Evaluation of hydrocarbon accumulation conditions for shale gas from the Eastern Sag of the Liaohe Oilfield and its gas-bearing properties
Bibliographic record
Abstract
In comparison with the organic matter type,organic carbon abundance,thermal maturity and thickness of source rocks in shale-gas-bearing basins abroad,the present paper preliminarily confirmed the conditions for shale-gas accumulation in the Eastern Sag of the Liaohe Oilfield.The experimental study on gas amounts absorbed by shales indicated that there existed a positive correlation between the absorbed gas amount and the TOC and thermal maturity of dark mud shales in the Eastern Sag,and its adsorbed gas amount was 0.2～1.2 m3/t,basically equal to that of the Gordondale shale in Canada and the Lower Silurian Longmaxi Formation shale of the Sichuan Basin.A comprehensive evaluation on gas-bearing properties of shales in various formations was made by using abnormal values from the total hydrocarbon by gas logging and being combined with other criteria,such as TOC,Ro,thickness of the corresponding shales,therefore,the most favorable block for shale-gas exploration within the Eastern Sag was targeted for the Erjiegou-Jiazhangsi area.

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.
