  • DIVERTING MATERIALS FOR WELL STIMULATION
    Publication number: 20230416600
    Abstract: Compositions containing a diverting material, and related methods and systems for diverting a fluid from a high permeability zone in an underground formation to a low permeability zone in the underground formation. The diverter material contains a polyurethane and a second polymer. The compositions, methods and systems may be used to achieve more homogeneous stimulation during a well stimulation treatment.
