History of the Parentis Oil Field Discovery, Aquitaine, France
Bibliographic record
Abstract
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.

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.
