Report of Independent Registered Public Accounting Firm

The Occidental Petroleum Corporation

Pension and Retirement Plan Administrative Committee:

We have audited the accompanying statements of net assets available for benefits of the Occidental Petroleum Corporation Savings Plan (the Plan) as of December 31, 2006 and 2005, and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2006 and 2005, and the changes in net assets available for benefits for the years then ended in conformity with U.S. generally accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of Schedule H, line 4i – schedule of assets (held at end of year) as of December 31, 2006 and Schedule H, line 4j – schedule of reportable transactions for the year ended December 31, 2006 are presented for purposes of additional analysis and are not a required part of the basic financial statements but are supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974, as amended (ERISA). These supplemental schedules are the responsibility of the Plan’s management. The supplemental schedules have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated, in all material respects, in relation to the basic financial statements taken as a whole.

SAVINGS PLAN

Notes to Financial Statements

December 31, 2006 and 2005

(1)	Description of the Plan
	The following description of the Occidental Petroleum Corporation Savings Plan (the Plan) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.
	*(a)*	*General*
		The Plan is a defined contribution plan generally available to certain employees of Occidental Petroleum Corporation (OPC, Oxy, or the Employer), a Delaware corporation, and participating subsidiaries (collectively, the Company). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA).
	*(b)*	*Plan Administration*
		The Plan is administered by the OPC Pension and Retirement Trust and Investment Committee (PARTAIC) as to investment decisions and by the OPC Pension and Retirement Plan Administrative Committee (PARPAC) as to all matters except investment decisions (these two committees are herein referred to collectively as the Committees). Members of the Committees are selected by the board of directors of OPC (the Board). The Committees have been given all powers necessary to carry out their respective duties, including, but not limited to, the power to administer and interpret the Plan and to answer all questions affecting eligibility of participants. The Bank of New York Trust Company (the Trustee) is the trustee and custodian of the trust fund, which holds all of the assets of the Plan.
	*(c)*	*Contributions*
		Participant Contributions – Each year, participants may contribute up to the maximum contribution percentage of compensation (as defined) to the Plan on a before- or after-tax basis, or in any combination thereof, subject to certain Internal Revenue Code (IRC) limitations. For 2006, the deferral percentage limits were 30.7% for non-Highly Compensated Employees (non-HCEs) and 14% for Highly Compensated Employees (HCEs). For 2005, the deferral percentage limits were 30.9% for non-HCEs and 14% for HCEs. Participants age 50 or older by the end of the Plan year were permitted to contribute before-tax catch-up contributions to the Plan up to $5,000 and $4,000 for the 2006 and 2005 Plan years, respectively.
		Employer Matching Contributions – For noncollectively bargained employees, the Company contributes 100% of a participant’s contribution up to the first 6% of eligible compensation. For collectively bargained employees, the Company contributes 50%, 65%, 75%, 90%, or 100%, as negotiated by their respective unions, of the first 6% of eligible compensation that a participant contributed to the Plan. All Employer contributions are invested in the Occidental Petroleum Corporation Common Stock Fund (the Oxy Stock Fund).

