Abstract

fetched live from OpenAlex

Abstract Primary production has been carried out for more than 30 years from large overthrusted carbonate structures along the north coast of Cuba between Havana and Varadero. Long reach horizontal wells, with open hole completions, are used and extensive logging suites, including FMI, have been collected and analyzed. A huge amount of oil is held within the tight matrix but currently most of the produced oil is likely from macro and micro fractures, and breccia or vuggy porosity. It is postulated that primary production is supported by secondary gas in the fractures and "foamy oil". The EXODUS simulator has been used to model the system in dual porosity mode demonstrating the coning of gas and water in the fracture system and production from a "rim" of oil in the fractures at the level of the wells. Field observations and well performance also demonstrate the presence of gas in the fracture system and the high permeability necessary to drain the viscous oil.

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.
