Abstract
Certain emulsions and masses produced using those emulsions exhibiting improved permeability and stability, and methods of preparation and use in subterranean operations, are provided. In one embodiment, the emulsions comprise: a plurality of inorganic particulates; an internal aqueous phase in an amount of at least about 50% by volume of the emulsion; and a continuous organic phase comprising at least one polymerizable monomer and at least one surface active agent in an amount of up to about 10% by volume of the organic phase.
Claims20
An emulsion comprising:
- a plurality of inorganic particulates;
- an internal aqueous phase in an amount of at least about 50% by volume of the emulsion;
- and
- a continuous organic phase comprising at least one polymerizable monomer and at least one surface active agent in an amount of up to about 10% by volume of the organic phase.
A porous polymer barrier that resides in at least a portion of a subterranean formation and forms a fluid-permeable barrier between an unconsolidated portion of the subterranean formation and at least a portion of a well bore adjacent to the unconsolidated portion of the subterreanean formation, the barrier having been formed from a water-in-oil emulsion stabilized with inorganic particles, the emulsion comprising:
- a plurality of inorganic particulates;
- an internal aqueous phase in an amount of at least about 50% by volume of the emulsion;
- and
- a continuous organic phase comprising at least one polymerizable monomer and at least one surface active agent in an amount of up to about 10% by volume of the organic phase.
An open-celled, porous polymer mass located in a subterranean formation formed from a water-in-oil emulsion stabilized with inorganic particles, the mass having at least one of the following properties:
- a gas permeability greater than about 500 millidarcies;
- or
- a plurality of pore throats connecting a plurality of pores spaces therein, the pore throats having an average diameter of at least about 1 p.m.
