Abstract
A method of treating a subterranean formation including suspending proppant particulates in a treatment fluid, wherein the proppant particles include a coating comprising a salt-tolerant, water-swellable polymer, and the treatment fluid includes at least one fluid consisting of fresh water, salt water, seawater, brine, an aqueous salt solution, and combinations thereof; and introducing the treatment fluid containing the settling retardant proppant particulates into the subterranean formation. A composite proppant particle includes a proppant substrate and a salt tolerant polymeric layer deposited on the proppant substrate.
Claims21
A method of treating in a subterranean formation comprising:
- suspending settling retardant proppant particulates in a treatment fluid, wherein the settling retardant proppant particles include a coating comprising a salt-tolerant, water-swellable polymer, and the treatment fluid comprises at least one fluid consisting of fresh water, salt water, seawater, brine, an aqueous salt solution, and combinations thereof;
- and
- introducing the treatment fluid containing the settling retardant proppant particulates into the subterranean formation.
A method of treating in a subterranean formation comprising:
- introducing a treatment fluid containing settling retardant proppant particulates into the subterranean formation, wherein the settling retardant proppant particles include a coating comprising a salt-tolerant, water-swellable polymer, and the treatment fluid comprises at least one fluid consisting of fresh water, salt water, seawater, brine, an aqueous salt solution, and combinations thereof.
