Abstract

fetched live from OpenAlex

Abstract Earth models are routinely used in the oil and gas industry to integrate multidisciplinary data for subsurface property predictions. Even though most earth models predict reasonably well at the field scale, they often fail to accurately predict the subsurface conditions at a specific location, especially in geologically complex reservoirs. Earth models can become more predictive by integrating information routinely extracted from 3D seismic such as faults, stratigraphy, facies, and rock properties. But their integration into earth models is often done without accounting for their uncertainties, potentially leading to the misprediction of the subsurface properties. We aimed to review several seismic interpretation techniques that provided useful input to better constrain earth models and to suggest ways to account for the interpretation uncertainty in these models. We determined the pitfalls and practical solutions for a successful quantitative seismic interpretation that can lead to more predictive earth models.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
