Vapor-Dominated Geothermal Resources: (2) Reservoir Engineering Characteristics and Related Tasks for Further Studies

Abstract

Vapor-dominated geothermal resources were the first to be utilized for geothermal power generation. However, since there are few examples, its characteristics, actual conditions and issues are not well known to the general public. This review intends to provide an overview of the current understanding of the vapordominated geothermal resources, the phenomena that have occurred during steam production, the responses to these phenomena, and the issues that remain unresolved. This review is divided into three parts. In the second part, we will review reservoir engineering characteristics of vapor-dominated geothermal resources, various analysis methods, and related tasks for further studies.
