USE OF PROCEEDS We will not receive any proceeds from sales of common stock by the selling holder. THE SELLING HOLDER This prospectus covers the offer and sale by Dow Financial Holdings Inc., the selling holder, of up to 15,153,018 shares of our common stock. The shares were purchased by Dow Financial Holdings Inc. on December , 1999 for $29.6723 per share upon exercise of a warrant held by Dow Financial Holdings Inc. We originally issued the warrant entitling the holder to purchase 7,500,000 shares of our common stock in connection with our acquisition in 1992 of various companies that were owned 50% by Schlumberger entities and 50% by Dow entities prior to that transaction. As a result of a two-for-one split of our common stock and various transactions, the warrant entitled Dow Financial Holdings Inc. to purchase 15,153,018 shares of our common stock. Number of shares of common stock owned by the selling holder Number of shares of common prior to the offering stock offered -------------------------------- -------------------------- 15,153,018 15,153,018 The selling holder may sell up to all of the shares of the common stock shown above under the heading "Number of shares of common stock offered" pursuant to this prospectus in one or more transactions from time to time as described below under "Plan of Distribution." However, the selling holder is not obligated to sell any of the shares of common stock offered by this prospectus. PLAN OF DISTRIBUTION The selling holder may offer and sell the shares of common stock offered by this prospectus from time to time in one or more of the following transactions: . through the New York Stock Exchange or any other securities exchange that quotes the common stock . in the over-the-counter market . in transactions other than on those exchanges or in the over-the-counter market (including negotiated transactions and other private transactions) . in short sales of the common stock, in transactions to cover short sales or otherwise in connection with short sales . by pledge to secure debts and other obligations or on foreclosure of a pledge . in a combination of any of the above transactions The selling holder may sell its shares at market prices prevailing at the time of sale, at prices related to the prevailing market prices, at negotiated prices or at fixed prices. The transactions listed above may include block transactions. The selling holder may use broker-dealers to sell its shares or may sell its shares to broker-dealers acting as principals. If this happens, broker-dealers will either receive discounts or commissions from the selling holder, or they will receive commissions from purchasers of shares for whom they acted as agents, or both. If a broker-dealer purchases shares as a principal, it may resell the shares for its own account under this prospectus. We have informed the selling holder that the anti-manipulation provisions of Regulation M under the Securities Exchange Act of 1934 may apply to its sales of common stock. 4

The selling holder and any agent, broker or dealer that participates in sales of common stock offered by this prospectus may be deemed "underwriters" under the Securities Act of 1933, and any commissions or other consideration received by any agent, broker or dealer may be considered underwriting discounts or commissions under the Securities Act. We have agreed to indemnify the selling holder against certain liabilities arising under the Securities Act of 1933 from sales of common stock. The selling holder may agree to indemnify any agent, broker or dealer that participates in sales of common stock or warrants against liabilities arising under the Securities Act of 1933 from sales of common stock. Instead of selling common stock under this prospectus, the selling holder may sell common stock in compliance with the provisions of Rule 144 under the Securities Act of 1933, if available. The term "selling holder" also includes persons who obtain common stock from the selling holder in a distribution or dividend of assets by an entity to its equity holders. 5

