Experimental Study of Sand Distribution among Perforation ...

When the pumping rate is 30 gallons/minute, more sand will accumulate at the first cluster perforation, along with the increase of sand concentration. At a higher pumping rate, more sand will enter into the last perforation cluster. At the pumping rate of 80 gallons/minute, a large portion of sand deposited down to the last perforation cluster.
