  • Method of Diversion and Zonal Isolation in a Subterranean Formation Using a Biodegradable Polymer
    Publication number: 20170081585
    Abstract: Various methods for redirecting a well treatment fluid to targeted zones of a subterranean formation within a reservoir and diverting the fluid away from high permeability or undamaged zones of the formation by temporarily blocking the high permeability zones are provided. A well treatment fluid can be diverted from a high permeability or undamaged zone of a formation within a reservoir having a high bottomhole temperature by introducing into the reservoir a biodegradable polymer that has excellent heat resistance.
