Overview of thermal-stimulation production-test results for the JAPEX/JNOC/GSC et al. Mallik 5L-38 gas hydrate production research well
Bibliographic record
Abstract
The thermal-stimulation test conducted on the JAPEX/JNOC/GSC et al. Mallik 5L-38 gas hydrate production research well in March of 2002 was designed to increase the in situ temperature of a portion of a well defined and constrained gas hydrate reservoir above the gas hydrate stability point,while maintaining constant pressure. Data collected, including surface and downhole instrumentation readings and data from advanced logging and seismic programs, were then used to calibrate numerical gas hydrate reservoir simulation models and determine the kinetic and thermodynamic properties of the in situ gas hydrate. The thermal-stimulation test was successful: bottomhole temperature was increased to greater than 50°C during the test; gas from dissociated gas hydrate was produced, sampled, and flared at surface; and significant amounts of real-time downhole temperature and pressure data, as well as other scientific measurements, were obtained.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
