Resource assessment and onshore production tests of methane hydrate
Bibliographic record
Abstract
Methane hydrate, often called “fiery ice”, has been examined as a possible future energy source. MH21 (the Research Consortium for Methane Hydrate Resources in Japan) has advanced methane hydrate exploitation study covering the resource assessment around the Japan arc and the development of methane hydrate production technology since 2002. The existence of more than 10 methane hydrate concentrated zones were delineated in the Eastern Nankai Trough area and it was calculated that methane hydrate resources (in-place) in those methane hydrate concentrated zones corresponded to 20 tcf of methane gas. To verify the production techniques, twice onshore production tests have been conducted in the Canadian Arctic under international collaborations. Following the first production test in 2002 in which the thermal stimulation technique lead to the world's first gas production from methane hydrate-bearing sediment, the second test was performed to realize the depressurization for in-situ methane hydrate dissociation in 2007 and 2008. The discovery of the methane hydrate concentrated zones and the applicability of the energy efficient depressurization technique are important milestones to bring methane hydrate from an exotic material to real resource.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
