The Rockies cover Newfield’s assets in the Uinta Basin of Utah and the Williston Basin of North Dakota.
In the Uinta Basin, we have more than 215,000 net acres which represent about 16 percent of our total proved reserves at year-end 2015. We signed a wellbore development agreement in early 2016 with a third party partner to drill and complete up to 20 horizontal wells targeting the Uteland Butte and Wasatch formations in Utah's Uinta Basin. We will run one rig and manage the drilling, completion and production operations, with a portion of its working interests being carried on a promoted basis. Drilling is expected to be conducted in 2016 and 2017.
In the Williston Basin, we have approximately 85,000 net acres, representing about 10 percent of our total proved reserves at year-end 2015. In 2016, we will be running one rig.
