DENVER--(BUSINESS WIRE)-- Whiting Petroleum Corporation is issuing an update on the well incident at the Roggenbuck 14-25H well in North Dakota disclosed in Whiting’s November 21, 2010 press release. As previously disclosed, a valve near the wellhead failed resulting in water, oil and natural gas flowing from the well, with Whiting containing and hauling from the well site the liquids being produced.

Whiting believes that flow of liquids from the well started declining early Sunday morning November 21, 2010. From Saturday afternoon through 6:00 a.m. (CST) Monday, November 22, 2010 approximately 5,630 barrels of water and 420 barrels of oil were hauled to a disposal facility from a lined pit on location where fluids are being collected. Whiting estimates that on Monday flow from the well had declined to approximately 25% of its initial flow rate. Early Monday the well was estimated to be flowing 50 – 70 barrels of fluid per hour: 90% water and 10% oil. All fluids continue to be collected and hauled to a disposal facility.

Personnel from Whiting, Whiting contractors and Wild Well Control, Inc. are progressing with operations to control the flow from the well.
