ABSTRACT

Advances in virtual outcrop technologies and their introduction to Previous HitfractureNext Hit characterization allow extraction of Previous HitfractureNext Hit data from very large and inaccessible areas. The recent development of automated or semiautomated methods for Previous HitfractureNext Hit extraction aims to reduce or avoid tedious, time-consuming, and biased manual interpretation of fractures from virtual outcrops. We present a benchmarking exercise between a previously proposed automated Previous HitfractureNext Hit picking method, manual picking, and fieldwork methods. Comparison between the three methods highlighted their relative advantages and limitations. The automated Previous HitfractureNext Hit picking method provided excellent results in terms of Previous HitfractureNext Hit orientation, size, spatial distribution, and density. Fieldwork is complementary to Previous HitfractureNext Hit extraction from virtual outcrops, and it should focus on quality control of remote sensing data, poorly exposed areas, small-scale observations, diagenesis, timing of Previous HitfractureNext Hit development, building conceptual models, and linking Previous HitfractureNext Hit stratigraphy to rock properties. We propose a best practice for the use and integration of manual and/or automated Previous HitfractureNext Hit extraction from virtual outcrop and fieldwork data for Previous HitfractureTop characterization and modeling from outcrop analogs. We consider integration of different methods as the best way to improve the modeling exercise while reducing operational costs and risks.
