2.50% Convertible Senior Notes Due 2026

This document supplements our prospectus dated August 14, 2006, as previously supplemented by the prospectus supplements dated September 1, 2006, September 28, 2006, November 8, 2006 and March 2, 2007 relating to $500,000,000 aggregate principal amount of our 2.50% convertible senior notes due 2026 and the common stock issuable upon conversion of the notes. You should read this prospectus supplement in conjunction with the accompanying prospectus, which is to be delivered by the selling securityholders named below to prospective purchasers. The information in this prospectus supplement supercedes the information set forth under the heading “Selling Securityholders” in the prospectus and the prospectus supplements dated September 1, 2006, September 28, 2006, November 8, 2006 and March 2, 2007.

Our common stock is traded on the New York Stock Exchange under the symbol “CAM.” On September 4, 2007, the last reported sale price of our common stock was $84.66 per share.

Investing in the notes and our common stock issuable upon their conversion involves certain risks. See “Risk Factors” beginning on page 8 of the accompanying prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus supplement or the accompanying prospectus. Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is September 5, 2007.

SELLING SECURITYHOLDERS

The following table sets forth recent information about the principal amount of notes and the number of shares of common stock issuable upon conversion of the notes that may be offered for each selling securityholder’s account pursuant to this prospectus, in each case to the extent known to us as of the date of this prospectus supplement. The number of shares of common stock shown in the table below assumes conversion of the full amount of notes held by each holder at the initial conversion rate of 14.1328 shares per $1,000 principal amount of notes. This conversion rate is subject to adjustment as described under “Description of the Notes—Conversion Rights.” Accordingly, the number of shares of common stock issuable upon conversion of the notes may increase or decrease from time to time. Unless set forth below, to our knowledge none of the selling securityholders has had a material relationship with us or any of our predecessors or affiliates within the past three years.

The information in the following table set forth below supercedes in its entirety the information in the table under the caption “Selling Securityholders” in the accompanying prospectus dated as of August 14, 2006, and the information in the table under the caption “Selling Securityholders” in the prospectus supplements dated September 1, 2006, September 28, 2006, November 8, 2006 and March 2, 2007.

(*) Less than 1%.

(1) This prospectus may be used for the resale of a maximum of $500 million principal amount of notes. However, the information provided to us by the selling securityholders listed in this table indicates that the selling securityholders beneficially own more than $500 million aggregate principal amount of the notes. Although we make no representation as to the reasons for this inconsistency, we believe it is due to transactions in the notes since the dates the respective selling securityholders provided information to us.

(2) The percentage of notes outstanding is based on the $500 million principal amount of notes originally outstanding. Beneficial ownership is determined in accordance with SEC rules and includes voting or investment power with respect to the securities.

(3) Includes shares of common stock issuable upon conversion of the notes, assuming a conversion rate of 14.1328 shares per $1,000 principal amount of notes and a cash payment in lieu of any fractional share. The conversion rate is subject to

adjustment as described under “Description of the Notes—Conversion of Notes.” No holder of notes would beneficially own 1% or more of the issued and outstanding common stock upon conversion of its notes assuming a conversion rate of 14.1328 shares of common stock per $1,000 principal amount of notes.

(4) Assumes that any other holders of notes or any future transferee from any holder does not beneficially own any common stock other than common stock into which the notes are convertible at the conversion rate of 14.1328 shares per $1,000 principal amount of the notes.

(5) Any selling securityholder that is a broker-dealer may be deemed to be an underwriter with respect to the securities it sells pursuant to the prospectus. During the past three years, Morgan Stanley & Co. Incorporated and/or its affiliates have performed investment banking services for us.

Information concerning other selling securityholders of the notes will be set forth in additional prospectus supplements from time to time, if and when necessary. Additional selling securityholders not named in this prospectus supplement will not be able to use this prospectus for resales until they are named in the selling securityholder table by prospectus supplement or post-effective amendment to the registration statement of which this prospectus forms a part. Successors of identified selling securityholders, including without limitation their transferees, pledgees and donees or their successors, will not be able to use this prospectus for resales until they are named in the selling securityholder table by prospectus supplement or post-effective amendment.

The above table has been prepared based upon information furnished to us by the selling securityholders. The selling securityholders identified above may have sold, transferred or otherwise disposed of some or all of their notes in transactions exempt from the registration requirements of the Securities Act since the dates on which they provided us information. Information concerning the selling securityholders may change from time to time and, if necessary, we will supplement this prospectus accordingly. The selling securityholders may offer some or all of their notes or common stock pursuant to the offering contemplated by this prospectus. Additionally, the conversion ratio of the notes is subject to adjustment and, therefore, the number of shares of common stock issuable upon conversion of the notes may increase or decrease. Accordingly, we cannot give an estimate as to the amount of the notes or common stock issuable upon conversion of the notes that will be held by the selling securityholders upon the termination of this offering.
