An apparatus, system and method for reducing gas intake in horizontal submersible pump assemblies are described. A horizontal electric submersible pump (ESP) system for pumping gaseous fluid comprises a multi-stage centrifugal pump, an electric motor operatively coupled to the centrifugal pump, and an intake section upstream of the pump comprising a tapered core further comprising a sloped outer surface extending between a downstream side and an upstream side, a first intake port for the intake of well fluid in an ESP assembly, the first intake port located on a top portion of the tapered core and proximate to the downstream side, a gravity-actuated closing member moveably attached on the sloped outer surface, wherein the gravity-actuated closing member closes the first intake port, and a second intake port located on a bottom portion of the tapered core, the second intake port open to the well fluid. |
