Abstract

See full text

A viscoelastic composition containing an effective amount of at least one cationic carbohydrate ether having one or more cationic fragments and one or more carbohydrate fragments connected through one or more linker fragments for controlling the viscoelasticity of the composition, wherein at least some carbohydrate fragments are connected to the linker fragments through ether bonds. The viscoelastic composition of the present technology may be used to alter fluid rheology and impart both viscous and elastic properties to the treated fluids. Applications of the viscoelastic composition of the present technology include, but are not limited to, oil field fluids such as, for example, well bore treatment fluids.
