Progress in Laboratory Studies of Gas Hydrate in Porous Media at the Geological Survey of Canada
Bibliographic record
Abstract
Abstract In 1996 the Geological Survey of Canada (GSC), together with the Japan National Oil Corporation (JNOC) and the Japan Petroleum Exploration Company Ltd. (JAPEX) began planning and preparations for the 1998 drilling of the JAPEX/JNOC/GSC Mallik 2L-38 gas-hydrate research well at the Mallik site in Canada's Mackenzie delta, Northwest Territories. In the course of that program, and the subsequent Mallik 2002 gas hydrate production research well program, significant progress has been realized with respect to laboratory research into the properties and behavior of gas hydrate in both artificial and natural porous media. This included the establishment of a basic capability to successfully grow gas hydrate within the pore volume of natural sediments and/or synthetic quartz analogs, development of a dielectric technique for direct quantification of gas-hydrate amounts in laboratory test specimens, determination of the thermal conductivity of gas-hydrate-bearing sediments, and documentation of pressure-temperature-salinity influences on gas-hydrate stability in Mallik reservoir sediments. This work has contributed directly to the fundamental understanding of gas-hydrate occurrences in nature, to the specification of appropriate values for critical parameters used in gas-hydrate production models, and to the design and evaluation of practical production scenarios to be employed in an extended production test of a natural-gas-hydrate deposit anticipated in the near future.

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.
