Claims11
A modified cement material, comprising:
- a cement slurry material including a shape memory polymer additive, wherein the shape memory polymer is in a programmed state;
- and
- wherein the shape memory polymer is an ionomer.
A modified cement material, comprising:
- a cement slurry material including a shape memory polymer additive, wherein the shape memory polymer is in an activated state, and wherein the shape memory polymer is about 0.01-10 weight percent of the cement slurry material or modified cement material;
- and
- wherein the shape memory polymer is an ionomer.
A modified cement material, comprising:
- a cured cement material including a shape memory polymer additive, wherein the shape memory polymer is in an activated state;
- and
- wherein the shape memory polymer is an ionomer.
A method of stopping or reducing shrinkage in cement, comprising:
- disposing a shape memory polymer additive into cement slurry to form a modified cement slurry material, wherein the shape memory polymer is an ionomer in a programed state;
- exposing the modified cement slurry material to an activation temperature, thereby causing the shape memory polymer additive to expand;
- and
- exposing the modified cement slurry material to a formation temperature to set into a modified cement material, wherein the activation temperature of the shape memory polymer is less than the formation temperature of the cement.
