Abstract

fetched live from OpenAlex

Abstract Electro-Petroleum, Inc. (EPI) has successfully demonstrated use of DC electrical current for enhanced oil recovery (a process we now call "Electro-Enhanced Oil Recovery", or EEOR) at heavy oil fields in the Santa Maria (California) Basin and the Eastern Alberta Plains. They have also conducted large-scale (1 cu-m sample size) laboratory studies to evaluate unexpected results from these field demonstrations. Dr. G. V. Chilingar, of the University of Southern California, publicly advocated using a similar technology in the 1960’s. Several successful applications of similar technology have been claimed, in the Former Soviet Union. Field studies in California have demonstrated up to a ten-fold increase in oil production from a field containing 8° API gravity oil. Recent research has demonstrated that the EEOR process is also capable of cold cracking of heavy oil in-situ, resulting in lighter produced oil and increased reservoir pressures. EEOR can function at depths below 10,000 feet, well below the 2,500 ft. practical limit for steam flood operations. Observed changes in the produced fluids include:Increased oil production rates.Reduced produced oil viscosity increased API gravity).Reduced water cut.Reduced H2S production.Increased gas production.Increased produced gas energy (heavy gas) content.Reduced PAH production. All of these observed fluid chemistry changes can be explained by the use of DC electrical technology.

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.
