Geothermal Well Test Analysis (eBook)

Geothermal Well Test Analysis: Fundamentals, Applications and Advanced Techniques provides a comprehensive review of the geothermal pressure transient analysis methodology and its similarities and differences with petroleum and groundwater well test analysis. Also discussed are the different tests undertaken in geothermal wells during completion testing, output/production testing, and the interpretation of data. In addition, the book focuses on pressure transient analysis by numerical simulation and inverse methods, also covering the familiar pressure derivative plot. Finally, non-standard geothermal pressure transient behaviors are analyzed and interpreted by numerical techniques for cases beyond the limit of existing analytical techniques.

• Provides a guide on the analysis of well test data in geothermal wells, including pressure transient analysis, completion testing and output testing
• Presents 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

Dr. Sadiq J. Zarrouk is a Senior Lecturer of Geothermal Engineering. He is the course coordinator for the Postgraduate Certificate in Geothermal Energy Technology programme at the Department of Engineering Science, The University of Auckland, New Zealand. Sadiq is also involved in professional geothermal energy training and research. In 2007, he was instrumental in the restart of the geothermal training programme at the University of Auckland. Dr. Zarrouk has an applied approach to geothermal research with on-going collaboration with several universities and research institutions worldwide. He has more than 120 publications in journals and conference proceedings and one book. Dr. Zarrouk has also been a member of the organising committee of the New Zealand Geothermal Workshop since 2006. He has passion for geothermal energy with an extensive 20 years commercial field experience in geothermal and reservoir engineering. He has worked on more than 35 geothermal fields in New Zealand, Australia, Indonesia, Malaysia, Philippines and North America. His roles involved the assessment of the resource, well targeting, well test analysis and reservoir modelling. He also participated in several due diligence projects, his role also included all the engineering aspects of the field development (steam field equipment, flow measurements, two-phase flow, power stations design, scaling, corrosion and direct use). Dr. Zarrouk has also provided expert evidence on several occasions. He was elected into the boards of directors of the New Zealand Geothermal Association in 2011 and the International Geothermal Association (IGA) in 2013, and continues to be an active board member of both organisations.
