How data helped answer the question of why testing results in a geothermal well disappointed.

The article discusses the unexpected importance of resistivity data in geothermal exploration, specifically in the Amstelland-01 well in the Netherlands. Topics include the challenges faced in mapping subsurface geothermal potential, the role of resistivity logs in assessing reservoir performance, and how the analysis of core data and resistivity logs helped explain lower-than-expected production rates.
