It forces the interpreter to prove that an interpretation is possible, and it eliminates impossible models even seismic models. A simple depth estimate may be all the model one needs to eliminate an idea. Other times, we need a careful and detailed model to help us understand what’s possible and unambiguously impossible.</span></p> application/pdf en Society of Exploration Geophysicists General philosophy 5: Concerning nonuniqueness chapter
