Hot to calculate sand settling velocity in heavy oil well?

[cmlpetro]

How do I calculate mininum velocity to lift sand in a heavy oil well?

 

[SNORGY]

Try using the theory outlined in GPSA Section 7 pages 1-4.

[Professional02]

Velocity= Displacement/ Time
Based on this equation, we can calculate the velocity i-e slip velocity of the sand

The slip velocity is dependent on the gel strength of the oil.

 

[TEXWS6]

What about stokes law? This is used quite often hydraulic fracturing simulations.

 

[linas]

The settling velocity (Vs) is calculated using Stoke's law for small particles (Dp< 1mm).

Vs = [(RHOp-RHOf).g.(Dp)^2]/(18.mu)

RHO-density
p-particle
f-fluid
D-diameter
mu-dynamic viscosity of the fluid

All SI units.
