Abstract
An approximate estimation of the heat flow value was performed for three deep parametric wells drilled in the northern part of the Indigiro-Zyryansky trough. Boreholes have uncovered Paleogene and Upper Jurassic rocks. Geothermal gradients were calculated from the temperature values at the lower boundary of the cryolithozone (0 ºC) and at the downhole. The thermal conductivity of rocks was roughly estimated from published data. The calculated heat flow on the Indigirskaya area is on average 70 mW/m2 . The values of heat flow values were recorded in the previously studied neighboring areas. Thus, the heat flow estimate obtained by the authors in the Indigiro-Zyryansky trough correspond fully to the available data on the heat flow level in this region of East Yakutia.
