Post-Effective Amendment No. 1 to

REGISTRATION STATEMENT
Under
THE SECURITIES ACT OF 1933

CHEVRONTEXACO CORPORATION

CHEVRON CORPORATION 1998 BROAD-BASED NONQUALIFIED STOCK OPTION
PROGRAM FOR U.S. DOLLAR PAYROLL EMPLOYEES

CALCULATION OF REGISTRATION FEE

     The Registration Statement shall become effective upon filing in accordance with Rule 462 under the Securities Act of 1933.

The Registrant has previously registered 4,200,000 shares of its Common Stock, par value $.75 per share, previously reserved for issuance under the Chevron Corporation 1998 Broad-Based Nonqualified Stock Option Program for U.S. Dollar Payroll Employees (the “Plan”) under currently effective Registration No. 333-46261 filed on February 13, 1998 (the “Registration Statement”).

As a result of a 2-for-1 stock split (the “Stock Split”) of the Common Stock of the Registrant in the form of a stock dividend distributed on September 10, 2004 (the “Distribution Date”) of one share of Common Stock for each share of Common Stock issued and outstanding on the record date of August 19, 2004, the 2,397,025 shares of Common Stock that are registered under the Registration Statement and not yet issued under the Plan as of the Distribution Date have been adjusted and increased by a ratio of 2-for-1, in order to account for the Stock Split and adjust the number of shares reserved and available for issuance pursuant to the Plan after the Distribution Date. Pursuant to Rule 416 under the Securities Act of 1933, the Registration Statement is deemed to cover these additional shares resulting from the Stock Split and the Registration Statement is hereby being amended to reflect the increase in the amount of shares of Common Stock registered.

This Post-Effective Amendment No. 1 affects only those provisions of the Registration Statement specifically restated herein. All other provisions of the Registration Statement remain unchanged.
