1. A system for protecting an Electrical Submersible Pump (ESP) string having a pump and a motor, the system comprising:
an intake tube having a first and second end; wherein the intake tube is coupled to and extends below an inverted shroud through a gas pocket and into a liquid from a hydrocarbon reservoir; wherein the first end opens below the inverted shroud and within the liquid; wherein the second end opens within the inverted shroud and to the ESP; wherein the intake tube serves as the only fluid opening within the inverted shroud; and
the inverted shroud coupled to the intake tube;
wherein the intake tube is not directly coupled to the pump and the motor; wherein a casing is adjacent to the inverted shroud to form an annulus; wherein the inverted shroud and casing are arranged in close proximity to one another such that the gas pocket accumulates below the inverted shroud; wherein the accumulated gas temporarily halts the flow of the liquid past the gas and into the annulus between the inverted shroud and the casing; wherein the casing portion adjacent to the inverted shroud is not perforated.
