Abstract
A method is disclosed for low damage gravel packing. The method includes combining a carrier fluid, a first amount of particulates, and a second amount of particulates into a slurry. The first amount of particulates have a first average size distribution and the second amount of particulates have a second average size distribution, and the first average size distribution is at least three times larger than the second average size distribution. The slurry includes particles which are at least partially degradable material, and with reactive solid constituents. The reactive solid reacts with the degradable material and/or a hydrolysis product of the degradable material. The method further includes positioning a screen in a wellbore, and circulating the slurry through the wellbore such that the first amount of particulates and the second amount of particulates are deposited on an outer surface of the screen.
