Abstract
Geologic models are based on the interpretation of spatially sparse and limited resolution data sets. Nonunique interpretations often exist, resulting in commercial, safety, and environmental risks. We surveyed 444 experienced geoscientists to assess the validity of their interpretations of a seismic section for which multiple concepts honor the data. The most statistically influential factor in improving interpretation was writing about geologic time. A randomized controlled trial identified for the first time a significant causal link between being explicitly requested to describe the temporal geologic evolution of an interpretation and increased interpretation quality. These results have important implications for interpreting geologic data and communicating uncertainty in models.
Highlights
Geology is an interpretation-based science (Frodeman, 1995)
We recommend that companies would benefit from conducting controlled trials, using more complex in-house 2D and 3D data sets, with mixed teams of geologists and seismic interpreters: This approach would allow for optimization of industry work flows and would enable identification of best practice within a specific commercial environment
But using real seismic data for which there is no correct interpretation, we show that explicit consideration of temporal structural evolution of a section is rare among geoscientists, but it is the most influential factor in improving interpretation quality
Summary
Geology is an interpretation-based science (Frodeman, 1995). Waste disposal, carbon capture and storage, and hydrocarbon exploitation require an increasingly nuanced understanding of the subsurface. The REs had a median of 24.5 years of experience since completion of their highest degree, came from different technical backgrounds and they were acknowledged leading experts in seismic interpretation, structural geology, sedimentology, and tectonics.
