A passive collection and pneumatic lifting system located in a well
comprising a pneumatic tube, a fluid tube mounted within the pneumatic
tube creating an annulus and a jet barrel chamber formed between the
pneumatic tube and fluid tube in fluid communication at the zone to be
recovered. A valve in the jet barrel in communication with the jet barrel
and the zone to be recovered for allowing passive flow of product to be
recovered into the jet barrel for collection therein and for closing upon
the introduction of pneumatic fluid pressure by a pneumatic pressure
generator to generate pneumatic fluid pressure sufficient to drive the
product collected in the jet barrel up hole for recovery. A seal is
located below the valve for sealing the product zone in the well from
flow except through the valve.
