Abstract
Disclosed are flow distribution assemblies for distributing fluid flow through well screens. One flow distribution assembly includes a bulkhead arranged about a base pipe having one or more flow ports and defining flow conduits in fluid communication with the flow ports, a sand screen arranged about the base pipe and extending axially from the bulkhead, a flow annulus defined between the sand screen and the base pipe, and flow tubes fluidly coupled to the flow conduits and extending axially from the bulkhead within the flow annulus, the flow tubes being configured to place an interior of the base pipe in fluid communication with the flow annulus via the flow ports, wherein the flow tubes distribute a fluid through the at least one sand screen at a plurality of axial locations within the flow annulus.
