Hot to calculate sand settling velocity in heavy oil well?

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

RE: Hot to calculate sand settling velocity in heavy oil well?

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

RE: Hot to calculate sand settling velocity in heavy oil well?

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.

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

RE: Hot to calculate sand settling velocity in heavy oil well?

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.
