A Techno-Economic Analysis of Coupling Enhanced Hydrocarbon Recovery and CO2 Storage in Gas Condensate Reservoirs
Bibliographic record
Abstract
Coupling enhanced gas (EGR) and condensate (ECR) recoveries with CO2 storage could potentially maintain fossil fuel supply and reduce CO2 emissions to the atmosphere. This paper evaluates the techno-economic potential of simultaneous EGR, ECR and CO2 storage in gas condensate reservoirs. We demonstrate that, for a closed gas condensate reservoir, injecting CO2 later in production life is more profitable than early injection. This is because it delays CO2 breakthrough at the production wells while enhancing gas and condensate production. In contrast, for a bottom-water drive gas condensate reservoir, we find that early CO2 injection minimises water influx from the underlying aquifer. This maximises incremental gas and condensate production and CO2 storage in the reservoir.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
