Centraflow uses in-house CFD capabilities to model ‘well-specific’ scenarios, taking into account:
•Average hole diameter (under-gauge or over-gauge).
•Centralization scheme and associated stand-off.
•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.
•Optimal spacing for fluid diverter tools on the casing.
