Abstract
Propping compositions comprising: a hardenable, liquid external phase comprising an element selected from the group consisting of: a cement, a cement foam, a polymer, a resin, an aluminum, a flowable carrier fluid, and any combination thereof; and an internal phase that is either gas or liquid and that is immiscible with the external phase; wherein the internal phase exits the propping composition as the hardenable external phase hardens, leaving behind an hardened, interconnected porous network. Some propping compositions may require contact with a treatment for removal from the hardenable external phase and the treatment for removal may comprise at least one material selected from the group consisting of: an acid, a base, a chelant, an oxidizer, a solvent, and any combination thereof.

A propping composition comprising:
- a hardenable, liquid external phase comprising an element selected from the group consisting of:
- a cement, a cement foam, a polymer, a resin, an aluminum, a flowable carrier fluid, and any combination thereof;
- and
- an internal phase that is either gas or liquid and that is immiscible with the external phase;
- wherein the internal phase exits the propping composition as the hardenable external phase hardens, leaving behind an hardened, interconnected porous network.
A propping composition comprising:
- a hardenable, liquid external phase comprising an element selected from the group consisting of:
- a cement, a cement foam, a polymer, a resin, an aluminum, a flowable carrier fluid, and any combination thereof;
- and
- an internal phase that is liquid and that is immiscible with the external phase wherein the internal phase requires contact with a treatment for removal from the hardenable external phase;
- wherein the internal phase exits the propping composition as the hardenable external phase hardens, leaving behind an hardened, interconnected porous network.