December 31, 2006 and 2005

	*(d)*	*Participant Accounts*
		Each participant’s account is credited with the participant’s elected contribution, the Employer’s respective matching contribution, and allocations of Plan earnings, and charged with an allocation of Plan investment losses and Trustee fees. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.
	*(e)*	*Vesting*
		Participants are vested immediately in their contributions plus actual earnings thereon. Effective June 1, 2002, participants became 100% vested in dividends credited to their balance in the Company Matching Contribution Account under the Oxy Stock Fund on or after June 1, 2002. Vesting in the Company’s contribution portion of their accounts is based on years of continuous service. Generally, a participant is 20% vested for each full year of service and is 100% vested after five years of vesting service.
	*(f)*	*Participant Loans*
		Participants may borrow from their fund accounts a minimum of $1,000 up to a maximum equal to the lesser of: (i) $50,000 reduced by the highest outstanding principal loan balance during the preceding 12 months, (ii) 50% of their account balance, or (iii) a loan amount that would require monthly payroll deductions for repayment not greater than 25% of the participant’s monthly base compensation. Loan terms range from one to five years for general purpose loans and six to ten years for primary residence loans. The loans are secured by the balance in the participant’s account and bear interest at a fixed rate equal to the Western Federal Credit Union’s loan rate for a loan secured by a member’s deposit account at the time the loan is approved. Interest rates ranged from 2% to 12% on loans outstanding as of December 31, 2006. Principal and interest are paid ratably through monthly payroll deductions.
	*(g)*	*Distributions*
		Generally, on termination of service for any reason other than death, participants with an account balance greater than $5,000 may elect to receive the vested portion of their account under one of the following distribution options: (i) one lump-sum payment, (ii) straight-life annuity, (iii) ten-year term certain annuity, (iv) joint and survivor annuity, (v) partial cash distribution, or (vi) deferral of payment with certain restrictions. Upon termination of service due to death, the beneficiary may elect to receive the vested interest in the form of (i), (ii), (iii), or (vi) only. A participant whose vested account balance is $5,000 or less may receive distributions only under options (i), (v), or (vi). Participants may elect to receive distributions from their account balance in the Oxy Stock Fund in cash or in shares of OPC common stock.

December 31, 2006 and 2005

	*(h)*	*Forfeited Accounts*
		Forfeited nonvested accounts are used to pay reasonable costs of administering the Plan and reduce employer contributions. During 2006 and 2005, employer contributions were reduced by approximately $638,000 and $402,000, respectively, from forfeited nonvested accounts. At December 31, 2006 and 2005, forfeited nonvested accounts totaled $222,581 and $20,405, respectively. These accounts will be used to reduce future contributions.
	*(i)*	*Plan Amendments*
		Effective July 1, 2006, the Plan’s definition of eligible compensation was amended to include base salary or wages received during paid leaves of absence and periodic notice pay, but not single sum notice payments or any severance pay payments.
(2)	Summary of Significant Accounting Policies
	*(a)*	*Basis of Accounting*
		The financial statements of the Plan are prepared under the accrual method of accounting. Certain reclassifications have been made to the 2005 financial statements to be consistent with the current year presentation.
	*(b)*	*Use of Estimates*
		The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.
	*(c)*	*New Accounting Pronouncement*
		As described in Financial Accounting Standards Board Staff Position, FSP AAG INV-1 and SOP 94-4-1, Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined Contribution Health and Welfare and Pension Plans (the FSP), investment contracts held by a defined contribution plan are required to be reported at fair value. However, contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the plan. As required by the FSP, the statement of net assets available for benefits presents the fair value of the investment contracts from fair value to contract value. Prior year balances have been reclassified accordingly. The statement of changes in net assets available for benefits is prepared on a contract value basis.

	*(d)*	*Investment Valuation and Income Recognition*
		The Plan’s investments are stated at fair value. The common/collective trust is valued by the issuer based on quoted prices of the underlying securities, if available. Shares of mutual funds are valued at the net asset value of shares held by the Plan at year-end. Participant loans are valued at cost, which approximates fair value.
		Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on an accrual basis. Dividends are recorded on the ex-dividend date.
	*(e)*	*Payment of Benefits*
		Benefits are recorded when paid.

The Plan participated in the Trustee’s Securities Lending Program for its U.S. securities held in custody at the Trustee. These securities are loaned by the Trustee to third-party broker-dealers in exchange for collateral (primarily cash), in compliance with Department of Labor collateral requirements. For U.S. securities, the collateral is at least 102% of the fair value of the borrowed securities. The cash received as collateral is invested in the Trustee’s Institutional Cash Reserves Fund, which is a money market fund. The fair value of securities loaned was approximately $14,982,000 and $9,364,000 at

The Plan and the Trustee each receive a percentage of net income derived from securities lending activities based on the types of securities. Income earned during 2006 and 2005 was approximately $2,000 each year, net of bank fees of approximately $3,000 and $2,000, respectively. This income is included in investment income as interest in the accompanying statements of changes in net assets available for benefits.

