For six consecutive years, ChevronTexaco has had good news for anyone worried that the world is running out of oil: the company has found more oil and natural gas than it has produced. Over that time, ChevronTexaco’s proven oil and gas reserves have risen 14 percent, more than one billion barrels.
But near the bottom of ChevronTexaco’s financial filings is a much less promising statistic. For each of those years, ChevronTexaco’s wells have produced less oil and gas than the year before. Even as reserves have risen, the company’s annual output has fallen by almost 15 percent, and the declines have continued recently despite a company promise to increase production in 2002.
