Screening and evaluation of modified starches as water shutoff agents in fractures and in matrix flow configurations Conference Paper uri icon

abstract

  • Chemically and/or physically modified starch polymer samples were subjected to preliminary screenings involving rheological tests, sedimentation tests, and stability tests at varying pH and temperature. The samples passing these tests were selected for core flow testing. The functionality of a new generation of modified starches was evaluated for profile control applications in matrix and in fracture flow configurations. A new type of fractured core cell was designed and constructed for testing the polymer samples. The device allows the aperture of the fracture to be set independently during the experiment.
