    Prospecting and Producing of Geothermal Energy | RILS

    This is a Remote Instructor Led Series (RILS) training. The remote classroom delivery is a modality that takes advantage of the instructor led training content, while allowing the same content to be delivered remotely.

    All training sessions will be delivered online with no face-to-face classroom attendance. This class will be delivered in 20h (4 hours daily teaching sessions over 5 days)

    This course focuses on geothermal methods for analyzing conventional and unconventional geothermal systems, and developing geothermal reservoirs. The course is designed for exploration, production, and development geoscientists.

    Lectures show how geothermal analysis can reduce the risk associated with geothermal prospects, how to predict quality from inexpensive wellbore measurements, and how to identify reservoir heat transfer in conductively and advectively dominated reservoirs.  It provides interpretive guidelines for reservoir thermal signatures of various transient and steady-state heat transfer processes and teaches how to distinguish the overprint of steady-state conductive geotherms by various steady-state and transient processes. Participants learn how to derive thermophysical rock properties from geophysical conventional logs, and how field and lab techniques can be combined to estimate geothermal prospects.

    Case studies illustrate and assess different types of geothermal resources, the design and layout of geothermal heat production schemes for direct use and for conversion into electric energy.  The lectures and discussions are designed to improve basic understanding of the processes controlling geothermal systems and terrestrial heat transport. This will enable interpreting various thermal signatures and evaluating geothermal potentials. 

    In contrast to the classroom version of this course, this remote course does not comprise exercise sessions.
