Evaluation of Two New Self-assembly Polymeric Systems for Enhanced Heavy Oil Recovery
Bibliographic record
Abstract
In enhanced oil recovery (EOR), the stability of polymeric systems in harsh reservoir conditions is significant. A proof of concept research on the application of supramolecular self-assembly for EOR is presented in this paper. The motivation was to acquire new insights on the effectiveness of these extended polymolecular assemblies with improved salinity and hardness tolerance and viscoelastic properties for EOR. The formation of these self-assemblies relies on noncovalent interactions that hold them together. The performance of two self-assembly systems derived from a partially hydrolyzed polyacrylamide (SAP-HPAM) and xanthan gum (SAP-XG) for heavy oil recovery was established and compared to the performance of a commercial hydrophobically modified polyacrylamide (HMSPAM). The SAP-HPAM produced 20% higher incremental heavy oil recovery than the baseline HPAM; while the SAP-XG does not show suitable propagation within the porous media. These experimental results provide new helpful insights for the technical and cost-effective optimization of these self-assembly compositions for EOR applications.

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.
