This week's U.S. air strikes in northern Iraq are being accompanied with an undertow of it's all about oil" talk. Take for example, Columbia School of Journalism Dean Steve Coll's observation in The New Yorker, that "Obama's defense of Erbil (capital of the semiautonomous Kurdish region) is effectively the defense of an undeclared Kurdish oil state." It's no secret that Iraqi Kurdistan has an abundance of oil reserves, nor that U.S. oil companies, like [Chevron] are busy exploring there. Chevron has three "production sharing contracts" with the Kurdish government, covering a combined 444,000 acres, north of Irbil, where it's in the early testing and drilling stage. And it likes what it sees. Asked for an update, a Chevron spokesman said Monday, "We continue monitoring the situation. We remain in regular contact with the Kurdistan Regional Government and are dedicated to supporting the (Kurdistan Region of Iraq) in developing its natural resources." A potentially bigger worry for both Chevron and the Kurds .. could be if Iraq did stabilize and unite, with Kurdistan under its umbrella. For Chevron ... a new arrangement in Iraq could entail the renegotiation of contracts it has with the Kurds, which by the way, Baghdad refused to recognize. Kurdistan's oil pipeline via Turkey continues to pump out oil - 120,000 barrels per day.
