Paper presented at the SPE Improved Oil Recovery Conference, April 22–25, 2024
Paper Number: SPE-218171-MS
... Abstract One of the significant issues in producing heavy oil is that the higher inherent in situ oil viscosities lead to poor displacement during a waterflooding operation. Polymer flooding has been shown to be beneficial to improve overall recoveries with a modest decrease in mobility ratio...
