DALLAS -- At the Oooguruk project on the North Slope of Alaska, operations are under way to drill four horizontal laterals in the Nuiqsut formation, according to Pioneer Natural Resources. Two of these laterals will be fracture-stimulated producing wells and two will be water injection wells.
The first water injection well has been completed and is being produced temporarily to measure the unstimulated productive capability of the Nuiqsut formation. It tested at an initial rate of 2,500 b/d of oil and has been put on production at a stabilized rate of approximately 1,000 b/d of oil, the company reports.
Later this year, the company will reevaluate its production profile to incorporate higher than expected performance from the Kuparuk wells, early waterflood results, and the performance of planned fracture-stimulated Nuiqsut wells, the company says.
Pioneer operates the Oooguruk project with a 70% working interest, and Eni Petroleum US holds a 30% working interest.
“The initial results from this Nuiqsut well are very encouraging, with initial production exceeding our expectations,” says Scott Sheffield, Pioneer’s chairman and CEO. “Pioneer’s net production from Oooguruk was forecast to average 5,000 b/d of oil in 2009 and gradually increase to 10,000 to 14,000 b/d of oil in 2011 as development drilling continues.”
