Forward-looking statements in this prospectus are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements may include statements that relate to: o our business plans or strategies, and projected or anticipated benefits or other consequences of such plans or strategies; o our objectives; o projected and anticipated benefits from future or past acquisitions; and o projections involving anticipated capital expenditures or revenues, earnings or other aspects of capital projects or operating results. Forward-looking statements generally can be identified by the use of words such as "may," "will," "expect," "intend," "estimate," "anticipate" or "believe" or similar language. Forward-looking statements are not guarantees of future performance and all phases of our operations are subject to a number of uncertainties, risks and other influences, many of which are beyond our control. Any one of such influences, or a combination, could materially affect the results of our operations and the accuracy of the forward-looking statements that we make. You are cautioned that all forward-looking statements involve risks associated with OMNI's dependence on activity in the oil and gas industry, labor shortages, international expansion, dependence on significant customers, seasonality and weather risks, competition, technological evolution and other risks detailed in the Company's filings with the Securities and Exchange Commission. Additional important factors that could cause actual results to differ materially from the anticipated results or other expectations expressed in our forward-looking statements are discussed under the caption "Risk Factors" below. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date that they are made. We undertake no obligation to publicly update our forward-looking statements. RISK FACTORS You should carefully consider the following risk factors, in addition to the other information set forth or incorporated by reference in this prospectus, before purchasing shares of our common stock. Each of these risk factors could adversely affect our business, operating results and financial condition, and also adversely affect the value of an investment in our common stock. INDUSTRY VOLATILITY MAY ADVERSELY AFFECT OUR RESULTS OF OPERATIONS. The demand for our services depends on the level of capital expenditures by oil and gas companies for developmental construction and these expenditures are critical to our operations. The levels of such capital expenditures are influenced by: o oil and gas prices and industry perceptions of future price levels; o the cost of exploring for, producing and delivering oil and gas; o the ability of oil and gas companies to generate capital; 3 o the sale and expiration dates of leases in the United States; o the availability of current geophysical data; o the discovery rate of new oil and gas reserves; and o local and international political and economic conditions. The cyclical nature of the oil and gas industry has a significant effect on our revenues and profitability. Historically, prices of oil and gas, as well as the level of exploration and developmental activity, have fluctuated substantially. This has, in the past, and may, in the future, adversely affect our business. We are unable to predict future oil and gas prices or the level of oil and gas industry activity. A prolonged low level of activity in the oil and gas industry will likely depress development activity, adversely affecting the demand for our products and services and our financial condition and results of operations. OUR GROWTH AND GROWTH STRATEGY INVOLVES RISKS. We have grown over the last several years through internal growth and acquisitions of other companies. It will be important for our future success to manage our rapid growth and this will demand increased responsibility for management personnel. The following factors could present difficulties to us: o the lack of sufficient executive-level personnel; o the successful integration of the operations of American Helicopters, Inc. including the integration of a management team with no history of working together; o increased administrative burdens; and o increased logistical problems of large, expansive operations. If we do not manage these potential difficulties successfully, they could have a material adverse effect on our financial condition and results of operations. WE HAVE INCURRED NET LOSSES IN PREVIOUS YEARS. Our past financial history reflects annual net losses. Our more recent history, however, reflects annual net incomes. While we hope to continue to generate increased revenues and profitability, any such increase may not be sustainable or indicative of future results of operations. We do intend to continue investing in internal expansion, infrastructure, integration of acquired companies into our operations and our marketing and sales efforts. THE DANGERS INHERENT IN OUR OPERATIONS AND THE POTENTIAL LIMITS ON INSURANCE COVERAGE FOR CERTAIN RISKS COULD EXPOSE