                                       13


Item 5.  Interest in Securities of the Issuer

(a) and (b)

         The information contained on the cover pages of this Schedule 13D is
incorporated herein by reference.

         OCM GW directly holds the Issuer's Common Stock (or, as discussed
below, the Issuer's preferred stock into which the Common Stock is convertible)
and has sole power to vote and dispose of the Issuer's Common Stock (or, as
discussed below, the Issuer's preferred stock into which the Common Stock is
convertible).

         OCM GW owns 1,238,486 shares of Common Stock, and has the right to
acquire an additional (1) 5,078,582 shares of Common Stock pursuant to
conversion of the Series G Preferred Stock, par value $0.01 per share, of the
Company (the "Series G Preferred Stock"), which votes on an as-converted basis
with the Common Stock, and (2) 285,715 shares of Common Stock pursuant to
conversion of the Series H Preferred Stock, par value $0.01 per share, of the
Company (the "Series H Preferred Stock"), which votes on an as-converted basis
with the Common Stock.

         As disclosed in the Initial 13D, as dividends accrue on the Series G
Preferred Stock and are paid on the Series H Preferred Stock, OCM GW's
beneficial ownership of Common Stock will increase, as accrued dividends on the
Series G Preferred Stock are convertible into Common Stock by and the Series H
Preferred Stock pays quarterly dividends of Common Stock to the holders thereof.

         The Series G Preferred Stock provides for an 8% cash dividend,
expressed as a percentage of the stock's $500 liquidation value plus accrued and
unpaid dividends, which will accrue but not be paid until the dividend owing
April 1, 2009 is required to be paid, at which time the Company will commence
quarterly dividend payments. Deferred dividends may be paid to the extent the
board of directors elects to do so. Accrued dividends on the Series G Preferred
Stock may be converted to Common Stock at a conversion price of $9.00 (subject
to adjustment for recapitalizations and similar events). Accrued and unpaid
deferred dividends are to be paid on liquidation or, at the Company's option,
with the consent of the holders affected, at any time.

         Holders of the Series H Preferred Stock are entitled to quarterly
dividends of one share of Common Stock per share of Series H Preferred Stock, or
four shares of Common Stock annually per share of Series H Preferred Stock
(subject to adjustment for recapitalizations and similar events).

         The Oaktree Fund, in its capacity as the managing member of OCM GW, has
the ability to direct the management of OCM GW's business, including the power
to vote and dispose of securities held by OCM GW; therefore, the Oaktree Fund
may be deemed to beneficially own the shares of Common Stock of the Issuer held
by OCM GW.

         The Fund GP, in its capacity as the general partner of the Oaktree
Fund, has the ability to direct the management of the Oaktree Fund's business,
including the power to direct the decisions of the Oaktree Fund regarding the
vote and disposition of securities held by OCM GW; therefore, the Fund GP may be
deemed to beneficially own the shares of Common Stock of the Issuer held by OCM
GW.


                                       14


         GP I, in its capacity as the managing member of the Fund GP, has the
ability to direct the management of the Fund GP's business, including the power
to direct the decisions of the Fund GP regarding the vote and disposition of
securities held by OCM GW; therefore, GP I may be deemed to have indirect
beneficial ownership of the shares of the Issuer's Common Stock held by OCM GW.

         Capital I, in its capacity as the general partner of GP I, has the
ability to direct the management of GP I's business, including the power to
direct the decisions of GP I regarding the vote and disposition of securities
held by OCM GW; therefore, Capital I may be deemed to have indirect beneficial
ownership of the shares of the Issuer's Common Stock held by OCM GW.

         Holdings I, in its capacity as the general partner of Capital I, has
the ability to direct the management of Capital I's business, including the
power to direct the decisions of Capital I regarding the vote and disposition of
securities held by OCM GW; therefore, Holdings I may be deemed to have indirect
beneficial ownership of the shares of the Issuer's Common Stock held by OCM GW.

         Holdings, in its capacity as the managing member of Holdings I, has the
ability to direct the management of Holding I's business, including the power to
direct the decisions of Holdings I regarding the vote and disposition of
securities held by OCM GW; therefore, Holdings may be deemed to have indirect
beneficial ownership of the shares of the Issuer's Common Stock held by OCM GW.

         OCG, in its capacity as the managing member of Holdings, has the
ability to direct the management of Holdings' business, including the power to
direct the decisions of Holdings regarding the vote and disposition of
securities held by OCM GW; therefore, OCG may be deemed to have indirect
beneficial ownership of the shares of the Issuer's Common Stock held by OCM GW.

         OCGH, in its capacity as the majority holder of the voting units of
OCG, has the ability to appoint and remove directors of OCG and, as such, may
indirectly control the decisions of OCG regarding the vote and disposition of
securities held by OCM GW; therefore, OCGH may be deemed to have indirect
beneficial ownership of the shares of the Issuer's Common Stock held by OCM GW.

