Geologic Reservoir Characterization and Evaluation of the Petrocedeño Field, Early Miocene Oficina Formation, Orinoco Heavy Oil Belt, Venezuela
Bibliographic record
Abstract
Abstract More than 12 yr of field development and production at Petrocedeno (formerly Sincrudos de Oriente C.A.) in the Orinoco Heavy Oil belt, Venezuela, have generateda detailed picture of the three-dimensional (3-D) reservoir architecture, static and dynamic properties, and sedimentology of this important deposit. The Petrocedeno project is located along the foreland bulge on the south side of the eastern Venezuelan foredeep basin. Its hydrocarbon is derived mainly from marine source rocks from the early Paleocene to the Miocene; long-distance secondary migration occurred toward the foreland bulge. Traps are stratigraphic in nature, and lateral seal is provided by a combination of biodegraded hydrocarbons and increasingly immobile crude oil. A dense network of wells has enabled the construction of high-resolution static and dynamic models of the fluvial and deltaic reservoir units in the hydrocarbon-bearing lower member of the Oficina Formation.

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.
