Gas production wasboosted by increased volumes through Shell’s Obaiyed processing plant; higheroil output reflected higher condensate production from the gas flow throughObaiyed and several new wells.The Egypt Region’s drilling program yielded several new oil and gas fielddiscoveries in the Western Desert. Start-up procedures are under way at thetwo new processing trains at Salam Base on the Khalda Concession. “We expectto reach our targeted net production of 100 million cubic feet (MMcf) of gasand 5,000 barrels of condensate per day from the two plants during the secondquarter,” Farris said.In Australia, gas production increased 21 percent as repairs at Varanus Islandneared completion.

From time to time, Apache posts announcements,updates and investor information, in addition to copies of all press releases,on its Web site, ceiling testApache uses the full-cost method of accounting. The company is required toperform a calculation that establishes a ceiling on the carrying costs of itsoil and gas properties in each country at the end of each quarter. The ceilingis the calculated present value of estimated future net cash flows from provedoil and gas reserves, using a 10-percent discount rate, plus the lower of thecost or fair value of unproved properties, net of related tax effects. Therules generally require pricing future production at oil and gas prices ineffect at the end of the quarter.

If the ceiling is exceeded, a non-cashwrite-down is required. The calculation does not allow for consideration ofpossible or probable reserves or expected future trends in commodity prices ordrilling and service costs. *Adjusted earnings and cash from operations before changes in operating assetsand liabilities are non-GAAP measures.