Plan Interest in Master Trust Accounts

The Plan invests in three Master Trust Investment Accounts (MTIA), a guaranteed investment contract fund managed by Invesco (GIC MTIA, also known as the Invesco Stable Value Fund), a convertible bond fund managed by Advent Capital Management (Advent MTIA), and a small cap equity fund managed by Alliance Bernstein Institutional Investment Management (Bernstein MTIA). The Plan and the OPC Retirement Plan each own an undivided interest in the GIC MTIA. The Plan and the OPC Master Retirement Trust (MRT) each own an undivided interest in the Advent MTIA and Bernstein MTIA.

	$	24,083		21,293

The Plan’s interest in the net change (including investment income, additions, and deductions) in the GIC MTIA for the years ended December 31, 2006 and 2005 were approximately $13,060,000 and $10,662,000, respectively. The GICs are valued at fair value because they are fully benefit responsive. Participants may ordinarily direct the withdrawal or transfer of all or a portion of their investment at contract value.

Withdrawals resulting from events initiated by the Company, such as Plan termination, are not typically considered participant-initiated transactions. With such an event, some of the contracts contain contingencies that could lead to withdrawal penalties. The Committees are not aware of any such event being contemplated at this time.

Contract value for the synthetic GICs is determined based on the fair value of the assets underlying the synthetic GICs. The difference between the fair value of the assets underlying the synthetic GICs and the contract value of the GICs is the value of the “wrapper” contract issued by a third party. The fair value for GICs varies based on the type of contract held (e.g., security-backed investments and general account

9	(Continued)

OCCIDENTAL PETROLEUM CORPORATION

SAVINGS PLAN

Notes to Financial Statements

December 31, 2006 and 2005

investments). Fair value of the general account investment type GICs is derived by comparing the contract value, on a duration basis, to the yield curve. Fair value of the nonparticipating synthetic GICs is determined by comparing each contract, on a duration basis, to a Treasury yield curve at year-end plus 40 basis points. Fair value for security-backed investment contracts was derived from outside sources, based on the type of investment held.

GICs provide a fixed crediting interest rate, and a financially responsible entity guarantees liquidity at contract value prior to maturity for any and all participant-initiated benefit withdrawals, loans, or transfers arising under the terms of the respective participating Plan, which allows access for all participants.

Synthetic GICs operate similarly to a separate account guaranteed investment contract, except that the assets are placed in a trust with ownership by GIC MTIA rather than a separate account of the issuer and a financially responsible third party issues a wrapper contract that provides that participants can, and must, execute Plan transactions at contract value.

The wrapper contract is valued at the difference between the fair value of the underlying assets and the contract value attributable by the wrapper to such assets. When considered together, the underlying assets and the wrapper contract are reported at the wrapper contract value because participants are guaranteed a return of principal and accrued interest.

During 2006 and 2005, the average yield earned on amounts invested in the GICs was 4.92% and 4.72%, respectively. As of December 31, 2006 and 2005, the average crediting interest rate on such contracts was 5.07% and 4.74%, respectively. There were no valuation reserves recorded to adjust contract amounts during the Plan years. Crediting rate resets are applied to specific investment contracts, as determined at the time of purchase. The reset values for security-backed investment rates are a function of contract value, market value, yield, and duration. General account investment rates are based on a predetermined index rate of return plus a fixed-basis point spread.

The Plan’s interest in the net change (including investment income, additions, and deductions) in the Advent MTIA for the years ended December 31, 2006 and 2005 were approximately $391,000 and $94,000, respectively.

