ABSTRACT

This paper surveys the application of well log analysis principles in the exploration and exploitation of geothermal resources:

  • hot-water reservoirs,

  • steam reservoirs,

  • geopressured hot water reservoirs and

  • hot dry rock.

In the first section we present a brief summary of the salient features of these geothermal resources as they pertain to well log analysis. The second section covers the current practices and future requirements in geothermal well logging. The third section deals with the specific problems in the interpretation of geothermal well logs as compared to those from petroleum wells. Relevant examples are provided from the geothermal fields in the Imperial Valley, California; Raft River Idaho;and the Jemez Mountain area, New Mexico. The concluding section includes a discussion of the various proved and possible applications of well log analysis in the geothermal industry.
