Abstract:
Bidirectional flow control device for attachment to a tubular member including a nozzle insert comprising a first sealable surface, the nozzle insert comprising a nozzle passage, and a second sealable surface for mating with the first sealable surface, and a first biasing member seat; a cover plate positioned adjacent the first end of the nozzle insert, the cover plate comprising a production orifice and a plurality of stimulation orifices in fluid communication with a plurality of stimulation passages, the cover plate further comprising a second biasing member seat and a biasing member positioned between the first biasing member seat and the second biasing member seat, the biasing member to exert a biasing force to place first sealable surface and second sealable surface in sealing engagement when internal tubular pressure is below a set-point value.
