Abstract

fetched live from OpenAlex

Summary In 1951 the Standard Oil of New Jersey was granted at 100% a permit covering a large portion of North Aquitaine, with South Aquitaine being reserved for two French state-owned companies. The first well drilled, Mano 1, in 1953 proved dry but was lucky enough to find a 670 m thick section of Lower Cretaceous and notably with some weak shows. In 1954 for its second exploration well the Standard Oil took the risk of drilling Parentis 1 even if lacking control to the west under a lake … In March 1954 oil flowed from Aptian and Barremian dolomites, a karstified and highly fractured reservoir. Parentis became at the time the biggest producer in western Europe and Esso-Rep was created to exploit the field. Recoverable reserves approach 250 Mbo. With the progressive exhaustion of the volumes produced, Esso-Rep decided to cease its activities and in 1997 sold the field to the Canadian company Vermilion.

Not 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.
