Chevron Issues Interim Update for Second Quarter 2008

In its interim update for the second quarter 2008, Chevron Corporation (NYSE:CVX) reported that upstream earnings are expected to benefit from an increase in prices for crude oil and natural gas while downstream earnings are expected to be significantly lower than the first quarter. Additionally, "all other” charges are anticipated to be substantially higher compared with the first quarter. Basis for Comparison in Interim Update The interim update contains certain industry and company operating data for the second quarter 2008. The production volumes, realizations, margins and certain other items in the report are based on a portion of the quarter and are not necessarily indicative of Chevron's quarterly results to be reported on August 1, 2008. The reader should not place undue reliance on this data. Unless noted otherwise, all commentary is based on two months of the second quarter 2008 vs. full first quarter 2008 results. UPSTREAM - EXPLORATION AND PRODUCTION   The table that follows includes information on production and price indicators for crude oil and natural gas for specific markets. Actual realizations may vary from indicative pricing due to quality and location differentials and the effect of pricing lags. International earnings are driven by actual liftings, which may differ from production due to the timing of cargoes and other factors.       2007   2008 2Q   3Q   4Q   1Q   2Q thruMay   2Q thruJun U.S. Upstream           Net Production: Liquids MBD 468 458 451 437 439 n/a Natural Gas MMCFD 1,703 1,695 1,675 1,666 1,585 n/a Total Oil-Equivalent MBOED 752 741 730 715 702 n/a   Pricing: Avg.

The increase in crude oil prices during this period reduced the company’s production under cost-recovery and variable-royalty provisions of certain international production contracts. U.S. natural gas production decreased nearly 5 percent primarily due to operational downtime and natural field declines. International natural gas production decreased about 3 percent, reflecting the absence of the first quarter’s favorable unitization adjustment in Indonesia. U.S. crude oil realizations rose more than $19 per barrel to $109.19. International liquids realizations averaged $106.14 per barrel, up about $20 per barrel from the first quarter. U.S. natural gas realizations increased $1.87 to $9.42 per thousand cubic feet, while international natural gas realizations rose $0.63 to $5.46 per thousand cubic feet. DOWNSTREAM – REFINING, MARKETING AND TRANSPORTATION   The table that follows includes industry benchmark indicators for refining and marketing margins. Actual margins realized by the company may differ significantly due to location and product mix effects, planned and unplanned shutdown activity and other company-specific and operational factors.       2007   2008 2Q   3Q   4Q   1Q   2Q thruMay   2Q thruJun Downstream           Market Indicators: $/Bbl Refining Margins US West Coast – Blended 5-3-1-1 36.32 19.57 22.49 20.39 26.41 27.70 US Gulf Coast – Maya 5-3-1-1 34.61 25.16 23.42 26.35 36.62 35.89 Singapore – Dubai 3-1-1-1 8.87 5.84 7.33 6.64 9.29 8.73 N.W.

Marketing margins were mixed. Asia-Pacific/Middle East/Africa marketing margins declined between the first quarter and the first two months of the second quarter. U.S. marketing indicator margins were lower, particularly on the West Coast, comparing the first quarter to the full second quarter. Despite improved refining indicator margins, earnings for the downstream segment in the full second quarter are expected to decline well in excess of $500 million compared with the first quarter. The projected decline in downstream earnings between sequential quarters reflects the following factors: Timing effects associated with the increase in crude prices. From the start to the end of the second quarter, WTI crude prices increased $39 per barrel. This rapid rise in crude prices led to lower second quarter earnings, primarily due to impacts on provisionally priced crudes and derivative positions under mark-to-market accounting. The effects of planned and unplanned refinery downtime. The company did not fully benefit from higher U.S. Gulf Coast margins due to planned downtime at the Pascagoula, Mississippi refinery. The downtime was associated with scheduled maintenance of the refinery’s No. 1 crude unit for 51 days and the coker for 63 days during the second quarter. The crude unit resumed operations in mid-May and the coker in early July. In addition, the company’s refinery at Pembroke, United Kingdom experienced unplanned downtime in late April. The refinery resumed full operations in late May. Higher operating expenses, including fuel and costs associated with the refinery shutdowns. U.S. refinery daily crude-input volumes decreased primarily due to scheduled maintenance of the Pascagoula Refinery’s No. 1 crude unit. Outside the U.S., refinery input volumes fell slightly due to the unplanned shutdown at the Pembroke refinery, partially offset by the completion of a planned shutdown at the company’s refinery in South Africa.

CMAI and Purvin & Gertz make no guarantee or warranty and assume no liability as to their use. In the Chemicals segment, earnings for the full second quarter are expected to be roughly unchanged from the first quarter. The absence of the first quarter’s provision for environmental remediation is projected to be largely offset by increased plant maintenance activity. ALL OTHER The company’s guidance for the quarterly net after-tax charges related to corporate and other activities is between $250 million and $300 million. Due to the potential for irregularly occurring accruals related to income taxes, pension settlements and other matters, actual results may significantly differ from the guidance range. For the full second quarter, net charges are expected to be significantly higher than the standard guidance range, primarily reflecting charges for environmental remediation, along with other corporate items.
