Reducing permeability of highly permeable zones in subterranean formations |
| abstract |
High permeability zones in a subterranean formation are reduced in permeability by the time-delayed gelation of water soluble polymers in such formation with alkoxy amine esters of boric acid which slowly hydrolyze. Boric acid resulting from the hydrolysis converts to the borate ion which crosslinks the polymers to form gels. |
