Pretty simple explanation the upper reservoirs are at hydrostatic pressure (or "normally pressured" in oil field parlance, with heavy oil they will have zero pressure at surface and with no ability to pump no need for a separator....why people on this forum expected natural flow to surface is way beyond my knowledge I'm an engineer not a psychologist! It will flow with a pump....and yes pumping is 100% normal in the industry in this sort of reservoir setting they can use Beam Pumps (Nodding Donkeys in the US or PferdKopf if you have worked Germany), though I think here they might look at surface motor Progressive Cavity Pumps (PCP a sort of elastomeric screw pump) to get a better drawdown, though if the Inflow characteristics are OK they could go for big rates an Electric Submersible Pumps (ESP). It will all be down to the flow characteristics, equipment availability (have Russian or Chinese) and the economics.

Like you're thinking, worked for a mob that had Heavy Crude very low WAT was like vegemite couple wells early on flowed to surface but not for long ran in ESP's and been flowin oil since 2004 done Millions of barrels.
