Positioning the fluid collector on the ground of borehole geothermal analysis

In the area of the Republic of Croatia there exist some 4.000 deep boreholes. Using the geological and geophysical data as well as the rock samples from these boreholes certain geothermal analyses can be acomplished. On the ground of these analyses one can reason about the collector properties of the pierced sedimentary rocks, as well as the sediments in the close vicinity of the borehole channel. This paper presents the model of the relationship between the heat-flow density by conduction, and the collector position. Also, the results of geothermal analyses of the boreholes KBNZ-1A and Šalata-1 are presented. On the account of the model and effected analyses the conclusions are drawn about the perspectives of the future research activities on the same locations. The results of the accomplished investigations indicate that the results of the geothermal analyses can be helpful in making decisions about further research activities in a defined area.
