摘要:
Stabilizing a subterranean formation containing water-sensitive clays with methods including introducing a leading-edge fluid comprising a first base fluid and a first clay stabilizer solution wherein the first clay stabilizer is present in the first base fluid at a first concentration; and then introducing a treatment fluid comprising a second base fluid and a second clay stabilizer solution wherein the second clay stabilizer is present in the second base fluid at a second concentration, wherein the first concentration of clay stabilizer solution is higher than the second concentration of clay stabilizer solution.
