Abstract
Many petroleum discoveries which have heretofore been regarded as intractable owing to the immobility of the petroleum can be economically recovered by a process involving local visbreaking of the intractable petroleum in order to produce a medium/heavy cracked gas oil which is injected into a subterranean formation of the intractable petroleum in order to recover the petroleum.
