Abstract

Methods are presented to induce a screenout during a subterranean formation fracturing or combined fracturing and gravel packing treatment having a viscoelastic surfactant-based carrier fluid by laying down a filter cake at least a portion of which is a base-soluble material, injecting proppant slurry, and causing hydrolysis and dissolution of the solid base-soluble material by adding base so that leak-off increases, the concentration of proppant in the fracture increases, and the proppant screens out. A method of gravel packing with a viscoelastic surfactant-based carrier fluid by laying down a filter cake at least a portion of which is a base-soluble material, injecting gravel, and causing hydrolysis and dissolution of the solid base-soluble material by adding base. Methods of slowing or accelerating the hydrolysis and dissolution are given, and addition of bridging-promoting materials is included.

Claims (10)

1. A method of causing a screenout in a subterranean formation stimulation treatment comprising injecting a slurry of a proppant in a viscoelastic surfactant based carrier fluid above fracturing pressure to create one or more fractures, comprising:
a) forming a filter cake comprising a solid base-soluble material, and b) degrading the solid base-soluble material with a solid base-soluble material degradation agent while injecting a slurry of a proppant in a carrier fluid.
2. A method of causing a screenout in a subterranean formation stimulation treatment comprising injecting a slurry of a proppant in a viscoelastic surfactant based carrier fluid above fracturing pressure to create one or more fractures, comprising the steps of:
a) injecting a pad fluid comprising a solid base-soluble material that forms a filter cake, b) injecting one or more first slurry stages comprising a proppant in a carrier fluid; and c) degrading the filter cake with a filter cake degradation agent while injecting one or more second slurry stages comprising a proppant in a carrier fluid.
3. A method of gravel packing a subterranean formation, comprising injecting a slurry of a gravel in a viscoelastic surfactant based carrier fluid, comprising:
a) forming a filter cake comprising a solid base-soluble material, and b) degrading the filter cake with a filter cake degradation agent while injecting a slurry of a gravel in a carrier fluid.
4. The method of any of the preceding claims wherein the solid base-soluble material degradation agent is a base.
5. The method of Claim 4 wherein the base is selected from alkali metal alkoxides, alkali metal carbonates, alkali metal bicarbonates, alkali metal hydroxides, ammonium hydroxide, or mixtures thereof.
6. The method of any of the preceding claims wherein the filter cake comprises a fluid loss additive selected from water-soluble polymers, crosslinked water-soluble polymers, asbestos, starch, calcium carbonate, mica, plastic particles, solid wax, wax-polymer particles, insoluble salts, slowly soluble salts, or mixtures thereof, provided that at least one component can be broken or dissolved.
7. The method of any of the preceding claims wherein the solid base-soluble material is selected from lactide, glycolide, polylactic acid, polyglycolic acid, copolymers of polylactic acid and polyglycolic acid, copolymers of glycolic acid with other hydroxy-, carboxylic acid-, or hydroxycarboxylic acid-containing moieties, copolymers of lactic acid with other hydroxy-, carboxylic acid-, or hydroxycarboxylic acid-containing moieties, or mixtures thereof.
8. The method of any of the preceding claims wherein the solid base-soluble material is mixed with a solid acid-reactive material selected from magnesium hydroxide, magnesium carbonate, magnesium calcium carbonate, calcium carbonate, aluminum hydroxide, calcium oxalate, calcium phosphate, aluminum metaphosphate, sodium zinc potassium polyphosphate glass, or sodium calcium magnesium polyphosphate glass.
9. The method of any of the preceding claims wherein one or more of the injected fluids comprises a bridging-promoting material.
