Screening

In operation, sewage flows though the inclined screen, approaching from the upstream side and after passing through the screen, departing on the downstream side. The screen is periodically raked by a mechanized comb system which is actuated either by level switches mounted in the channel upstream of the screen or by time clock.

Sand control techniques

 · When this technique is used to control formation sand, the slotted liner or screen diameter should be as large as possible to maximize inflow area and minimize the amount of resorting that can occur. Another potential disadvantage of both slotted liners and screens in high-rate wells is the possibility of erosional failure of the slotted liner or screen before a bridge can form.

What is a Sand Screen? (with picture)

 · A sand screen is often used to line the diameter of the bore, allowing oil and natural gases to filter through while keeping sand out of the bore hole. This helps prevent sand from getting into the drills, where it can slow production, or even render the drilling equipment unusable.

 · Slurry sand retention tests use low sand concentrations pumped through the screen to prevent segregation of the formation sand before it reaches the screen. The sand is suspended in a slurry which is a viscous polymer solution and is added to a high-flow-rate brine stream by a displacement pump to dilute the sand concentration flowing onto the screen.
