PARAMETER PRIORITY ANALYSIS TO EVALUATE THE PROSPECT OF GEOTHERMAL OBJECTS UTILIZATION
In the article analyses of parameter priority to evaluate the prospect of the geothermal objects utilization to determine the possibility and prospects of their use for the purpose of energy supply has been executed by the method of expert estimation. The geothermal object is nominal well on the basis of which possible to establishment of the geothermal energy distribution system bearing in mind the potential consumer. For expert estimation a survey questionnaire worked out and a representative group of experts was composed in the amount of 12 people. The average expert competency coefficient was 8 points on a ten-point scale. The parameters of two categories are considered. The first parameters are related to the availability of geothermal resource, the second - to the conditions of transportation and features of potential energy consumers. In total, 30 parameters were analyzed in the survey. Weighting coefficients were set for each parameter. The survey results were processed by finding arithmetic, weighted average and median scores. The degree of experts' opinions agreement on each parameter was determined by the method of finding the coefficient of variation. For the whole expert poll in general was determined by the coefficient of Kendell's concordance. The calculations showed that the consistency of expert estimates is sufficient to decide on a list of priority parameters and their weighting factors. . The obtained results can be used in the creation of the geothermal databases and in the development of a methodology for selecting prospective wells for the primary development of geothermal resources.
