Downhole solids handling in wells

A solids collector is disposed at an end of a tubing in a wellbore. At a top of the solids collector, a reservoir fluid stream carrying solids is separated into a solids-liquid stream that is reversed into an annulus in the solids collector and a gas stream that continues to move uphole in the wellb...

Zusammenfassung:	A solids collector is disposed at an end of a tubing in a wellbore. At a top of the solids collector, a reservoir fluid stream carrying solids is separated into a solids-liquid stream that is reversed into an annulus in the solids collector and a gas stream that continues to move uphole in the wellbore. At an end of the annulus in the solids collector, the solids-liquid stream is separated into a liquid stream that moves up the tubing and solids that are accumulated in the solids collector.