The Advent MTIA participated in the Trustee’s Securities Lending Program for its U.S. securities held in custody at the Trustee to provide incremental income in 2006 and 2005. These securities are loaned by the Trustee to third-party broker-dealers in exchange for collateral (primarily cash), in compliance with Department of Labor collateral requirements. For U.S. securities, the collateral is at least 102% of the fair value of the borrowed securities. The cash received as collateral is invested in the Trustee’s Institutional Cash Reserves Fund, which is a money market fund. The fair value of securities loaned was approximately $5,700,000 and $5,226,000 at December 31, 2006 and 2005, respectively. Cash collateral of approximately $5,819,000 and $5,410,000 was held at December 31, 2006 and 2005, respectively, with an offsetting liability.

The Advent MTIA and the Trustee each receive a percentage of net income derived from securities lending activities based on the types of securities. Income earned during 2006 and 2005 was approximately $6,000 and $10,000, respectively, which is included in interest and dividends net of bank fees of approximately $6,000 and $13,000, respectively.

Notes to Financial Statements

December 31, 2006 and 2005

	The Plan’s interest in the net change (including investment income, additions, and deductions) in the Bernstein MTIA for the years ended December 31, 2006 and 2005 were $9,683,000 and $4,243,000, respectively.
	The Bernstein MTIA participated in the Trustee’s Securities Lending Program for its U.S. securities held in custody at the Trustee to provide incremental income in 2006 and 2005. These securities are loaned by the Trustee to third-party broker-dealers in exchange for collateral (primarily cash), in compliance with Department of Labor collateral requirements. For U.S. securities, the collateral is at least 102% of the fair value of the borrowed securities. The cash received as collateral is invested in the Trustee’s Institutional Cash Reserves Fund, which is a money market fund. The fair value of securities loaned was approximately $27,034,000 and $26,394,000 at December 31, 2006 and 2005, respectively. Cash collateral of approximately $27,807,000 and $27,321,000 was held at December 31, 2006 and 2005, respectively, with an offsetting liability.
	The Bernstein MTIA and the Trustee each receive a percentage of net income derived from securities lending activities based on the types of securities. Income earned during 2006 and 2005 was approximately $21,000 and $14,000, respectively, net of bank fees of approximately $24,000 and $16,000, respectively.
(6)	Related-Party Transactions
	The Trustee and OPC are parties in interest as defined by ERISA. The Trustee invests certain Plan assets in its Collective Short-Term Investment Fund and the Oxy Stock Fund. Such transactions qualify as party-in-interest transactions permitted by the Department of Labor regulations. The Plan paid about $282,000 and $310,000 to the Trustee for the years ended December 31, 2006 and 2005, respectively.
(7)	Plan Termination
	Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants would become 100% vested in their Employer contributions.
(8)	Tax Status
	The Internal Revenue Service has determined and informed the Company, by a letter dated June 14, 2004, that the Plan and related trust are designed in accordance with applicable sections of the IRC. Although the Plan has been amended since receiving the determination letter, the Committees, using their judgment and the advice of their advisors, believe that the Plan is currently designed and operating in a manner that preserves its tax-qualified status.
(9)	Risks and Uncertainties
	The Plan invests in various types of investment securities, including mutual funds, actively managed funds, and the Oxy Stock Fund. Investment securities are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participant’s account balance and the amounts reported in the statements of net assets available for benefits.

	Additionally, some mutual funds invest in the securities of foreign companies, which involve special risks and considerations not typically associated with investing in U.S. companies. These risks include devaluation of currencies, less reliable information about issuers, different securities transaction clearance and settlement practices, and possible adverse political and economic developments. Moreover, securities of many foreign companies and their markets may be less liquid and their prices more volatile than similar types of securities of comparable U.S. companies.
	Derivative financial instruments are used by the Plan’s equity and fixed-income investment managers to remain fully invested in the asset class and to hedge currency risk. Leveraging of the Plan assets and speculation are prohibited.
	As of December 31, 2006 and 2005, approximately 42% and 44%, respectively, of total Plan investments were invested in Oxy stock.
(10)	Reconciliation of the Financial Statements to the Form 5500
