Consolidated material to equalize fluid flow into a wellbore
First Claim
1. A method comprising:
- flowing an unconsolidated material and a consolidation fluid into a wellbore formed in a hydrocarbon-bearing subterranean zone;
binding the unconsolidated material with the consolidation fluid to form a pack;
after binding the unconsolidated material with the consolidation fluid, dissolving at least a portion of the pack with a postflush fluid to increase permeability of the pack; and
after dissolving at least a portion of the pack with the postflush fluid, equalizing a flow of fluids through the pack.

Abstract
Methods for equalizing flow into a wellbore using consolidated material are described. An unconsolidated material and a consolidation fluid are flowed into a wellbore formed in a hydrocarbon-bearing subterranean zone, and a permeability of the subterranean zone to flow fluid through the subterranean zone into the wellbore is non-uniform across an axial length of the wellbore. The unconsolidated material and the consolidation fluid are contacted across at least an axial segment of an inner surface of the wellbore, and the unconsolidated material is bound with the consolidated fluid to form a pack, in which the pack has a permeability that is more uniform than the permeability of the subterranean zone. A flow of fluids from the axial segment of the subterranean zone into the wellbore is controlled through the pack.

8. A method for completing a well, the method comprising:
-
flowing an unconsolidated material into a wellbore formed in a hydrocarbon-bearing subterranean zone; flowing a consolidation fluid into the wellbore; at least partially consolidating the unconsolidated material within the wellbore using the consolidating fluid to form an at least partially consolidated material; after at least partially consolidating the unconsolidated material, dissolving at least a portion of the at least partially consolidated material to increase permeability of the at least partially consolidated material; and after dissolving the portion of the at least partially consolidated material, equalizing a flow of fluids through the at least partially consolidated material. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
