Abstract

fetched live from OpenAlex

The miscible CO2 flood in Weyburn Field is a massive process for enhanced tertiary oil recovery and greenhouse gas sequestration, the largest of this kind ever in western Canada. This field, a mature Paleozoic carbonate pool of 1.4 billion-barrel reserves, has had nearly 48 years of conventional production history, mostly through waterflooding. Since October 2000 and in an effort to arrest production decline and improve recovery, the field operator has pipelined 50∼95 MMcf of CO2 each day as by-products of a coal gasification operation in North Dakota, and pumped it into the 30-m fractured reservoir at a mean depth of 1450 m. Over a 25-year project life, an estimated 14 million tons of the greenhouse gas, which would otherwise be vented into the atmosphere, will be injected and stored in the field's producing formations.

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 distilled prediction

Teacher imitation

Not 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.
