(Kezhen) Determination of geothermal gradient from borehole temperature and permafrost base for exploration wells in the Beaufort-Mackenzie Basin [electronic resource] / [by] K. Hu, Z. Chen, and D.R. Issler. Ottawa : Natural Resources Canada, 2014. 286 p. : figures, graphs, tables. Open file (Geological Survey of Canada) ; 6957 Includes bibliographical references. This report documents geothermal gradient values and their quality assessment for 259 petroleum exploration wells that were used for constructing a geothermal gradient contour map for the Beaufort-Mackenzie Basin. First-order, linear geothermal gradients were determined by applying constrained least-squares fits to the deep temperature data obtained during well testing and logging with the requirement that they intersect the mapped base of permafrost at an assumed temperature of 0 ºC. Geothermal gradient values were quality-assessed based on the quality and quantity of the individual temperature points used for the calculations and the quality of the fit to the data as represented by the coefficient of determination. Calculated geothermal gradients vary from approximately 15 °C/km to 48 °C/km across the Beaufort-Mackenzie Basin, and a large fraction of the basin is characterized by typical sedimentary basin geothermal gradients of 25 °C/km to 35 °C/km (> 200 wells). gccst Surficial geology gccst Geomorphology gccst Permafrost Issler, Dale.