US TO POTENTIALLY SIGNIFICANT LIABILITY COSTS. Our seismic operations are subject to risks or injury to personnel and loss of equipment. Our crews often conduct operations in extreme weather, in difficult terrain that is not easily accessible, and under other hazardous conditions. In addition, our aviation operations are subject to numerous hazards inherent in the operation of helicopters and airplanes. These hazards include adverse weather conditions, crashes, explosions, collisions and fires, all of which may result in injury to personnel or loss of equipment. We maintain what we believe is prudent insurance protection. However, we cannot assure that our insurance will be sufficient or effective under all circumstances. A successful claim for which we 4 are not fully insured may have a material adverse effect on our revenues and profitability. We do not carry business interruption insurance with respect to our operations. WE OPERATE IN A HIGHLY COMPETITIVE INDUSTRY. We compete with several other providers of seismic drilling, helicopter support, permitting and survey services. Competition among seismic contractors historically has been and will continue to be intense. Competitive factors have in recent years included price, crew experience, equipment availability, technological expertise and reputation for quality and dependability. Our revenues and earnings may be affected by the following factors: o changes in competitive prices; o fluctuations in the level of activity and major markets; o general economic conditions; and o governmental regulation. Additionally, certain of our competitors operate more crews than we do and have substantially greater financial and other resources. These larger and better financed operators could enjoy an advantage over us if the competitive environment for contract awards shifts to one characterized principally by intense price competition. SEASONALITY AND ADVERSE WEATHER CONDITIONS IN THE REGIONS IN WHICH WE OPERATE MAY ADVERSELY AFFECT OUR OPERATIONS. Our operations are directly affected by the weather conditions in the Gulf of Mexico. Due to seasonal differences in weather patterns, we may operate more days in the spring, summer and fall periods and less in the winter months. The seasonality of oil and gas industry activity in the Gulf Coast region also affects our operations and sales of equipment. Due to exposure to weather, we generally experience higher drilling activity in the spring, summer and fall months with the lowest activity in winter months, especially with respect to our operations in the mountainous regions of the Western United States. The rainy weather, hurricanes and other storms prevalent in the Gulf of Mexico and along the Gulf Coast throughout the year may also affect our operations. As a result, full-year results are not likely to be a direct multiple of any particular quarter or combination of quarters. WE ARE DEPENDENT ON KEY PERSONNEL. Our success depends on, among other things, the continued active participation of our executive officers and certain of our other key operating personnel. Our officers and personnel have extensive experience in the domestic and international oilfield supply industry. The loss of the services of any one of these persons could impact adversely our ability to implement our expansion strategy. WE MAY INCUR ADDITIONAL EXPENDITURES TO COMPLY WITH GOVERNMENTAL REGULATIONS. Our seismic and aviation operations are subject to extensive governmental regulation, violations of which may result in civil and criminal penalties, injunctions and cease and desist orders. These laws and regulations govern, among other things, operations in wetlands, the handling of explosives and the operation of commercial aircraft. Although our cost of compliance with such laws has to date been immaterial, such laws are changed frequently. Accordingly, it is impossible to predict the cost or impact of such laws on our future operations. We are also required by various governmental agencies to obtain certain permits, licenses and certificates. To date, we believe that we possess all permits, licenses and 5 certificates material to the operation of our business. The loss by us of any of the licenses required for our operation could have a material adverse effect on our operations. We depend on demand for our services from the oil and gas industry, and this demand may be affected by changing tax laws and oil and gas regulations. As a result, the adoption of laws that curtail oil and gas production in our areas of operation may adversely affect us. We cannot determine to what extent our operations may be affected by any new regulations or changes in existing regulations. FUTURE TECHNOLOGICAL ADVANCES COULD IMPAIR OPERATING ASSETS OR REQUIRE SUBSTANTIAL UNBUDGETED CAPITAL EXPENDITURES. We compete in providing services in a capital intensive business. The development of seismic data acquisition and processing equipment has been characterized by rapid technological advancements