US Patent 10400554 Longitudinally offset partial areas screens for well assembly

A downhole assembly can include screens along a length of a tubular member. Screens covering differing portions of a cross-sectional area of the tubular and less than an entirety of the cross-sectional area can be offset from one another along a length of the tubular. Fluid flowing through an area not covered by a first screen can encounter an area covered by an offset screen. If the offset screen is blocked with accumulated debris, fluid may pass the offset screen by passing through an area not covered by the offset screen.
