Claims8
A composition, comprising:
- a shape memory polymer proppant composed entirely of a shape memory polymer material, wherein the proppant has an activated state and a programmed state, wherein in the programmed state of the proppant has a programmed state diameter, wherein in the activated state of the proppant has an activated state diameter, wherein the activated state diameter is equal to or greater than the programmed state diameter, wherein the proppant in the programmed state will convert to the proppant in the activated state when an activation condition is applied to the proppant in the programmed state, wherein the activation condition is selected from the group consisting of:
- an activation temperature, a moisture, a light, a pH, a magnetic field, an ultrasonic current, electricity current, and a combination thereof.
