Temperature measurements at the surface and in shallow boreholes

Abstract

In its first part, the present work compares the results of two different but complementary approaches in geothermal investigations i.e. structural geology and geothermal mapping. A con- formity and a close correspondence are underlined by the shallow temperature measurements carried out at Reykholt-Reykjavellir area, South-Iceland. Temperature logging and interpretation are the subjects of the second part of this report. Five wells were logged and the temperature gradients calculated from the logs are similar to the regional gradient.