         OCGH GP, in its capacity as the managing member of OCGH, has the
ability to direct the management of OCGH's business, including the power to
direct the decisions of OCGH regarding the vote and disposition of securities
held by OCM GW; therefore, OCGH GP may be deemed to have indirect beneficial
ownership of the shares of the Issuer's Common Stock held by OCM GW.

         With respect to the shares of Common Stock reported herein, each of the
Reporting Persons may be deemed to have sole voting and dispositive power or the
sole power to direct the vote and disposition of the number of shares of Common
Stock which such Reporting Person may be deemed to beneficially own as set forth
above.

         Neither the filing of this Schedule 13D nor any of its contents shall
be deemed to constitute an admission by any of the Reporting Persons, other than
OCM GW, that it is the beneficial owner of any of the Common Stock referred to
herein for the purposes of Section 13(d) of the Act, or for any other purpose,
and such beneficial ownership is expressly disclaimed by each Reporting Person,
other than OCM GW.


                                       15


         As described in Item 6, OCM GW entered into agreements with third
parties regarding the Issuer's capital stock in connection with its initial
purchase of the Issuer's capital stock. As of the date hereof, to the knowledge
of the Reporting Persons, based on 4,815,280 shares of the Common Stock
outstanding, Bargus Partnership, Schultes Family Partnership, Richard Schultes
and 4-Sibs, LLC, each holds shares of the Series H Preferred Stock convertible
into 7,143 shares of the Common Stock and 50, 5,463, 150 and 5,463 shares,
respectively, of the Common Stock (in each case, less than 1% of the outstanding
shares), and William Jefferys holds 10 shares of Series H Preferred Stock
convertible into 1,429 shares of Common Stock and 30 shares of Common Stock
(less than 1% of the outstanding shares) (which parties executed, or are
successors to parties that executed, the Omnibus and Release Agreement described
in Item 6, and continue to hold Series H Preferred Stock). In addition, the
purchasers of the Series G Preferred Stock pursuant to the Second Series G
Subscription Agreement, described in Item 6, own (or may be deemed to
beneficially own) Common Stock in the following amounts and percentages, based
on 4,815,280 shares of the Common Stock outstanding (unless otherwise indicated,
shares of Common Stock are shares receivable upon conversion of the Series G
Preferred Stock held by such person): Allan Keel - 548,734 shares (10.26%,
including 39,734 shares issuable upon conversion of the Series G Preferred
Stock, 3,000 shares issuable upon exercise of warrants and 486,000 shares upon
exercise of options); Robert Blevins - 33,112 (less than 1%); Greg Pipkin -
360,836 shares (6.33% including 33,112 shares issuable upon conversion of the
Series G Preferred Stock); Jim Parkman - 33,112 shares (less than 1%); Tom
Petrie - 33,112 shares (less than 1%); Jon Hughes - 33,112 shares (less than
1%); Jonathan Linker - 33,112 shares (less than 1%); Tim Saxman - 6,623 shares
(less than 1%); Harry Perrin - 2,649 shares (less than 1%); Martha Perrin -
3,312 shares (less than 1%); and Randy King - 33,112 shares (less than 1%). To
the knowledge of the Reporting Persons each such shareholder, subject to the
transfer restrictions set forth in the Omnibus and Release Agreement and Second
Series G Subscription Agreement, has sole power to vote and dispose of the
shares held by such shareholder.

         The Reporting Persons, together with certain other shareholders of the
Company referred to herein that are parties to the Omnibus and Release Agreement
or any other agreement described herein, may constitute a "group" for purposes
of Rule 13d-5 under the Exchange Act with respect to their respective beneficial
ownership of the shares of Common Stock at the time of the applicable event
requiring disclosure in this Schedule 13D. Each Reporting Person disclaims the
existence of a "group" and disclaims beneficial ownership of all shares of the
Common Stock other than any shares reported herein as being held of record by
it. The filing of this Schedule 13D shall not constitute an admission that the
Reporting Persons and such persons constitute a "group" for purposes of Rule
13d-5 promulgated under the Act.

         To the knowledge of the Reporting Persons, none of the Covered Persons
directly owns any shares of Common Stock; provided, however, that because of
each Covered Persons status as a manager, general partner, director, executive
officer or member of a Reporting Person, a Covered Person may be deemed to be
the beneficial owner of the shares of Common Stock beneficially owned by such
Reporting Person. Each of the Covered Persons disclaims beneficial ownership of
the shares of the Issuer's Common Stock reported herein and the filing of this
Schedule 13D shall not be construed as an admission that any such Covered Person
is the beneficial owner of any securities covered by this statement.

