Abstract
A method and apparatus for sealing well bores is disclosed. The apparatus comprises plates which initially have a width smaller than the diameter of the well bore to be sealed or plugged. The plates are fabricated from a mineral substance which has the property of swelling into an expanded state upon contact with and absorption of a liquid. The apparatus further comprises means for placing the plate within the well bore. Among the mineral substances which may be utilized for forming the plate are members of the group of clay minerals known as smectites, including sodium montmorillonite, calcium montmorillonite, sodium bentonite, and calcium bentonite. A method sealing a well bore with the apparatus is disclosed.
