Nigerian Strike Shuts Second Chevron Field: A Chevron Corp. representative would not identify the field, which is in the Escravos region of Nigeria, or give production figures. Chevron’s operations in Nigeria “are continuing, but we are obviously impacted by the strike activity,” spokeswoman Jan Golon said. Some 60,000 oil and gas workers from two unions are on strike, demanding that the military regime pay off $500 million owed to joint-venture partners and release jailed leaders, among them Mashood Abiola, who is believed to have won the presidency last year before the military annulled the elections.
