Abstract
A submersible pump assembly has a tubular intake housing containing intake housing ports. A gas restrictor is carried around the intake housing. The gas restrictor is an eccentric sleeve with a semi-cylindrical portion with a centerline coincident with the axis of the pump and extending around an upper portion of the intake housing. A counterweight portion connected with the semi-cylindrical portion has an outboard area farther from the centerline than the semi-cylindrical portion. A weight bar may be mounted to the counterweight portion. The gas restrictor is free to self orient relative to the intake housing due to gravity while the pump assembly is in the horizontal section of the well, with the semi-cylindrical portion overlying and blocking at least some of the intake housing ports on an upper portion of the intake housing.
