A Gulf hurricane now points at Chevron's rigs and its biggest refinery

Chevron (CVX) is pulling nonessential workers off its Gulf of Mexico platforms as Isaias, forecast to hit as a Category 2 hurricane late this week, bears down on the coast. Its Pascagoula plant in Mississippi, one of the largest US refineries, sits near the track. The same oil-supply strain that lifted Chevron's profits now threatens the facilities that earn them.
