摘要： A slurry and method are disclosed for low damage gravel packing. The slurry comprises a solids mixture comprising a plurality of volume-averaged particle size distribution (PSD) modes such that a packed volume fraction (PVF) exceeds 0.75; a carrier fluid in an amount to provide a solids volume fraction (SVF) less than the PVF of the solids mixture; and a stability additive to inhibit settling of the solids mixture. The method comprises circulating the slurry into a wellbore to deposit the slurry downhole; terminating the slurry circulation for a period of time, wherein the stability additive inhibits settling of the solids mixture; and thereafter circulating the deposited slurry in contact with a surface of a screen. Stability additives disclosed include colloidal particles, hydratable polymer particles, and particles having an aspect ratio above 6.

摘要： 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.

摘要： A completion system that is usable with a well may include a packer, a screen, an isolation valve and an annulus communication valve. The screen communicates well fluid between an annulus of the well and an interior passageway of the completion system. The isolation valve is radially disposed inside the screen to control communication through the screen between the annulus and the interior passageway. The annulus communication valve is located downhole of the packer and uphole of the screen to control communication with the annulus of the well. The packer, screen, isolation valve and the annulus communication valve are adapted to be run downhole as a unit into the well as a single trip completion.
