... correlations are needed also for relative permeability behavior of the three fluids with the pressure. These correlations can be generated by the multi-regression analysis of PVT data and relative permeability curves. The second represents developing the analytical models for the flow regimes that could...

... of these parameters. Flow parameters such as flow regime and wall shear are critical for accurate corrosion prediction since these parameters affect the mass transfer of corrosive species and stability of corrosion product scales. Corrosion models that can accurately simulate the field brine chemistry, production...

Therefore, all these variables should be evaluated in the proposed methodology to optimize the test, which is the key difference between...

...Flow Regimes In steady-state single-phase flow in a pipe, the classification of the flow is whether the flow is laminar or turbulent. Laminar flow is when the particles in the flow move axially in one direction. Turbulent flow is when the particles in the flow move axially and radially...
