Abstract
A gravel packing system, method and slurry. The system comprises a blending device to prepare a slurry comprising a carrier fluid suspending first, second and third particulates, wherein the carrier fluid comprises a brine and less than about 2.4 g/L (20 lb per 1000 gallons) of a viscosifier, and wherein the sum of the mass of the particulates is greater than about 2.4 kg/L (20 pounds per gallon), wherein the first average particle volume is between 27 and 3375 times larger than the second average particle volume, which in turn is between 27 and 3375 times larger than the third average particle volume. The system can also include tubing to position a screen in the wellbore and a slurry pump to circulate the slurry from the blending device in the wellbore in any order such that the particulates are deposited in the screen annulus to form a gravel pack.
