A commemorative sign is seen at the location of the world's first ever prospective oil drilling site, built in 1813, in a forest near Merkwiller-Pechelbronn, May 7, 2014. Alsace, the cradle of the French oil exploration industry in the mid-18th century, is witnessing a tentative return of small oil explorers in the eastern region on the German border. With oil prices hovering around $100, a dozen fields are pumping again, in a region that once provided 5 percent of French needs and gave birth to international oil services giants such as Schlumberger, before fading into insignificance in the 1960s when the barrel lingered around $15.
