Surveys for a large number of wells across the North Slope. This data is sparse for the NANA region, as there are only two deep wells with available data. Both of these wells were drilled in the Kotzebue Basin and were evaluated in the 1981 study of the Kotzebue district heating system (ESI, 1981). These are: 1) The 8,373-foot deep Cape Espenberg well; and 2) The 6,311-foot deep Nimiuk Point well. The geothermal gradient calculated for the Cape Espenburg well was more or less normal (approximately 30 °C / 100 m), but the gradient calculated for the Nimiuk Point well was slightly above average (40-45 °C / 100 m). Unfortunately, two data points are not sufficient to define any sort of regional trends. To remedy this problem, additional well data – for shallow wells – was requested from the Alaska Well “headers” from AK Oil&Gas Conservation commission (see Table 1). As of the writing of this report that data has not yet arrived. Well logs should be obtained for any additional wells in the NANA region as part of the site visits.

Wells in the prospective NANA Region. Six aeromagnetic maps were obtained from the USGS Alaska Digital Aeromagnetic Database that cover the NANA region. Details on the aeromagnetic data can be found at http://pubs.usgs.gov/of/1999/ofr-99-0503/. Aeromagnetic maps show the spatial distribution and relative abundance of magnetic minerals (iron oxides) in the upper levels of the crust. Because different rock types differ in their content of magnetic minerals, the magnetic map allows a visualization of the geologic structure of the upper subsurface (www.wikipedia.org). For example, the iron mineral magnetite is abundant in volcanic and some plutonic rocks, distinguishing them from sedimentary rocks that tend to have low to zero iron content. It is important to note that aeromagnetic maps cannot be used to “see” geothermal resources; but they can aid in geologic interpretations and thus aid in predicting the occurrences of subsurface thermal reservoirs. An example of an aeromagnetic map is shown in Fig. 5. This map, considered in the context of other geologic and geophysical data, can be utilized to target certain locations that satisfy the seemingly requisite conditions for geothermal resources in the NANA region. Based on what we know about almost all hot springs in the CAHSB, geothermal resources are likely to occur at the pluton margins; or if it is a composite pluton, at the contact between different plutonic phases (see Sainsbury and others, 1980; and Kolker and others, 2007). Fig. 5 shows the location of one possible intersection between fault(s) and a pluton (indicated by a white star). In the case of known hot springs, careful examination of aeromagnetic maps can also aid in understanding subsurface structures and therefore speculating on the geometry of the feeder hydrothermal reservoir. 10PDF Image | NANA Geothermal Assessment Project (GAP) Results
