N'usoro mmepụta mmanụ na gas na Liaohe Oilfield, enwere akụrụngwa hydrocarbon dị ka gas akọrọ na naphtha. Iji usoro a mepụta hydrogen nwere ike ime ka ojiji akụrụngwa dịkwuo elu. Ọzọkwa, isi ihe dị na gas eke ejikọtara ya bụ methane, nke enwere ike ịgbanwe ka ọ bụrụ hydrogen site na uzuoku hydrocarbon, yana ịdị ọcha mmepụta dị elu na arụmọrụ mmepụta dị elu.
