Abstract:
Methods and compositions for treating a subterranean formation with salt-tolerant cement slurries including treating a salt-containing subterranean formation having sodium salts, potassium salts, magnesium salts, calcium salts, or any combination thereof comprising: providing a salt-tolerant cement slurry comprising: a base fluid, a cementitious material, a pozzolanic material, a salt-tolerant fluid loss additive, a salt additive, and optionally, an elastomer, a weight additive, a fluid loss intensifier, a strengthening agent, a dispersant, or any combination thereof, introducing the salt-tolerant cement slurry into the subterranean formation; and allowing the salt-tolerant cement slurry to set.

Claim (Index 11):
A salt-tolerant cement slurry comprising:\n dry components, wherein the dry components comprise:\n a cementitious material, wherein the cementitious material is present in a range of about 5% to about 60% w/w of the dry components, \n a pozzolanic material, wherein the pozzolanic material is present in a range of about 0.001% to about 60% w/w of the dry components, \n an elastomer, wherein the elastomer is present in a range of about 0.001% to about 20% w/w of the dry components, \n a weight additive, wherein the weight additive is present in a range of about 0.001% to about 30% w/w of the dry components, \n a strengthening agent, wherein the strengthening agent is present in a range of about 0.001% to about 40% w/w of the dry components, \n a dispersant, wherein the dispersant is present in a range of about 0.001% to about 4% w/w of the dry components, \n a salt-tolerant fluid loss additive, wherein the salt-tolerant fluid loss additive is an amphoteric copolymer and wherein the salt-tolerant fluid loss additive is present in a range of about 0.001% to about 3% w/w of the dry components, \n a fluid loss intensifier, wherein the fluid loss intensifier is present in a range of about 0.001% w/w to about 2%, and \n a salt additive, wherein the salt additive is present in the range of about 15% to about 40% w/w; and \n a base fluid, wherein the base fluid is present in an amount to balance the dry components.
