Publication number: 20180346800Abstract: 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.Type: ApplicationFiled: May 30, 2018Publication date: December 6, 2018Applicant: BJ Services, LLCInventors: Diankui Fu, Angel F.
