System for pumping fluids from horizontal wells
This patent describes apparatus for separating gas and liquid and pumping the liquid from a horizontal well. It comprises: a first and second string of tubing, each string having an upper and a lower end, the first string having an inlet port and the second string extending to the surface of the earth; a shroud having an upper end and a lower end and a vent for venting gas outside the shroud, the shroud enclosing a pump and motor connected thereto for driving the pump and enclosing a liquid-gas separator means having an inlet fluid port and an outlet port for gas upstream of the pump; the vent of the shroud being above the pump so as to allow discharge of the gas from the outlet port of the separator means through the vent; means for attaching and hydraulically sealing the upper end of the shroud and the pump to the lower end of the second string of tubing; and means for attaching and hydraulically sealing the lower end of the shroud to the upper end of the first string of tubing.
