The following accounted for the decline in oil and gas earnings between these quarters
Analyst
Lower worldwide oil price realizations offset by higher gas realizations resulted in a decrease of $66 million of earnings over the same period last year. The average price of West Texas Intermediate oil for the second quarter 2007 was $65.05 per barrel which was $5.65 per barrel lower than the last year's $70.70. Occidental's average realized price for the 2007 second quarter was $2.55 lower than in the comparable period last year. The differentials in the second quarter narrowed mainly in the Middle East and domestically at Elk Hills. The NYMEX gas price for the quarter was $7.56, compared to $7.26 for the second quarter of 2006. Oxy's domestic realized price for the quarter was $7.07, up from $6.23 for the second quarter of last year. Worldwide oil and gas production for the quarter averaged 583,000 barrels of oil equivalent per day, compared to 609,000 in the second quarter of last year. The second quarter production excluding volumes from the Russian non-operated asset sale in January, the Horn Mountain swap and the Pakistan sale in June was 558,000 in the second quarter 2007, compared to 551,000 in the same basis for the last year. Our guidance for the second quarter was in the range of 585,000 to 600,000 barrels a day. We were slightly under this range due to the impact of product prices that reduced our volumes for production sharing contracts in the Middle East by approximately 3,000 barrels a day. In this product price range for the current quarter, each dollar per barrel change in the price of oil impacts production by 600 barrels a day. We also had some weather related downtime in the Permian and processing plant maintenance in Libya during the quarter. Exploration expense of $93 million in the quarter was lower than our previous guidance of $110 million. The second quarter of 2007 expense was $43 million higher than the second quarter of last year, the increase coming from the Middle East and North Africa. Oil and gas production costs for the first half of 2007 were $12.30 a barrel compared to last year's $11.70. The increases were a result of higher field operating and maintenance expenses. Chemical segment earnings for the second quarter of 2007 of $158 million was in line with our first quarter conference call guidance. Chemicals earned $251 million in last year's second quarter. The primary factor that accounted for the quarter-to-quarter difference was lower chloro-vinyl margins due to lower demand. Net interest expense, excluding debt retirement charges, was a net $1 million during the second quarter of 2007, compared to $33 million expense last year. The worldwide effective tax rate, excluding the impact of asset sales and other significant items, was 46% for the second quarter of 2007, 3 percentage points lower than our guidance. The lower rate reflects a change in the mix with more income coming from U.S. sources and higher taxed foreign sources, especially the lower exploration expenses outside the United States. Now, let me briefly turn to Oxy's performance during the first 6 months. Net income was $2.624 billion or $3.11 per diluted share for the first 6 months, compared with $2.091 billion or $242 per diluted share for the same period last year. In addition to the asset sales recorded in the second quarter, the 6 months of 2007 also includes income of $387 million net of tax for the following: $412 million gain from the sale of our Russian investment, $112 million gain form litigation settlements, $107 million charge for cash tender offers for various debt issues and a $30 million provision for a plant closure. Worldwide oil and gas production for six months averaged 587,000 barrels a day, compared to 601,000 for the six months of last year after excluding Russia, Pakistan and Horn Mountain 559,000 barrels for first six months of 2007 was a 3% increase over the 542,000 barrel a days for the same period last year. Capital spending was $850 million for the quarter and $1.63 billion for the first six months. We expect total capital spending for the year to be in the range of $3.4 billion to $3.5 billion. Cash flow from operations for the six months was approximately $2.9 billion. We have received total proceeds of $485 million from sale of our interest in the Russian joint venture, $55 million from the sale of domestic mineral ventures and $600 million from the sale of our 19 million shares of Lyondell. We used $1.6 billion of the company's cash flow to fund capital expenditures, $500 million for acquisitions, $1.1 billion to repurchase debt and $370 million to pay dividends. In addition, we spent $550 million to repurchase $11.2 million common shares at an average price of $49.84 per share. These net outlays reduced our $1.6 billion cash balance at the end of last year by $100 million to $1.5 billion at June 30. Debt was $2 billion at the end of June, with non-current debt of $1.7 billion. The weighted average basic shares outstanding for the six months were $839.3 million and the weighted average diluted shares outstanding were $843.2 million. At June 30, there were $835.1 million basic shares outstanding and the fully diluted share amount was approximately $839 million. Our debt to capitalization ratio was 9% down from 13% at the end of last year. Over the first half of the year, Occidentals' annual return on equity was 26% and our annualized return on capital employed was 24%. As we look ahead in the current quarter, we expect oil and gas production to be in the range of 585,000 to 590,000 BOE a day during the quarter. The increase includes 17,000 BOE a day from Dolphin, 7,000 BOE a day from the Permian assets acquired in the BP swap and 4,000 BOE a day for the announced acquisition of Qatar assets from Anadarko. These increases will be partially offset by the sale of Pakistan and the swap of Horn Mountain which reduced third quarter production by 25,000 barrels a day compared to the second quarter. Dolphin is expected to contribute $10 million to pre-tax income, during the third quarter start up. Third quarter income reflects lower start up gas sales and pipeline tariff volumes. We're not anticipating liftings of NGLs initial inventories build up. Additionally, the third quarter will have start up expenses and full operating costs including interest on the pipeline operations, which is capitalized during construction. Income will increase sharply as production ramps up to capacity. We expect oil and gas production year-end exit rate to be in the range of 630,000 to 650,000 barrels a day. This increase includes 47,000 to 65,000 BOE a day from Dolphin, 7,000 BOE from the Permian assets acquired in the BP swap and 6,000 BOE a day from the announced acquisition of Qatar assets from Anadarko. With regard to prices of dollar per barrel change in oil prices impacts oil and gas quarterly earnings by about $40 million before income taxes. A swing of $0.50 per million BTU in gas prices has a $24 million impact on quarterly earnings before income taxes. The NYMEX gas prices for the second quarter was $7.56 per thousand cubic feet. Additionally, we expect exploration expense to be about $95 million for seismic and drilling for our Libyan, South American exploration programs. We expect chemical segment our earnings to be in the range of $160 million to $175 million, compared to $158 million in the second quarter. We expect interest expense to be about $12 million in the third quarter. The increase in the second quarter reflects the loss of capitalized interest in the Dolphin Project. We expect our combined worldwide tax rate in the third quarter increased about 47% due to increases in foreign exploration. Our second quarter and six month U.S. and foreign tax rates are included in the Investor Relations Supplemental Schedule.
