Abstract

fetched live from OpenAlex

Broadly defined, seismic attribute studies (“attribute studies”) are attempts to use attributes derived from seismic data to predict the distribution of physical properties (e.g., porosity, lithology, bed thickness) of the strata being imaged seismically. Attribute studies may be either quantitative (i.e., the objective is to make numerical predictions of properties of interest throughout the seismic coverage) or qualitative (i.e., the objective is to find geobodies sharing similar physical properties). In either case, the interpreter must decide which attributes to derive, how to analyze the attributes, and (not least importantly) how to test the results of the correlation exercise before making exploration or development decisions.

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.
