Geophysical Exploration Methods for Subsurface Imaging

Geophysical methods are eye of geothermal exploration. They allow geosciences to image subsurface structures, infer rock properties, and identify zone of high heat flow andd fluid satiation with out examinately resorting to loadsive drilling. Each geophysical technique measures a different physical exacy of thee subsurface, and integrating multiple methods providesides a more robuss interpretation than any single technique alone.

Seismic Surveys

Seismic reflection and refraction gestions are among te mect powerful tools for mapping subsurface structure.

Geological Criteria for Site Selection

While geophysical methods provide thee subsurface images, geological assessments provide thee context and interpretation.

A thorough geological evaluation is essential for translating geophysical anomalies into viable drilliling contens.
