Talk to Wier Pumps who make them.....

good luck!!
RE: HSP - Hydraulic Submersible Pumps
Having spoken with my pal who worked on Captain, it seems that all but one of the HSPs on Captain were subsea, with no pump failures after about three years when he left he project (one well failed due to non pump reasons) and with availabilities up at around 100%. They've pumped up to 75% gas continously and even managed 100% gas intermittently without gas locking. Issues include the surface equipment for the power fluid, large size of the completion with one string for the power fluid and one for the produced fluids (i.e you need 9-5/8" through the reservoir), but other advanteges in additon to the gas handling capbailities and the lack or subsea electrical connections is the fact that he pump iself is pretty short- you won't be handling 180ft of pump stages or something stupid.
So if you've got a high GOR crude, they seem to be a real alternative to ESPs, but as an alternative to gas lift, I'd guess the real advantage is no need for a gas compressor, and that's about it.
Wier Pumps make them, and can give you a lot more information and engineering assistance.
