CFD - Why we use it

Well Specific Computational Fluid Dynamics (CFD)

What is Computational Fluid Dynamics?

CFD is a numerical simulation method based on physics and mathematical equations that allows to model and simulate liquid, gas and particle motion. CFD analysis provides detailed information on all fluid processes such as velocity, pressure, temperature, turbulence, multiphase mixtures and fluid-structure interactions. 

The simulations will give a virtual result based on the numerical methods and the implemented physics. The results can be extremely accurate, as long as the correct input data is used. 

Why use CFD?

Centraflow uses in-house CFD capabilities to model ‘well-specific’ scenarios, taking into account:
•Average hole diameter (under-gauge or over-gauge).
•Wellbore inclination.
•Centralization scheme and associated stand-off.
•Flow rates.
•Mud, spacer & cement properties.
•Distance taken to return to high-side steady flow.

The effect of downhole fluid diversion can then be assessed:
•Velocity inversion effects and flow regime.
•Distance taken downstream to return to high-side steady state flow.
•Turbulence effects.
•Optimal spacing for fluid diverter tools on the casing.
