What is claimed is:
1. A method of stabilizing swellable clays in a subterranean formation comprising:
providing a treatment fluid comprising a biopolymer based cationic surfactant that includes a quaternary ammonium compound having an alkyl polyglucoside backbone and amino alcohol side chains; andintroducing the treatment fluid into the subterranean formation.
The present invention relates generally to methods of stabilizing a subterranean formation. In particular, the present invention relates to methods of stabilizing swellable clays in the formation and methods of reducing the formation of sludge in the formation using a biopolymer based cationic surfactant.
