1. An intake section of an electric submersible pump (ESP) assembly, comprising:
an intake housing generally cylindrical in shape and comprising an outer surface, an inner surface, an uphole end adjacent a pump section, and a downhole end adjacent a seal section;
an intake head generally cylindrical in shape and comprising an outer surface, an inner surface, and a first bushing surface coupled to the uphole end of the intake housing and a base of the pump section; and
an intake base generally cylindrical in shape and comprising an outer surface, an inner surface, and a second bushing surface coupled to the downhole end of the intake housing and a header of the seal section,
wherein the intake housing further comprises a proportional pattern of a plurality of inflow ports having one or more of the following features:
the proportional pattern comprising a density of inflow ports that increases as the pattern of ports moves axially away from the intake head; and
the inflow ports comprising i) a hole cross-section, ii) an outer surface shape, iii) an inner surface shape, iv) a hole tilt angle, v) or combinations thereof, and
wherein the hole tilt angle starts i) greater than or ii) about perpendicular to a central axis of the intake housing and decreases as the pattern moves axially away from the intake head toward the intake base.
