Repsol SA pulled all foreign workers from its oil fields in Venezuela amid a deepening political crisis, while Chevron Corp. and Total SA have removed a small number of employees, said people with knowledge of the companies. Norway’s Statoil ASA has withdrawn its expatriate staff. Repsol field workers left the country in the past few weeks, two people said, asking not to be identified discussing a confidential matter. A skeleton staff remains in Caracas, one of the people said. Chevron has removed fewer than 10 foreign employees and retains a substantial expatriate workforce there, said people with knowledge who weren’t authorized to discuss the operations. Statoil withdrew its last three foreign workers before the July 30 election, Erik Haaland, a company spokesman said. The departure of workers will be a concern to the government because oil output, which has tumbled over the past two years, accounts for 95 percent of Venezuela’s foreign-currency earnings. Repsol gets about 10 percent of its production from the country, where it owns a stake in the Carabobo heavy-oil field. The Spanish company also is a partner in the Perla project, Latin America’s largest offshore gas deposit, together with Eni SpA.
