Estimating the term…
A production well penetrating a subsurface oil-bearing formation utilizes perforations in well casing through which formation fluids enter the well. Production tubing extends from the surface of the earth to a position below such perforations. A pump is positioned at the lower end of the tubing for pumping the formation fluids upwardly through the tubing to the surface of the earth. An agitating unit is positioned below the pump and is rotated in the formation fluid within the well to insure that formation fines entrained in the formation fluids are fluidized for production to the surface of the earth rather than settling out of the formation fluids within the well.
Apparatus for fluidizing formation fines entrained in formation fluid entering a production well through perforations in well casing penetrating a subsurface oil-bearing formation, comprising:
