| titleOfInvention | BRONSTED BASE SALT AND BRONSTED ACID AS A GELIFICATION RETARDER FOR RETIMABLE POLYMER COMPOSITIONS. |
| 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 ethylenically unsaturated non-acidic polar monomer; (b) an organic crosslinker comprising amine groups, wherein the organic crosslinker is capable of crosslinking the water soluble polymer; (c) a salt of a weak Bronsted base and a Bronsted acid; and (d) water; wherein the treatment fluid is a crosslinkable polymer composition. According to another embodiment, a method is provided to block the permeability of a portion of an underground formation penetrated by a drillhole, the method that includes the steps of: (a) selecting the portion of the underground formation to be treated; (b) select the 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 ethylenically unsaturated non-acidic polar monomer; (ii ) an organic crosslinker comprising amine groups, wherein the organic crosslinker is capable of crosslinking the water soluble polymer; (iii) a salt of a weak Bronsted base and a Bronsted acid; and (iv) water; (d) select the water soluble polymer, the crosslinker, the salt of a weak Bronsted base and a Bronsted 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 drilling well into the underground formation portion. |
