摘要
Embodiments herein include a method comprising providing a self-sealing cement slurry comprising an aqueous base fluid, a cementitious material, and a vulcanized oil and water swellable particulate composite, wherein the vulcanized oil and water swellable particulate composite comprises an elastomer, a crosslinked water swellable superabsorbent polymer, and a hydrophobically modified water-soluble polymer; introducing the self-sealing cement slurry into a subterranean formation; and allowing the self-sealing cement slurry to set, wherein the vulcanized oil and water swellable particulate composite is capable of swelling in the presence of a non-aqueous fluid and an aqueous fluid to reduce the permeability of fluid flowpaths in the set self-sealing cement slurry upon loss of structural integrity.
