Abstract
Abstract Fracture dominated two-phase flow is important not only for naturally fractured petroleum reservoirs but also for underground disposal of radioactive waste, geothermal hydrotransport, as well as underground water and aquifer flow. In contrast with gas-liquid flow in a single fracture, the flow of heavy oil and water received rather less attention. In this research an experimental apparatus was built to study the flow of water in presence of heavy oil in a smooth-walled fracture and display the different flow patterns under different flow conditions. Also the relationship between different flow pattern and relative permeability curves in a single fracture was investigated. The results were compared with available relative permeability models such as segregated/lubrication model, viscous coupling model, X (stick) curve model, Corey model and T-C model. The comparison leads to the conclusion that there is high interference between the phases flowing through the fracture. The results show that different phases can flow in both continuous and discontinuous forms. Also studying the flow of oil and water under different flow patterns shows that the oil-water relative permeability is not just a function of the fluid saturations but also the fluid properties and flow pattern within the fracture itself.

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 it
