Investigación para sísmica 4D de las variaciones de las propiedades petrofísicas y de la viabilidad técnica en los yacimientos de crudos extrapesados espumantes
Bibliographic record
Abstract
La sísmica 4D es una herramienta geofísica moderna para la gestión de la explotación de los grandes yacimientos petrolíferos. Los petróleos extrapesados constituyen recursos energéticos muy abundantes, aún no explotados ampliamente, cuyos yacimientos no han sido considerados, hasta ahora, buenos candidatos para la Sísmica 4D. Esta Tesis muestra que, cuando los petróleos extrapesados tienen propiedades espumantes ("foamy oils"), tal como ocurre en la mayoría de los yacimientos de la Faja Petrolífera del Orinoco y de las Arenas Petrolíferas de Alberta, si es viable aplicar Sísmica 4D. La demostración se basa en que las disminuciones de los atributos sísmicos de las formaciones de los yacimientos, que ocurren durante la producción de los petróleos espumantes, son superiores a los valores mínimos considerados como detectables por la Sísmica 3D actual. Estas disminuciones importantes se deben a la presencia de burbujas de gas dispersas en la masa de crudo durante gran parte de la explotación.

How this classification was reachedexpand
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.
