    摘要: The present invention provides improved methods of placing proppant in fractures formed in a subterranean zone to prevent the subsequent flow-back of the proppant with fluids produced from the zone. The methods are basically comprised of the steps of depositing a mixture of hardenable resin composition coated proppant and uncoated proppant in the fractures and then causing the resin composition to harden into stationary permeable masses in the fractures.

    摘要: Methods of using water-soluble hydrophobically modified polymers to treat intervals of a subterranean formation having variable permeabilities. An exemplary embodiment provides a method of treating an interval of a subterranean formation having a permeability that varies. The method comprises contacting the interval with a water-soluble hydrophobically modified polymer capable of selectively reducing the effective permeability of the interval to water without a comparable reduction of the effective permeability of the interval to hydrocarbons. The hydrophobically modified polymer modifies the interval to have a more uniform permeability without substantially preventing the flow of fluids through the interval. The method further comprises introducing a treatment fluid into the interval. The more uniform permeability of the interval allows for a more uniform treatment of the interval by the treatment fluid than would be allowed without treatment of the interval with the hydrophobically modified polymer.

    摘要: Fracturing, frac-pack, and gravel packing procedures are provided which utilize a treating composition comprising a carrier fluid and a particulate blend. The particulate blend consists essentially of a large particulate material and a small particulate material. The large particulate material consists essentially of particles smaller than about 4 mesh but not smaller than about 40 mesh. The small particulate material consists essentially of particles smaller than about 16 mesh but not smaller than about 100 mesh. The small particulate material is present in the particulate blend in an amount in the range of from about 5% to about 60% by weight based on the amount of the large particulate material present in the particulate blend. A prepacked screening device including a large particulate/small particulate blend of the type just described is also provided.

    摘要: A method of preparing high density particulate slurries is provided whereby slurries containing in excess of 23 pounds of particulate per gallon of fluid can be introduced into a subterranean formation. In accordance with the method, a viscosified pad fluid is introduced into a wellbore to create a filter cake in a desired zone within a subterranean formation. The high density slurry then is introduced into the formation to substantially fill any annular space present without significant settling. This permits the coating of the entire exterior surface of highly deviated casing exposed within a wellbore.
