I want to research an eductor pump to lift a mixture of natural
gas, water and crude oil from a well.  The well depth will vary, as
will the height of standing fluid and the specific gravity of the
crude oil.  I envision using compressed natural gas to power the
suction mechanism.  The % mix of water, crude oil and natural gas
being lifted will vary.  I envision using a natural gas powwered
compressor to compress the gas.  The lifted
materials will be separated using a separator and the natural gas can
be recompressed for reuse.  Any produced excess gas can be used to
power the compressor and/or sold.  I want to obtain calculations to
calculate pressure & volume of the gas required to pump, as well as
lift height, pumped volumes, etc.
