Abstract
Abstract Downhole electrical heating has proven as an attractive alternative of lowering the oil viscosity by raising the temperature in the formation. Because reservoirs with characteristics such as extremely low permeability, very thin pay-zone, and extra-heavy oil are generally not feasible for steam injection based Enhanced Oil Recovery (EOR) techniques, and the application of low- frequency Electrical Resistance Heating (ERH) has been demonstrated to limit the heating rate as well as the production rate. Hence, high frequency Electromagnetic Heating (EMH) has been chosen as a potential candidate to a reservoir for which other thermal recovery techniques are not suitable. This study presents both an oil single phase radial flow and oil-gas two-phase linear flow EMH model with COMSOL. Result shows that EM heating is practicable and cost effective under certain constraints in the real field. Parametric study indicates that the cumulative oil production achieved by EMH can be enhanced by a similar EOR approach called Single Well Steam Assisted Gravity Drainage (SW-SAGD) simulated in STARS for reservoirs with the above mentioned characteristics.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
