Rock petrophysical analysis of Upper Devonian Jean Marie gas reservoir rocks in the July Lake area of northeastern British Columbia and in the contiguous area in northwestern Alberta
Bibliographic record
Abstract
This paper provides a summary of the rock petrophysical analysis of the Upper Devonian Jean Marie Member (Redknife Formation) from the July Lake area of northeastern British Columbia and the contiguous area of northwestern Alberta. The database includes 198 one-inch (2.54 cm) diameter core plugs sampled from 18 cores in the July Lake area and 18 one-inch (2.54 cm) diameter core plugs sampled from 5 cores in northwestern Alberta. Overall, the analysis includes data obtained (number of samples shown in parentheses) for porosity (215), grain density (215), routine air permeability (216), in situ Klinkenberg permeability (216), pore volume compressibility (26), the Archie cementation exponent electrical property (71), effective gas permeability at critical water saturation (40), relative gas permeability at critical water saturation (40), critical brine saturation (67) and mercury intrusion drainage capillary pressure analysis (40). Key rock petrophysical data is also summarized for the two most significant reservoir facies at July Lake, the platy stromatoporoid-Renalcis reef facies and the detrital stromatoporoid-coral foreslope facies.
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.

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.
