A method of enhancing the flow of hydrocarbon fluids from small flow conduits ( 12 ) in a subterranean reservoir rock formation ( 10 ) that have traditionally not been propped in association with a fracturing treatment of the formation ( 10 ), the method including the steps of introducing a first pressurized fluid into the formation at a pressure that is sufficient to expand the pre-existing small flow conduits ( 12 ) and introducing into the pressure-expanded small flow conduits ( 12 ) a first portion of a relatively small particulate propping agent ( 16 ); simultaneously with the fracturing of the formation, or immediately thereafter, introducing a second portion of a relatively small particulate propping agent ( 16 ) into expanded pre-existing small flow conduits and into any new small flow conduits that are formed by the fracturing of the formation; and reducing the hydraulic pressure on the formation, whereby the small flow conduits are held open by propping agent particles.
