Claims14
A method for temporary plugging in a subterranean formation comprising:
- providing a composition comprising a cementitious material, water, and a swellable glass additive;
- introducing the composition into a subterranean formation;
- allowing the composition to set into a single solid mass;
- and
- allowing the swellable glass additive to swell, such that the swelling of the swellable glass additive fractures the solid mass into two or more masses.
The method of 10 wherein the organic solvent is allowed to contact the solid mass for a period of about 24 hours or longer.
