An organic geochemical investigation of the Carboniferous Mabou Group intersected by groundwater wells in McCully Gas Field, southern New Brunswick - its hydrocarbon source potential and character
Bibliographic record
Abstract
Water wells were drilled in November 2015 over the McCully gas field in southern New Brunswick as part of the Geological Survey of Canada (GSC) Environmental Geoscience program. Drill cuttings were collected and immediately put in Isojars at the well sites. Cuttings samples from PO-01 to PO-06 wells have been submitted to the Organic Geochemistry and Petrology Laboratories at the GSC-Calgary for Rock-Eval and hydrocarbon compositional analyses to evaluate their hydrocarbon potential, hydrocarbon property and source rock characteristics. Cuttings from one well (PO-06) have generated results indicative of presence of organic matter and hydrocarbons in the rock although no dissolved hydrocarbons were detected in groundwater at the well site. New Rock-Eval analyses were carried out on the cuttings as well as organic extracts and detailed geochemistry to further address the issue of either in situ hydrocarbon production or external hydrocarbon charge into the sediments.

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.
