International Classification:
E21B 33/138
US Classification:
166292, 166300
Abstract:
A method of limiting or preventing fluid flow through a portion of a subterranean formation comprises the steps of: (a) forming a treatment fluid comprising: (i) a water-swellable, water-insoluble elastomer in the form of discrete particles, wherein the particles of the water-swellable, water-insoluble elastomer have a characteristic of being capable of sticking together to form an agglomeration when exposed to water; and (ii) a carrier fluid for the water-swellable, water-insoluble elastomer; and (b) injecting the treatment fluid through a well into the subterranean formation to deposit the discrete particles of the water-swellable, water-insoluble elastomer in the subterranean formation.

International Classification:
E21B 43/267
US Classification:
1662801, 166278, 166279, 166300
Abstract:
A method is provided for treating at least a portion of a subterranean formation. The method includes the steps of: (a) introducing a treatment fluid into the subterranean formation, wherein the treatment fluid comprises a proppant and a swellable particulate; (b) swelling the swellable particulate, wherein the step of swelling is performed prior to, during, or after the step of introducing the treatment fluid; and (c) degrading the swellable particulate in the subterranean formation, wherein the step of degrading is performed after the steps of introducing and swelling.

Assignee:
Halliburton Energy Services, Inc. - Duncan OK
International Classification:
E21B 33/13
US Classification:
166292, 1663051
Abstract:
Methods for treating an interval of a subterranean formation having a permeability that varies include identifying the interval to be treated; introducing a relative-permeability modifier into the interval, wherein the relative-permeability modifier modifies the interval to have a more uniform effective permeability to water, and wherein the relative-permeability modifier comprises a water-soluble polymer; and introducing a sealant into the interval, wherein the more uniform effective permeability of the interval allows for a more uniform treatment of the interval by the sealant than would be allowed without treatment of the interval with the relative-permeability modifier.

Abstract:
According to one embodiment, a treatment fluid for a well includes: (a) a water-soluble polymer, wherein the water-soluble polymer comprises a polymer of at least one non-acidic ethylenically unsaturated polar monomer; (b) an organic crosslinker comprising amine groups, wherein the organic crosslinker is capable of crosslinking the water-soluble polymer; (c) a Lewis acid; and (d) water; wherein the treatment fluid is a crosslinkable polymer composition. According to another embodiment, a method for blocking the permeability of a portion of a subterranean formation penetrated by a wellbore is provided, the method including the steps of: (a) selecting the portion of the subterranean formation to be treated; (b) selecting estimated treatment conditions, wherein the estimated treatment conditions comprise temperature over a treatment time; (c) forming a treatment fluid that is a crosslinkable polymer composition comprising: (i) a water-soluble polymer, wherein the water-soluble polymer comprises a polymer of at least one non-acidic ethylenically unsaturated polar monomer; (ii) an organic crosslinker comprising amine groups, wherein the organic crosslinker is capable of crosslinking the water-soluble polymer; (iii) a Lewis acid; and (iv) water; (d) selecting the water-soluble polymer, the crosslinker, the Lewis acid, and the water, and the proportions thereof, such that the gelation time of the treatment fluid is at least 1 hour when tested under the estimated treatment conditions; and (e) injecting the treatment fluid through the wellbore into the portion of the subterranean formation.

Halliburton Energy Services, Inc. - Duncan OK
International Classification:
E21B 33/13
US Classification:
166292, 1663051
Abstract:
Methods comprising identifying an interval of a subterranean formation to be treated, the interval comprising multiple portions, each portion having a different effective permeability; introducing a relative-permeability modifier into the interval; and, introducing a sealant into the interval. The relative-permeability modifier modifies the interval to have a more uniform effective permeability to water-based fluids. The relative-permeability modifier comprises a water-soluble polymer. The more uniform effective permeability of the interval allows for a more uniform treatment of the interval by the sealant than would be allowed without treatment of the interval with the relative-permeability modifier.
Weak Organic Acid As Gelation Retarder For Crosslinkable Polymer Compositions
A treatment fluid for a well includes: (a) a water-soluble polymer, wherein the water-soluble polymer comprises a polymer of at least one non-acidic ethylenically unsaturated polar monomer; (b) an organic crosslinker comprising amine groups, wherein the organic crosslinker is capable of crosslinking the water-soluble polymer; (c) a weak organic acid; and (d) water; wherein the treatment fluid is a crosslinkable polymer composition.
