  • Publication number: 20180346800
    Abstract: Sealers are used to selectively divert flow through liner openings during stimulation operations. The sealers comprise an aggregate of dissolvable particles that will allow the sealer to dissolve more quickly once the stimulation operation is finished. The aggregate preferably comprises a distribution of different particle sizes. Larger particles will provide the primary bridge across the opening, with smaller sizes filling gaps between the larger particles and allowing the aggregate to more effectively plug the opening.

  • Publication number: 20180209260
    Abstract: Compositions include (1) aggregating compositions capable of forming deformable partial or complete coatings on formation surfaces, formation particle surfaces, downhole fluid solid surfaces, and/or proppant surfaces, where the coatings increase aggregation and/or agglomeration propensities of the particles and surfaces to form particles clusters or pillars having deformable coatings, and (2) aggregation stabilizing and/or strengthening compositions capable of altering properties of the coated clusters or pillars to form consolidated, stabilized, and/or strengthened clusters or pillars. Methods for stabilizing aggregated particle clusters or pillars include (1) treating the particles with an aggregating composition to form aggregated clusters or pillars and (2) treating the aggregated particle clusters or pillars with a stabilizing or strengthening composition to form consolidated, stabilized, and/or strengthened clusters or pillars.
