Novel Organic Solids Deposition and Control Device for Live-Oils: Design and Applications
Bibliographic record
Abstract
A novel laboratory-scale flow assurance tool termed an “organic solids deposition and control (OSDC)” device has been developed to assess the potential for and severity of organic solids deposition problems from hydrocarbon fluids at realistic production and/or transportation conditions. The OSDC device is a shear cell based on Couette−Taylor flow with a cylindrical geometry. The shear cell geometric parameters are optimized to maximize the Reynolds number. The OSDC device mimics the typical pipeline production conditions of temperature, pressure, composition, turbulence, shear rate, surface type, and roughness. These key parameters can be accurately and independently controlled, allowing the deposition tests to be conducted over a wide range of conditions. Deposition tests were performed on live waxy and asphaltenic oils. Reproducible deposits have been generated under consistent test conditions. Wax deposition rates from OSDC are comparable to those found in pilot-scale flow loops while using orders of magnitude less fluid.

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.
