Abstract: The thermal conductivity on cores is measured in two steps (see Pribnow 1994). First, one face end of the core is sawed and polished. The half space line source is pressed against this preparated face (without further contact medium like water) by a computerized device. The position of the heat source is varied in 15 degree intervals around one semicircle. At each position, 3 repeating measurements are performed. The line source azimuth of the lowest measured thermal conductivity is the strike of the foliation plane. On the other hand, the thermal conductivity is maximal parallel to that direction. This apparent paradox can be explained by the experimental method, because the measurement plane is perpendicular to the orientation of the line source (Pribnow 1994).In a second step a calotte plane perpendicular to the strike of foliation is prepared. A second series of thermal conductivity measurements in 15 degree intervals ...

Abstract: In the KTB field laboratory, thermal conductivity was measured on cuttings material in depth intervals of 10 m and on available drill core material. The results on drill cores give anisotropy information. In general, the maximum thermal conductivity is measured parallel to the strike of foliation and the minimum thermal conductivity perpendicular to that direction. Approximately 250 g of cuttings of the fraction < 2 mm grain are mixed with water. This mixture of cuttings and water is measured (for more details see Pribnow et al. 1992 or Pribnow 1994). This measurement yields the geometric mean of the thermal conductivities in a two-phase mixture model. By measuring the weights of the dry cuttings and the mixture of cuttings and water, PHI is determined knowing the density of the cuttings and water (PHI = 32 %). Usually, the arithmetic mean value from 7 repeating measurements is used.
