Geothermal Well Test Analysis: Fundamentals, Applications and Advanced Techniques

An introduction to the different types of geothermal systems both conventional and non-conventional (EGS) is given, with reference to the relevant well design. The book provides a comprehensive review of geothermal pressure transient analysis methodology, and the similarities and differences with petroleum and ground water well test analysis. Also discussed are the different tests undertaken in geothermal wells during completion testing, output/production testing and the interpretation of the data. Attention is given to the practical aspects of undertaking testing in geothermal wells, some of the common problems encountered and possible solutions. The major content and most novel part of the book focuses on pressure transient analysis by numerical simulation and inverse methods, coupled with the use of the familiar pressure derivative plot. Non-standard geothermal pressure transient behaviors are analysed and interpreted by numerical techniques for cases beyond the limit of existing analytical techniques. Throughout the book, well testing concepts are illustrated with field data from real geothermal wells. A guide to analysis of well test data in geothermal wells, including pressure transient analysis, completion testing and output testing. Provides practical information on how to avoid common issues with data collection in geothermal wells. Uses SI units, converting existing equations and models found in literature to this unit system, instead of oilfield units. INDICE: 1. Introduction 2. Geothermal Systems and Types of Wells 3.
