    摘要: A composition and method are disclosed. The composition includes a carrier fluid and a solids mixture combined to form a slurry, wherein the solids mixture comprises a plurality of volume-averaged particle size distribution (PSD) modes, wherein a first PSD mode comprises solids having a volume-average median size at least three times larger than the volume-average median size of a second PSD mode such that a packed volume fraction of the solids mixture exceeds 0.75, and wherein the solids mixture comprises a degradable material and includes a reactive solid. The method includes circulating the slurry through a wellbore to form a pack in a fracture and/or a screen-wellbore annulus; degrading the degradable material to increase porosity and permeability of the pack; and producing a reservoir fluid through the permeable pack.

    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.

A fluid flows through the first port to fracture a first zone, and the first port can be closed with the shifting tool after the first zone has been fractured. A second port can be opened in a second valve assembly with the shifting tool after the first port has been closed, wherein the second valve assembly is positioned below the first valve assembly. The fluid can flow through the second port to fracture a second zone, and the second port can be closed with the shifting tool after the second zone has been fractured.
