  • In-situ foam generation for water shutoff
    Patent number: 11945996
    Abstract: A system and method for water shutoff, including providing a treatment fluid including a polymer and a nitrogen-generating compound through a wellbore into a water zone in a subterranean formation, generating nitrogen gas in the water zone by a reaction of the nitrogen-generating compound, generating foam from the nitrogen gas and the treatment fluid in the water zone to give foamed polymer in the water zone, and sealing the water zone with the foamed polymer.
    Type: Grant
    Filed: January 5, 2022
    Date of Patent: April 2, 2024
    Assignee: Saudi Arabian Oil Company
    Inventors: Ayman Raja Al-Nakhli, Wajdi Mohammed Buhaezah
  • In-situ foamed gel for lost circulation
    Patent number: 11787993
    Abstract: A system and method for treating lost circulation, including providing a treatment fluid including a polymer and a nitrogen-generating compound through a wellbore into a lost circulation zone in a subterranean formation, generating nitrogen gas in the lost circulation zone by a reaction of the nitrogen-generating compound, generating foam from the nitrogen gas and the treatment fluid in the lost circulation zone to give foamed polymer in the lost circulation zone, and plugging the lost circulation zone with the foamed polymer.

  • Energized fracturing fluid by generation of nitrogen gas
    Patent number: 11578259
    Abstract: A system and method of hydraulic fracturing, including providing a fracturing fluid having a nitrite-containing compound through a wellbore into a subterranean formation to hydraulically fracture the subterranean formation, thereby forming fractures in the subterranean formation. The technique includes generating nitrogen gas (and thus foam) in the fractures via the nitrite-containing compound, and in which generating the nitrogen gas facilitates flowback.
