| titleOfInvention | Clay Control Additive For Wellbore Fluids |
| abstract | A clay control additive for wellbore fluids comprises a blended starch polymer solution comprising a quarternary amine-functionalized starch polymer. The polymer is preferably cationized to a degree of substitution of at least 0.30. The starches may be synthetic or blended from natural amylose cationic starches. In an embodiment, a further additive comprises cactus mucilage obtained from the Opuntia genus, which may be combined with the starch polymer in a 1 to 95% solution. In another embodiment, both the starch and the mucilage may be further combined with conventional additives (e.g., choline chloride) to further enhance the clay control properties. |
