Networked polymeric gels and use of such polymeric gels in hydrocarbon recovery |
| abstract |
A composition includes water having a salinity of at least 1 ppt, at least one hydrophilic polymer containing primary (-NH2) and/or secondary (-NHR) amine groups and at least one saccharide containing a reducible function. A method of changing the permeability of a subterranean formation includes the step of injecting into a subterranean formation a composition comprising water, at least one hydrophilic polymer containing at least two groups which are independently the same or different a primary amine group or a secondary amine group and at least one saccharide containing a reducible function. |
