Abstract

fetched live from OpenAlex

Abstract Wax deposition is a worldwide problem for the upstream petroleum industry. Considerable resources are expended every year on trial-and-error type chemical treatment options. In a laboratory setting chemical treatments are often optimized using viscosity and pour point measurements. Viscometry and pour points can only measure bulk properties. Cross-Polarized Microscopy (CPM), however, has been shown in previous work to be a useful tool to determine individual wax crystal size and morphology. Thus, in this work CPM was used to evaluate the effectiveness of wax inhibitor treatments for paraffinic and naphthenic base oils by monitoring the morphology and size of the wax crystals before and after the application of the chemical treatments. It has been demonstrated that there is a statistically significant reduction in wax crystal size after the wax treatment. Furthermore, the observations of the wax morphologies through CPM have demonstrated that the chemical treatment effectively inhibits wax crystal growth for both macrocrystalline (paraffin) and microcrystalline (naphthene and iso-paraffin) waxes. In addition to viscosity and pour point measurements CPM has been demonstrated to be a valuable tool to the optimization of wax-treatment options.

Teacher imitation

Not 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.
