Abstract
Systems and methods for removing sand from fluid in a subterranean hydrocarbon development well include producing a cyclonic flow pattern of a sandy fluid of the subterranean well within a wellbore of a subterranean well with tangentially formed openings along a fluid flow path of the sandy fluid. The cyclonic flow pattern causes sand traveling in the sandy fluid to fall downhole as separated sand, and causes a de-sanded fluid stream to be directed uphole towards a production tubing. The de-sanded fluid stream is produced through the production tubing. The separated sand is collected proximate to a suction end of a progressing cavity pump. The progressing cavity pump is operated so that the separated sand flows through the progressing cavity pump and out a discharge end of the progressing cavity pump, to produce the separated sand through a sand discharge tube.
