Abstract

fetched live from OpenAlex

The search for methane hydrate accumulations has been conducted in the Northern regions of Siberia for more than 50 years. During this time, it failed reliably (with the rise of hydrate-containing core) taken from the borehole to discover any deposits of methane hydrates even in the rocks of the Western Siberian basin, which has been well studied by drilling. On the example of the discovery of two methane hydrates deposits in Canada and China, it is shown that to solve the problem it is necessary to conduct specially organized and technically secured drilling operations on the pre-selected promising areas. For the first time, the parameters of the methane hydrates stability zone in the sedimentary cover of the Vilyuysk syneclise were estimated.

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.
