The Hot Ice well was drilled during the 2002-2003 and 2003-2004 winter drilling seasons, at a location approximately 20 miles south of the Kuparuk River Oil Field Center and about 40 miles southwest of Prudhoe Bay, Alaska. The well was drilled as part of a 2-year, cost-shared partnership between NETL, Anadarko Petroleum Corp., Maurer Technology Inc., and Noble Engineering and Development. It was drilled to test an Upper West Sak potential hydrate accumulation, based on updip hydrate shows in nearby Cirque and Tarn wells.
The Hot Ice well was drilled to a total measured depth of 2300 feet. The base of permafrost was encountered at 1263 feet, and the Upper West Sak target interval was encountered from 1463-1540 feet, just one foot higher than anticipated. Although the Upper West Sak sands lie within the theoretical Hydrate Stability Zone, and they have very good reservoir quality, they did not contain any hydrate. Instead of hydrate, the project team encountered free gas and water in the target interval.
The project successfully developed and demonstrated for the first time a number of innovative technologies, including Anadarko’s Arctic Drilling Platform, a mobile hydrate core analysis laboratory, and a new application of a continuous coring rig. The research team also acquired a 3D Vertical Seismic Profile at the well, which resulted in very high resolution images of the subsurface, and possible indications of hydrate updip and east of the well site. Analyses of the core, log, and seismic data from the well indicate that the hydrate in this region occurs in patchy deposits and may require a high methane flux from the subsurface in order to form more continuous drilling prospects.
The information obtained from the Hot Ice well will be used to improve maps of the lateral extent of the hydrate occurrences in Alaska, which will in turn improve resource estimates for the hydrate resource in Alaska. The technology developed to drill, log, core, and image the hydrate reservoir will be used to develop these resources in the future.
Also, this project puts into practice for the first time, Anadarko's Arctic Drilling Platform, which is a zero-footprint approach to drilling that is perfect for environmentally sensitive locations like the North Slope of Alaska. Furthermore, this project brings us closer to developing hydrates as an energy resource. Bringing hydrates into the energy mix would lead to a tremendous increase in the nation’s domestic natural gas resource, which would have a favorable impact on the U.S. economy.

Hot Ice No. 1 well location with Arctic Platform
(courtesy Anadarko Petroleum Corp.)
The drilling of the Hot Ice No. 1 well marked the first test of Anadarko's Arctic Platform. The primary platform consists of 16 lightweight aluminum modules fitted together and mounted on steel legs 12 ft (3.7 m) above the ground surface. The platform is large enough to contain a coring rig, auxiliary equipment, mud tanks, and the mobile core analysis laboratory. Another 5 modules form an adjacent platform with living quarters for 40 people. The Arctic Platform design permits light and air to reach the tundra grass that is visible at a drill site during the summer months and the relatively small and shallow holes created by the legs can be filled when drilling is completed. This system eliminates the need for ice pads or gravel pads that have a more destructive impact on the tundra landscape, while extending the time during which drilling can take place. The system components are delivered to the well site by Rolligon all-terrain vehicles with tundra-safe tires. The platform modules are also light enough for transport via helicopter.

Hot Ice No. 1 was cored with a wireline retrievable coring system using drilling mud that had been chilled to 23 °F (-5 °C) to preserve the 3.3-inch diameter (8.5 cm) core during the core's recovery. The mobile core laboratory was employed to immediately perform measurements on both the whole core and on one-inch plugs taken from the whole core, while maintaining that temperature. Whole core measurements included: core gamma log, infrared temperature, velocity measurement, geologic description and white light photographs, high resolution CT scan (equipment from LBNL), and a nuclear magnetic resonance measurement (CMR tool from Schlumberger) on a portion of each section of core. Plug measurements included: bulk volume, grain density, helium porosity and permeability at confining stress, P and S wave velocity, resistivity, and thermal conductivity. A Schlumberger CMR Tool was utilized to determine the fluid volume in the samples.
All engineering and scientific results are included in the project’s Final Report.
