Patent ·
OSTI ID:7096643

A method for sealing a permeable subterranean formation, particularly adjacent to a wellbore, is disclosed. Briefly, the method comprises: (a) adding a liquid polymerizable material (e.g. furfuryl alcohol) to the wellbore at the site adjacent to the permeable subterranean formation, (b) adding an acidic catalyst to the wellbore at the site defined in (a), (c) allowing polymerization to occur both in the well-bore and in the adjacent subterranean formation, and (d) removing the polymerized material from the wellbore. 6 claims, 4 figures.
