Volume ,fracturing, is an effective way to generate a larger number of fractures. Field application indicates that volume ,fracturing, treatment can form a much greater reservoir stimulation volume. Daily oil production in the volume-,fracturing,-treated wells can be more than twice as high as that in the conventional-,fracturing,-treated wells. Full article
