceeds to that amount with the difference being
         recorded as a gain.

9.       We have revised the disclosures in response to your comment. Please see
         page 52 of the Amended 10-KSB.

10.      We used year-end prices to determine future net cash flows from our
         reserves. We have revised the disclosure in response to your comment.
