What is a Sand Screen? (with picture) - Info Bloom

A sand screen is a type of filter used to separate sand particles from other materials. It is often used in oil sands production, and allows users to harvest oil products without also collecting the sand nearby. These screens are also used on a smaller scale in many industrial and mining applications to separate sand

3M™ Ceramic Sand Screens for Oil and Gas Operations

Sand control is a constant problem in soft or weak geological formations. Thousands of feet downhole, formation sand can choke oil or gas production – and if it isn’t filtered out, this sand can damage equipment downstream. 3M™ Ceramic Sand Screen Systems are engineered to simplify complex sand control methods.

2015-6-29  The slot width, or the screen gauge, is sometimes sized to be equal to the formation sand grain size at the 10-percentile point of the sieve analysis. The theory is that because the larger 10% of the sand grains will be stopped by the openings of the screen, the larger sand will stop the remaining 90% of the formation.
