Item 1.      Security and Issuer

              This Amendment No. 3 (this “Amendment”) amends and supplements Amendment No. 2 to Schedule 13D (the “Schedule 13D”) filed with the Securities and Exchange Commission (the “SEC”) on April 16, 2009, by Steelhead Partners, LLC (“Steelhead”), Steelhead Offshore Partners, LLC (“Steelhead Offshore”), Steelhead Navigator Master, L.P. (“Navigator”), James Michael Johnston and Brian Katz Klein, relating to shares of common stock, no par value per share (the “Common Stock”), of Canadian Superior Energy Inc. (the “Issuer”). Unless expressly amended or supplemented by this Amendment, all information previously included in the Schedule 13D remains in effect.

Item 5.      Interest in Securities of the Issuer

              Item 5(a) of the Schedule 13D is amended and restated in its entirety as follows:

              (a) Navigator beneficially owns 14,836,315 shares of Common Stock (which includes 3,500,000 shares issuable upon exercise in full of warrants held by Navigator). The percentage of Common Stock beneficially owned by Navigator is 8.6%.

              Steelhead Offshore, as the general partner of Navigator, Steelhead, as the sole member of Steelhead Offshore and as the investment manager of Navigator and certain client accounts, and Mr. Johnston and Mr. Klein, as the member-managers of Steelhead, may be deemed to beneficially own the shares owned by Navigator and/or such client accounts in that they may be deemed to have the power to direct the voting or disposition of the shares. Neither the filing of this Schedule nor any of its contents shall be deemed to constitute an admission that any of Steelhead Offshore, Steelhead, Mr. Johnston or Mr. Klein is, for any other purpose, the beneficial owner of any such securities, and Steelhead Offshore, Steelhead, Mr. Johnston and Mr. Klein disclaim beneficial ownership as to such securities except to the extent of their respective pecuniary interests therein. For the purposes of this Schedule, Steelhead, Mr. Johnston and Mr. Klein beneficially own 15,186,315 shares of Common Stock (which includes all of the Issuer’s shares beneficially owned by Navigator), and the percentage of Common Stock beneficially owned by such reporting persons is 8.8%.

              The calculation of percentage of beneficial ownership in Item 13 of pages 2 - 6 was derived from the Issuer’s Annual Report on Form 40-F filed with the SEC on May 1, 2009, in which the Issuer stated that the number of shares of its Common Stock outstanding as of December 31, 2008 was 168,644,716 shares.

              Item 5(c) is amended and supplemented as follows:

(c)          Since the most recent Schedule 13D filing, the reporting persons sold the following shares of Common Stock in the open market:

Entity  Trade Date  Shares (#)  Price/Share ($) 
Navigator  04-21-09  1,000,000  0.4687 
Navigator  04-21-09  500,000  0.4691
