Categorical Boosting‐PSO: A SHAP‐Interpretable Hybrid Framework for High‐Fidelity Wax Appearance Temperature Prediction in Subsea Pipelines

Engineering Reports
Wax deposition in subsea pipelines poses significant flow assurance challenges, yet accurate wax appearance temperature (WAT) determination remains constrained by resource intensive experiments and the absence of a robust, interpretable machine learning ...

Assessing the Biological Inhibitors Effect on Crude Oil Wax Appearance Temperature Reduction [PDF]

Journal of Petroleum Science and Technology, 2018
To assess the effect of micro-organisms on the reduction of wax appearance temperature (WAT) of waxy crude oil, some appropriate strains were obtained from contaminated samples exposed to hydrocarbon compounds for a long time.

Measurement of the wax appearance temperature of waxy oil under the reservoir condition with ultrasonic method

Petroleum Exploration and Development, 2014
To solve the problem that wax appearance temperature (WAT) acquired by conventional method is not suitable and effective to the subsurface live crude oil and dark oil, a way to measure the WAT of crude oil varying in properties is explored using the ...

Investigation of adsorption behaviors of paraffin waxes on iron, iron oxide, and iron III oxide pipeline's internal surfaces using adsorption locator model

Petroleum Research, 2022
Wax deposition in pipelines leads to pressure drop, reduced effective cross-sectional area, and blockages. Although mathematical models and experimental loops were used to model wax precipitation on pipeline surfaces, its prediction at molecular levels ...
