Laboratory study of polymer gel behavior Conference Paper uri icon

abstract

  • Studies were conducted on the permeability reducing characteristics of polyacrylamide/chromium gels and on the reformability of Xanthan gum/chromium gels that have been degraded by shear. Results of the polyacrylamide/chromium gel study have shown that weak gels reduce sandpack permeabilities a small amount; strong gels completely plug sandpacks when the pressure differential is below the yield stress of the gel. The regelation study of Xanthan/chromium gels has shown that gels that have been sheared take longer to reform than to gel initially and that the original gel strength was often not recovered after shearing.
