摘要： A method of treating a subterranean formation penetrated by a wellbore is carried out by forming a treatment fluid comprising an aqueous carrier fluid and a solid-form polyimide homopolymer or copolymer capable of hydrolyzing to form polycarboxylates and/or polycarboxylic acids. The treatment fluid is introduced into the formation through the wellbore. In another method, a treatment fluid comprising an aqueous carrier fluid, a solid-form polysuccinimide homopolymer or copolymer and at least one of a viscosifying agent, proppant and an acid capable of dissolving materials of the formation is formed. This is introduced into the formation through the wellbore. A method of treating a sandstone-containing formation penetrated by a wellbore may also be carried out by forming a treatment fluid comprising an aqueous solution containing a hydrogen fluoride source, ammonium hydroxide and at least one of a polyimide and a polycarboxylate, which is introduced into the formation through the wellbore.

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： Methods for creating packers at a desired location or locations within a wellbore for use in specific wellbore applications. A slurry of fluid medium and hydrolysable particulate matter is flowed to a downhole position and dehydrated. At this location, the particulate matter is released from the fluid medium and accumulated. The continual accumulation of the slurry and consequent deposition of particulate matter creates a degradable packer at the desired location within the wellbore. The particulate matter may be formed of an acid particle which may be removable, degradable, or hydrolysable under certain conditions of temperature, time, hydration, pH, and/or pressure. Either simultaneous with or subsequent to a wellbore activity, the packer is partially or completely removed from the wellbore.

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.
