What does KRU stand for?

Alpine is located 35 miles west of the Kuparuk River Unit on the border of the National Petroleum Reserve-Alaska.

Pioneer has been negotiating with current North Slope producers in the Kuparuk River unit on a facility-sharing agreement for Oooguruk's production.

The rig set several drilling records while working for ARCO in the Kuparuk River Unit on the North Slope of Alaska.

Tarn is a 50 million barrel oil accumulation and the second satellite accumulation to begin production in the Kuparuk River Unit since December 1997.

Pioneer is the operator of the field, which is in the shallow waters of the Beaufort Sea approximately eight miles northwest of the Kuparuk River Unit.

Some natural gas liquids are produced and blended with oil shipped down the trans-Alaska oil pipeline, while other NGLs are shipped from Prudhoe Bay to the Kuparuk River Unit for use in the Large-Scale Enhance Oil Recovery project.

The agreement provides for joint exploration and appraisal of a 580- square-mile area that includes the ARCO-operated Kuparuk River Unit and adjacent acreage.

4 million acres in an under-explored area with various leads and prospects -- Storms Lead Area (50% working interest and operator) 130,000-acre position adjacent to the giant Prudhoe Bay and Kuparuk River Units -- Tuvaaq Offshore Lease (40% working interest) A 14,000-acre block northeast of Pioneer's Oooguruk Unit with a primary objective in the Ivishak sands and a secondary objective in the Schrader Bluff sands encountered in the adjacent Nikaitchuq Unit Drilling operations have concluded on the Tuvaaq exploration well.