in recent years, and this trend may continue. Manufacturers of seismic equipment may develop new systems that have competitive advantages over systems now in use that could render our current equipment obsolete or require us to make significant unplanned capital expenditures to maintain our competitive position. Under such circumstances, there can be no assurance that we would be able to obtain necessary financing on favorable terms. WE DEPEND ON A FEW SIGNIFICANT CUSTOMERS. We derive a significant amount of our revenue from a small number of geophysical companies. Our inability to continue to perform services for a number of our large existing customers, if not offset by sales to new or other existing customers could have a material adverse effect on our business and operations. ONE SHAREHOLDER HAS SUBSTANTIAL CONTROL OVER OUR AFFAIRS. Prior to the sale of the shares to be sold by the selling shareholders pursuant to this prospectus, Advantage Capital Partners and its affiliates beneficially owned approximately 56.2% of our outstanding common stock. This percentage includes an aggregate of 538,687 shares of common stock owned by Advantage Capital Partners and its affiliates and an aggregate of 5,321,110 shares of our common stock that may be issued to Advantage Capital Partners and its affiliates upon conversion of 7,500 shares of our outstanding Series A Preferred Stock, 4,600 shares of our outstanding Series B Preferred Stock and 761,110 warrants. Additionally, two members of our board of directors are affiliates of Advantage Capital Partners. As a result, Advantage Capital Partners had the ability to substantially influence our management and affairs and all matters requiring shareholder approval, including the election of directors and approval of significant corporate transactions, such as a merger, consolidation or sale of substantially all of our assets. This may have the effect of delaying, deferring or preventing a change in control, or impeding a merger or consolidation. In November and December 2003, Advantage Capital Partners and its affiliates have sold or intend to sell an aggregate of 2,323,699 shares of our common stock on the Nasdaq National Market pursuant to Rule 144 at prices and terms then prevailing or at prices related to the then-current market price. If the selling shareholders sell those shares and all of the shares being offered by this prospectus, Advantage Capital Partners and its affiliates will beneficially own an aggregate of approximately 5.2% of our outstanding common stock. This percentage includes an aggregate of 761,110 shares of common stock to be issued upon the exercise of warrants issued at a price of $2.25 per share. Advantage Capital Partners has agreed to reduce its board representation from two members to one member effective with the next annual meeting of our shareholders. 6 WHERE YOU CAN FIND MORE INFORMATION We file annual, quarterly and current reports, proxy statements and other information with the Securities and Exchange Commission, or SEC.

Darcy Klug (337) 896-6664 7 THE COMPANY We are an oilfield supply company that specializes in providing an integrated range of onshore seismic drilling, permitting, survey and helicopter support services to geophysical companies operating in logistically difficult and environmentally sensitive terrain in the United States. Our primary market is the marsh, swamp, shallow water and contiguous dry land areas along the U.S. Gulf Coast (the "Transition Zone"), primarily in Louisiana and Texas where we are leading provider of seismic drilling support services. During the latter part of 1997, we commenced operations in the mountainous regions of the Western United States. We previously operated in Canada and South America but in 1999 we ceased these international operations pending improvements in the international marketplace. We own and operate a fleet of specialized seismic drilling and transportation equipment for use in the Transition Zone. We believe we are the only company that currently can both provide an integral range of seismic drilling, permitting, survey and helicopter support services in all of the varied terrain of the Transition Zone and simultaneously support operations for multiple, large-scale seismic projects. In February 2002, we acquired all of the assets of AirJac Drilling, a division of Veritas Land DGC. This acquisition created the largest domestic provider of seismic drilling services to geophysical companies. We also maintain a fleet of helicopters, including an inventory of aviation parts, turbine engines and other miscellaneous flight equipment used in providing aviation services to our customers. In November 2003, we acquired all of the outstanding stock of American Helicopters, Inc. and announced the internal expansion of our aviation fleet. We are a Louisiana corporation, and the mailing address of our executive offices is 4500 NE Evangeline Thwy., Carencro, Louisiana 70520. Our telephone number is (337) 896-6664.

