Abstract

Completion system (120) has an auto-flow crossover assembly (10), with a plurality of selectable electrical submergible pumps (ESP) (114, 116), e.g. As a dual primary and back-up ESP system, the assembly including a tubular body (38), within which is an annulus (44) housing a shunt valve (50) with radial outlets (58) alignable with radial inner ports (75) in an inner moveable valve sleeve (76) surrounding part of a throughbore (46), wherein, dependent upon pump selection, and fluid pressure acting upon a valve poppet (81) on the sleeve to lift same from a valve seat (60), the radial ports (58, 75) will be aligned or not permitting alternative flow path configurations in which even with both pumps turned off at least one pump is protected from foaling with detritus, and during switch over between ESPs the auto-crossover system protects the "off" pump.
