following monarks earlier question thru...
the next part would also be why the west-east spread of gas-condy-oil
and why ce1 has so much condensate...
gas, condy and oil was originally formed in the thick western part of the montney
and then migrated east
oil went first, then condensate and gas
the migration went furthest and with most quantity where there was good quality porous rock
and thats what ce1 has on its land and just to the west of it
end result, condensate moved in larger amounts thru more porous rock towards the east, and into ce1 lands
see yellow condensate movement west at top in this figure

The recognition of widespread gas-condensate migration in this study adds to the complex history of multiple episodes of internal (intraformational) hydrocarbon migration that is emerging for the Montney unconventional petroleum system (Fig. 7), including an early oil migration episode during burial (green arrows)18,19,20, and a late methane-rich gas episode (red arrows)9,10,11,12,13largely during basin uplift15,16,17(Fig. 2). Gas-condensate generation mostly post-dated the early episode of oil migration, and occurred when increased burial depths and temperatures led to thermal cracking of the originally migrated oil. Internal migration of gas-condensate on a regional scale was driven by the significant pressure difference that existed between deeper and shallower Montney zones. Gas-condensate migrated preferentially to oil due to its much lower viscosity (by one to two orders of magnitude)8. The degree of gas-condensate migration was likely not regionally uniform (Fig. 7, yellow arrows) and appears to have extended further up-dip in part of the North Montney area12. The migration of late-stage methane-rich gas is thought to have been influenced by both stratigraphic and structural trends13,15,16,17and a similar interpretation is likely applicable to the earlier migration of gas-condensate. Secondary migration of gas-condensate in the WCSB, it should be noted, is not unique to the unconventional petroleum system of the Triassic Montney Formation, and is known to have occurred in many conventional reservoir zones from Devonian to Cretaceous in age1,2.
