Types of gels used for conformance improvement - PetroWiki

This article describes the chemical make-up and application of the types of gels most commonly used in conformance improvement. Oilfield conformance improvement gels come in a wide range of forms and chemistries.[1] Table 1 provides an overview of various conformance improvement gels. CC/AP gels have an exceptionally robust gel chemistry and are highly insensitive to oilfield and reservoir interferences and environments. They are also applicable over an exceptionally broad pH range.[2] As a result, these gels, when properly formulated, are applicable to the acidic conditions associated with CO2 flooding for which most earlier oilfield polymer gels did not function well.