DESCRIPTION OF CAPITAL STOCK The following descriptions provide a summary of our capital stock. Authorized, Issued and Treasury Shares We are authorized to issue 1,000,000,000 shares of common stock, par value $0.01 per share. On November 30, 1999, 667,054,806 shares were issued; 550,433,691 shares were outstanding; and 116,621,115 shares were held by us as treasury stock. In addition, we are authorized to issue, with some limitations with respect to voting rights, liquidation and dividend preferences, 200,000,000 shares of cumulative preferred stock, par value $0.01 per share, which may be issued in one or more separate series. If issued, the preferred stock may contain provisions allowing it to be converted into common stock under terms and conditions specified by our board of directors. No shares of preferred stock have been issued as of the date of this prospectus. Dividend Rights All outstanding shares of our common stock (i.e., shares not held by us or our subsidiaries) are entitled to participate equally and receive dividends which may be paid out of available profits of the preceding fiscal year or years. All accumulated and unpaid dividends payable on preferred stock (if issued and outstanding) must be paid prior to the payment of any dividends on common stock. The amount of dividends payable with respect to any fiscal year is determined by the stockholders at the annual general meeting held within nine months of such fiscal year following such fiscal year, except that our board of directors may declare interim dividends. Voting Rights Each holder of shares of common stock is entitled to one vote for each share registered in that holder's name. Voting rights may be exercised in person or by proxy. No action to amend our articles of incorporation or to sell all or substantially all of our assets or to dissolve us can be taken except upon the authorization of the holders of at least a majority of the outstanding shares eligible to vote. In addition, holders of preferred stock (if issued and outstanding) would have additional rights to vote as a class on certain amendments to our articles of incorporation that would adversely affect the preferred stock. Any other action requiring the approval of the stockholders may be authorized by a majority of the votes cast at any meeting at which a quorum is present, except that, if a quorum is not present at any meeting, a second meeting may be called, to be held within two months, at which second meeting, despite the absence of a quorum, valid resolutions may be adopted with respect to any matter stated in the notice of the original meeting and of the second meeting. A quorum consists of not less than 50% of the shares outstanding and eligible to vote. Our board of directors is authorized to effect reorganizations or rearrangements of our corporate structure or that of our subsidiaries without the vote of stockholders if such reorganization or rearrangement does not result in any diminution of the beneficial interest of the stockholders in our assets. The board of directors may change our corporate domicile from the Netherlands Antilles to another jurisdiction without the necessity of any stockholder action or approval. Preemptive and Other Rights The shares of our common stock do not carry any preemptive or conversion rights, and there are no redemption provisions with respect to the common stock. The shares of preferred stock (if issued and outstanding) would not carry any preemptive rights, but our board of directors could specify conversion rights, redemption provisions and (within limits) liquidation preferences with respect to one or more series of preferred stock. We may for our own account purchase shares of common stock so long as at least one-fifth of our authorized capital stock remains outstanding with other holders. In the event of liquidation, each share of common stock is entitled to equal rights after satisfaction of any preferred stock liquidation preference. Listing; Transfer Agents and Registrars Our common stock is listed for trading on the New York, London, Paris, Amsterdam and Swiss stock exchanges.

ITEM 15. Indemnification of Directors and Officers Article IX, Section 7 of our Articles of Incorporation and Article V of our By-Laws provide that: We have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of Schlumberger) by reason of the fact that he or she is or was a director, officer, employee or agent of Schlumberger, or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise or entity, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of Schlumberger, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent does not, of itself, create a presumption that the person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to our best interests, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful. We have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of Schlumberger to procure a judgment in our favor by reason of the fact that he or she is or was a director, officer, employee or agent of Schlumberger, or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise or entity against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with the defense or settlement of such action or suit if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to our best interests and except that no indemnification may be made in respect of any claim, issue or matter as to which that person has been finally adjudged to be liable to us for improper conduct unless and only to the extent that the court in which that action or suit was brought or any other court having appropriate jurisdiction determines upon application that, despite the adjudication of liability, but in view of all the circumstances of the case, that person is fairly and reasonably entitled to indemnity for those expenses, judgments, fines and amounts paid in settlement which the court in which the action or suit was brought or such other court having appropriate jurisdiction deems proper. II-1

To the extent that one of our directors, officers, employees or agents has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in the two preceding paragraphs, or in defense of any claim, issue or matter therein, we will indemnify that person against expenses (including attorneys' fees) actually and reasonably incurred by him or her in connection therewith. Any indemnification under the first two paragraphs in this item (unless ordered by a court) may be made by us only as authorized by contract approved, or by-laws, resolution or other action adopted or taken, by the Board of Directors or by the stockholders. Expenses incurred in defending a civil or criminal action, suit or proceeding will be paid by us in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the director, officer, employee or agent to repay such amount if it is ultimately determined that he or she is not entitled to be indemnified by us as authorized by Article V of the By-Laws or Article IX, Section 7 of the Articles of Incorporation. The indemnification and advancement of expenses provided by or granted pursuant to the other Sections of Article V of the By-Laws and Article IX, Section 7 of the Articles of Incorporation are not exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any law, by-law, agreement, vote of stockholders or disinterested directors, or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office, and continues as to a person who has ceased to be a director, officer, employee or agent and inures to the benefit of the heirs, executors and administrators of that person. We have the power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of Schlumberger, or is or was serving at our request in such a capacity for another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against that person and incurred by that person in any of those capacities or arising out of his status as such, whether or not we may indemnify him or her against such liability under the provisions of Article V of the By-Laws or Article IX, Section 7 of the Articles of Incorporation. For purposes of Article V of the By-Laws and Article IX, Section 7 of the Articles of Incorporation, reference to us or Schlumberger includes, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or Merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, stands in the same position under the provisions of Article V of the By-Laws and Article IX, Section 7 of the Articles of Incorporation with respect to the resulting or surviving corporation as he would have with respect to such constituent corporation if its separate existence had continued. In addition, we maintain directors' and officers' liability insurance which insures against certain liabilities that the officers and directors of Schlumberger may incur in such capacities. II-2

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: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) of the Securities Act if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; and (iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement is on Form S-3 or Form S-8 and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the 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. II-3

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the Registration Statement 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. (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 Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than 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 Act and will be governed by the final adjudication of such issue. II-4