The selling shareholders may sell all or part of their shares in one or more transactions at fixed prices, varying prices, prices at or related to the then-current market price or at negotiated prices. The selling shareholders will determine the specific offering price of the shares from time to time that, at that time, may be higher or lower than the market price of our common stock on the Nasdaq National Market. The selling shareholders and any underwriters, broker-dealers or agents participating in the distribution of the shares of our common stock may be deemed to be "underwriters" within the meaning of the Securities Act of 1933, and any profit from the sale of such shares by the selling shareholders and any compensation received by any underwriter, broker-dealer or agent may be deemed to be underwriting discounts under the Securities Act. The selling shareholders may agree to indemnify any underwriter, broker-dealer or agent that participates in transactions involving sales of the shares against certain liabilities, including liabilities arising under the Securities Act. Because selling shareholders may be deemed to be "underwriters" within the meaning of the Securities Act, the selling shareholders will be subject to the prospectus delivery requirements of the Securities Act. We have informed the selling shareholders that the anti-manipulative provisions of Regulation M promulgated under the Exchange Act may apply to their sales in the market. With certain exceptions, Regulation M precludes the selling shareholders, any affiliated purchasers, and any broker-dealer or other person who participates in such distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase any security which is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security. The method by which the selling shareholders, or their pledgees, donees, transferees or other successors in interest, may offer and sell their shares may include, but are not limited to, the following: o sales on the Nasdaq National Market, the over-the-counter market, or other securities exchange on which the common stock is listed at the time of sale, at prices and terms then prevailing or at prices related to the then-current market price; o sales in privately negotiated transactions; o sales for their own account pursuant to this prospectus; o through the writing of options, whether such options are listed on an options exchange or otherwise through the settlement of short sales; o cross or block trades in which broker-dealers will attempt to sell the shares as agent, but may position and resell a portion of the block as a principal in order to facilitate the transaction; o purchases by broker-dealers who then resell the shares for their own account; o brokerage transactions in which a broker solicits purchasers; o any combination of these methods of sale; and o any other method permitted pursuant to applicable law. 10 Any shares of common stock covered by this prospectus that qualify for sale under Rule 144 or Rule 144A of the Securities Act may be sold under Rule 144 or Rule 144A rather than under this prospectus. The shares of our common stock may be sold in some states only through registered or licensed brokers or dealers. In addition, in some states, the shares of our common stock may not be sold unless they have been registered or qualified for sale or the sale is entitled to an exemption from registration. The selling shareholders may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of our common stock in the course of hedging the positions they assume with selling shareholders. The selling shareholders may also enter into options or other transactions with broker-dealers or other financial institutions which require the delivery to such broker-dealer or other financial institution of the shares offered hereby, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). To the extent required by a particular offering, we will set forth in a prospectus supplement or, if appropriate, a post-effective amendment, the terms of such offering, including among other things, the number of shares of common stock to be sold, the public offering price, the names of any underwriters, dealers or agents and any applicable commissions or discounts. In addition, upon the company being notified by a selling shareholder that a donee or pledgee intends to sell more than 500 shares, a supplement to this prospectus will be filed. To our knowledge, there are currently no plans, arrangements or understandings between any selling shareholder and any underwriter, broker-dealer or agent regarding the sale of shares of our common stock by the selling shareholders. The selling shareholders will pay all fees, discounts and brokerage commissions in connection with any sales, including any fees to finders. We will pay all expenses of preparing and reproducing this prospectus, including expenses or compliance with state securities laws and filing fees with the SEC.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS. As permitted by Louisiana law, the Company's Composite Articles of Incorporation contain certain provisions eliminating the personal liability of the directors and officers to the Company and its shareholders for monetary damages for breaches of their fiduciary duties as directors or officers, except for (i) a breach of a director's or officer's duty of loyalty to the Company or to its shareholders, (ii) acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) dividends or stock repurchases or redemptions that are illegal under Louisiana law and (iv) any transaction from which he or she receives an improper personal benefit. In addition, the Amended and Restated Articles of Incorporation provide that if Louisiana law is amended to authorize the further elimination or limitation of the liability of a director or officer, then the liability of the directors or officers shall be eliminated or limited to the fullest extent permitted by Louisiana law, as amended. These provisions pertain only to breaches of duty by directors or officers in such capacities and limit liability only for breaches of fiduciary duties under Louisiana corporate law and not for violations of other laws such as the federal securities laws. The Company's By-laws require the Company to indemnify its directors and officers against certain expenses and costs, judgments, settlements and fines incurred in the defense of any claim, including any claim brought by or in the right of the Company, to which they were made parties by reason of being or having been directors and officers, subject to certain conditions and limitations. In addition, each of the Company's directors and executive officers has entered into an indemnity agreement with the Company, pursuant to which the Company has agreed under certain circumstances to purchase and maintain directors' and officers' liability insurance. The agreements also provide that the Company will indemnify the directors and executive officers against any costs and expenses, judgments, settlements and fines incurred in connection with any claim involving a director or executive officer by reason of his position as a director or executive officer that are in excess of the coverage provided by such insurance; provided that the director or executive officer meets certain standards of conduct. Under the indemnity agreements, the Company is not required to purchase and maintain directors' and officers' liability insurance if it is not reasonably available or, in the reasonable judgment of the Board of Directors, there is insufficient benefit to the Company from the insurance.

ITEM 17. UNDERTAKINGS. (a) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement to include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Company's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other that the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. II-2 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in Carencro, Louisiana, on December 18, 2003.
