Mobility Control Potential in Geological Sequestration of Anthropogenic Carbon Dioxide using Cheap Soluble Organics as Thickeners and Implications for Interfacial Stability
Bibliographic record
Abstract
Current levels of anthropogenic carbon dioxide in the atmosphere are responsible for global warming at scales not seen before. To mitigate this global warming trend, the Intergovernmental Panel on Climate Change (IPCC) has universally adopted the geological carbon storage option. The technical implication of geological carbon storage is that carbon dioxide with a very low dynamic viscosity will be injected to push formation brine with a high viscosity contrast. Consequently, problems of interfacial instability responsible for poor sweep efficiencies encountered in the petroleum industry’s improved oil recovery projects are inevitable. The petroleum industry has used costly mobility control agents in the form of carbon dioxide thickeners to solve problems of poor sweep efficiency in carbon dioxide enhance oil recovery projects. This experience is useful to the geological sequestration community because carbon dioxide geological storage under supercritical conditions is considered an optimized approach. In this paper, We have reviewed literature to show the solubility of waste organics in supercritical carbon dioxide and the possibility to increase its dynamic viscosity to reduce interfacial instability problems. We have, also, reviewed literature to show sources and availability of cheap soluble organics for carbon dioxide thickening. Our review shows promising sources of these soluble organics. Finally, the technical implications of dynamic viscosity increase on a given geological storage project have been discussed in the context of interfacial stability theories.

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.
