Workers adjust a valve of an oil pipe in Tawke oil field near Dahuk, 400 km (249 miles) north of Baghdad, November 24, 2010. In this part of Iraq, the hillsides sweat oil. Without any coaxing, the sticky black treasure oozes from the layered rock and gathers in pools that bubble as dissolved gases surface. Gradually, as the crude slips down the hillsides, it solidifies into a grey mass that resembles a hardened lava flow. It’s a good metaphor for the progress of oil from the semi-autonomous Iraqi region of Kurdistan over the past five years: big on promise, small on delivery. Picture taken November 24, 2010.
