Particle-size distribution: the gate before sizing any desander.

The particle-size distribution sets the cut size the desander has to reach, and the basis is stated per duty. That is why it is the sizing gate: without it, any efficiency figure is a guess.

If there is no disposal route, there is no project.

The Sep-iSYS™ Desander sits in the flowline and removes produced sand from the full wellstream at line pressure, before it reaches the choke, the first bend and the separator.

Two further questions decide whether a project exists at all. The solids have to go somewhere: if there is no disposal route, there is no project. And catastrophic sand is a downhole problem; surface desanding manages a rate, it does not contain a formation failure.

If you do not have a particle-size distribution, we can test for it. With it, send the sand production rate, the gas, oil and water rates, pressure, temperature and fluid properties, the allowable pressure drop and design class, and the space and sand-disposal route.
