The Complete Frac Sand Production Process | Pontotoc

We've reached the frac sand production stage where commercial experts have already removed sandstone from wells and drilling sites. Next, we have to wash the sand. Sand grains are cleaned to remove unwanted clay particles and silt. Clean sand is then pumped to settling tanks where flocculants are added to remove the remaining particles.

A Short Review of Sand Production Control

Sand production is usually linked with a weak reservoir formation. Sand production may be inevitable in unconsolidated sandstone formation with permeability between 0.5 to 8 darcies (Jon carlson et al., 1992) In addition, reservoirs with low formation strength (<1000 psi) are most susceptible to sand production (Salama, 2000).
