A submersible pumping system includes a pump, a motor that drives the pump and a separator assembly. The separator assembly is for separating gas from the fluid and includes an intake and a vent above the intake. Fluid enters the separator assembly at the intake and the vent returns a portion of the fluid into wellbore for recirculation into the intake.

What is claimed is: 1. A submersible pumping system for producing a fluid from a wellbore, comprising: a pump; a motor that drives the pump; and a separator assembly for separating gas from liquid in the fluid, the separator assembly comprising: an intake where fluid enters the separator assembly;

What is claimed is: 1. A submersible pumping system for producing a fluid from a wellbore, comprising: a pump; a motor that drives the pump; and a separator assembly for separating gas from liquid in the fluid, the separator assembly comprising: an intake where fluid enters the separator assembly; and a vent above the intake that returns a portion of the gas and liquid in the fluid into the wellbore for recirculation into the intake. 2. The submersible pumping system of claim 1, wherein the separator assembly further comprises: a shaft rotated by the motor; and an inducer rotated by the shaft. 3. The submersible pumping system of claim 1, further comprising an orifice positioned between the vent and the pump. 4. The submersible pumping system of claim 1, further comprising a neck, wherein the vent is disposed in the neck. 5. The submersible pumping system of claim 1, wherein the vent includes a one-way valve. 6. A separator assembly for use with a pump and a motor in a wellbore, the separator assembly comprising: an intake where fluid enters from the wellbore; and a vent above the intake that returns a portion of the gas and liquid in the fluid into the wellbore for recirculation into the intake. 7. The separator assembly of claim 6, further comprising: a shaft rotated by the motor; and an inducer rotated by the shaft. 8. The separator assembly of claim 6, further comprising an orifice positioned between the vent and the pump. 9. The separator assembly of claim 6, further comprising a neck that includes the vent. 10. The separator assembly of claim 6, wherein the vent is a one-way valve. 11. A method for separating gas from a wellbore fluid that includes both liquid and gaseous components, the method comprising: moving the wellbore fluid through a separator assembly; diverting a portion of the wellbore fluid from the separator assembly into the wellbore, where gaseous components separate from liquid components in response to gravity; and recirculating the diverted wellbore fluid into the separator assembly. 12. The method of claim 11, further comprising a step of increasing the pressure of the wellbore fluid in the separator assembly. 13. The method of claim 11, further comprising a step of pumping the portion of the wellbore fluid that is not diverted from the separator assembly through production tubing to a wellhead. 14. The method of claim 11, further comprising a step of regulating a flow of the wellbore fluid that is not diverted. 15. The method of claim 11, further comprising a step of restricting the flow of fluid into the separator assembly.
