USING GIS TO IMPROVE THERMAL CONDUCTIVITY ESTIMATES
Thermal conductivities of limestone core samples from the Madison formation in the Williston Basin were measured using the divided bar method and mapped in ArcGIS. Measured values ranged from 1.6 to 3.3 W/mK. A trend of increasing thermal conductivity values towards the center of the basin can be seen, and estimated conductivity values were obtained for the whole study area. Comparing the estimated values from the interpolation to actual measured values shows the accuracy of the estimates is significant enough for use in geologic modeling.
