(Bloomberg) -- Pierre Henry farms wheat and corn east of Paris in an area famous for its Brie cheese. The next big hit might be crude oil. Henry’s farm, 78 kilometers from the French capital, sits atop what geologists call the Paris Basin, an area bordering Champagne and Chablis vineyards that struck oil in 1958. Henry leased a field to Exxon Mobil Corp. in 1985, which drilled wells that have pumped for a quarter century.
