    摘要： 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.

    摘要： An apparatus for determining a carbon sequestration characteristic of a geological material includes a sample holder within an inner chamber and a pressure pump configured to apply a confining pressure to the inner chamber, a first pressure gauge and a second pressure gauge configured to measure a fluid pressure at the fluid inlet and a fluid pressure at the fluid outlet, respectively, and a carbon dioxide pump configured to inject carbon dioxide into the inner chamber via the fluid inlet. The apparatus further includes a separator for separating a volume of carbon dioxide from fluid flowing from the fluid outlet, and a return line configured to return at least a portion of the volume of carbon dioxide separated by the separator to the fluid inlet.
