Abstract
An apparatus for activating chambers of downhole hydraulic screens. The apparatus comprises an outer sleeve, an inner sleeve, and a flow path. The outer sleeve is coupled to one hydraulic screen on one end and another hydraulic screen on another end. The inner sleeve couples to base pipe at both ends. The flow path is an annulus defined between the outer diameter of the inner sleeve and the inner diameter of the outer sleeve. Hydraulic seals are formed at the interfaces between the inner sleeve and base pipe and the outer sleeve and hydraulic screens. In practice, the assembled apparatus and hydraulic screens are ran downhole to a production zone using production tubing and a running tool. Fluid from the surface is pumped into the production tubing, diverted therefrom, and into chambers of the hydraulic screens using the flow path to conduct fluid between the hydraulic screens.