         (c) Except as set forth herein (including with respect to quarterly
dividends that have accrued or are payable, or have been paid, in respect of the
Series G Preferred Stock and Series H Preferred Stock), to the knowledge of the
Reporting Parties, with respect to the other persons named in response to
paragraph (a), none of the persons named in response to paragraph (a) has
effected any transactions in shares of the Common Stock during the past 60 days.

         (d) Not applicable.

         (e) Not applicable.

Item 6.  Contracts, Arrangements, Understandings or Relationships With Respect
to the Securities of the Issuer

         Purchase Agreement

         See Item 4 with respect to the Purchase Agreement. A copy of the
Purchase Agreement is attached hereto as Exhibit 99(f).

         Subscription Agreements

         As disclosed in the Initial 13D, pursuant to a Subscription Agreement
dated February 28, 2005 (the "Series G Subscription Agreement"), between OCM GW
and the Company, OCM GW purchased 81,000 shares of Series G Preferred Stock, for
a purchase price of $40,500,000. As disclosed in the Initial 13D, pursuant to a
Subscription Agreement dated February 28, 2005 (the "Series A Subscription
Agreement"), between OCM GW and GulfWest Oil & Gas Company, a wholly owned
subsidiary of the Company, OCM GW purchased 2,000 shares of the subsidiary's
Series A Cumulative Exchangeable Preferred Stock, par value $0.01 per share, for
a purchase price of $1,500,000, which, as disclosed in the Initial 13D, was
subsequently exchanged for the Series H Preferred Stock.

         As disclosed in the Initial 13D, pursuant to a Subscription Agreement
dated February 28, 2005 (the "Second Series G Subscription Agreement" and
collectively with the Series G Subscription Agreement and Series A Subscription
Agreement, the "Subscription Agreements"), OCM GW sold 4,300 shares of Series G
Preferred Stock at a price of $500 a share, the same price at which OCM GW
acquired the shares, to a limited number of individuals consisting of management
and related or affiliated parties. The purchasers of Series G Preferred Stock
are subject to a right of first offer in favor of OCM GW, but not with respect
to shares of Common Stock received upon conversion, and are required to convert
their shares to Common Stock when OCM GW and its affiliates convert their shares
into Common Stock in the same proportion as OCM GW and its affiliates. The
purchases of the Series G Preferred Stock also have tag-along rights if OCM GW
proposes to transfer 10% or more of its Series G Preferred Stock to an
unaffiliated third party, and OCM GW has drag-along rights over such purchasers
with respect to transfers of Series G Preferred Stock representing over 50% of
the voting power of the Issuer's capital stock.

         Shareholders Rights Agreement

         As disclosed in the Initial 13D, OCM GW and the Company have entered
into a Shareholders Rights Agreement (the "Shareholders Rights Agreement") dated
February 28, 2005 providing OCM GW with up to four demand registrations with
respect to shares of Series G Preferred Stock and Common Stock (including the
shares of Common Stock acquired from Waggoner) upon the request of holders
holding 50% or more of the registrable securities on an as converted basis, and
unlimited piggyback registration rights.

         Pursuant to the Shareholders Rights Agreement, OCM GW is entitled to
receive monthly financial reports, an annual business plan and operating budget
of the Company, periodic filings and other information, in addition to board
observation rights. Further, the Shareholders Rights Agreement subjects the
Company to various restrictive covenants affecting operation of its business.

         Under the Shareholders Rights Agreement OCM GW has a right of first
refusal to purchase any additional securities proposed to be purchased by a
third party from the Company.


                                       17


         Omnibus and Release Agreement

         As disclosed in the Initial 13D, pursuant to an Omnibus and Release
Agreement ("Omnibus and Release Agreement"), among OCM GW, the Company and
certain shareholders of the Company, dated February 28, 2005, such shareholders
are prohibited from (so long as they hold shares of Series H Preferred Stock),
directly or indirectly, entering into any swap, option, future, forward or other
similar agreement that transfers, in whole or in part, any of the economic
consequences of ownership of any Series H Preferred Stock or Common Stock,
although such holders may sell the Common Stock or the Series H Preferred Stock.
OCM GW and its affiliates have a right of first refusal to acquire any Series H
Preferred Stock if a third party offers to acquire that stock, and the
signatories to the Omnibus and Release Agreement have certain piggyback
registration rights. The restrictions imposed upon the shareholders of the
Company that have executed the Omnibus and Release Agreement (or their
successors) do not apply to shares of Common Stock owned by these shareholders,
whether received upon conversion of the Series H Preferred Stock or otherwise,
except as disclosed above. OCM GW waived these transfer restrictions with
respect to Waggoner, as he was also a party to the Share Transfer Restriction
Agreement described below.

         The description contained in this Item 6 of the various agreements
summarized above are qualified in their entirety by reference to the full text
of such agreements, which are incorporated herein by reference and filed as
exhibits hereto.

         Share Transfer Restriction Agreement and Irrevocable Proxy

         As disclosed in the Initial 13D, Waggoner has entered into a Share
