Abstract:
1. A system for producing liquids and solids from the bottom of a hydrocarbon well where the system comprises: a) a string of production tubing installed in a wellbore where a lower end thereof is near the bottom of the well and where the production tubing defines a gas production annulus outside the production tubing and within the well for gas to be produced to the surface; b) a pump comprising a barrel and a plunger wherein the barrel is attached to the production tubing near the lower end of the production tubing; c) a string of hollow rod disposed within said production tubing such that a tubing annulus is formed around the hollow rod string and inside the string of production tubing and where the hollow rod string is connected to the plunger that is positioned within the barrel of the pump for movement up and down within the barrel and where the liquids exit the top of the plunger into the hollow rod string to be produced to the surface on a downstroke of the pump and the liquid is produced to the surface through the hollow rod; and d) wherein the production tubing includes at least one port for delivering liquid from the tubing annulus via the surface to the gas production annulus.
