Smoky Hill Project

In the Smoky Hill project area, drilling of the Steamboat Hansen 8-10 well in October of 2012 discovered what has become the Arikaree Creek oilfield. This discovery is in the Mississippian age Spergen formation, the first discovery of this type in this area of Colorado. A petrologic evaluation commissioned by Nighthawk  confirmed the existence of enhanced secondary porosity through hydrothermal alteration of the original reservoir. Nighthawk believes that this enhanced reservoir may be a contributing factor for the strong production performance of the wells in the Arikaree Creek field.

The Big Sky 4-11 well encountered 32 feet of gross pay interval at 8,030 feet in the target formation of the Mississippian Spergen. The Big Sky well was drilled on the same structure as the Steamboat Hansen 8-10 discovery well, drilled in October 2012, and has confirmed a significant north-east extension of Nighthawk’s Arikaree Creek oilfield. The pay interval encountered by the Big Sky 4-11 well is similar in size and characteristics to the productive interval in the Steamboat Hansen 8-10 well. Logs from the Big Sky 4-11 well have also confirmed a number of stacked pay opportunities up-hole from the Mississippian.

The Taos 1-10 well spudded on 17 May 2013 is located on the Arikaree Creek structure midway between the Big Sky 4-11 and Steamboat Hansen 8-10 wells. Taos 1-10 targeted the same formation as the Big Sky 4-11; the Mississippian Spergen formation.  The Taos 1-10 well commenced production on June 14, 2013 with initial production rates of 400-500 bopd.  As of July 2017, there are 11 producing wells in the Arikaree Creek field.

Total production from the Arikaree Creek oilfield has exceeded 2 million bbls of oil  as of July 2017.
