Shale hydration inhibitors and subterranean treatment fluids containing them |
| abstract |
Method for inhibiting the swelling and/or the dispersion of shales during the treatment of subterranean shale formations comprising the steps of: a) providing a subterranean treatment fluid comprising from 0.001 to 10% by weight of a polyester obtained by reacting a dicarboxylic acid having from 2 to 8 carbon atoms with a specific alkoxylated diamine; b) introducing said treatment fluid into a wellbore at a pressure sufficient to treat the subterranean shale formations. |
