... Abstract Improving sweep efficiency from heterogenous reservoirs necessitates the injection of gel treatment and/or polymer solution to lower the degree of heterogeneity and to lower the mobility ratio, respectively. In this study, three gel systems were compared with partially hydrolyzed...

....( Jarrell 2002 ) Gel application is considered the most aggressive type of conformance control. Conformance control approach employs gel treatments to act as a blocking agents reducing channeling through fractures or high-permeability zones of oil reservoir without significantly damaging hydrocarbon...

... Abstract Because polymers and gels can reduce permeability to water much more than that to oil, an unfavorable displacement (high mobility ratio) usually occurs in oil zones when wells are returned to production after bull-headed gel treatments. Since oil displacement through gel is unfavorable...

... Abstract Results of polymer gel treatments in injection wells, suggest worldwide that there is a positive correlation between larger gel volumes and resulting incremental oil production in offset producing wells 1 – 5 . However, gel placement procedures, particularly in matrix (unfractured...
