Abstract
The performance of new microgels specifically designed for water shutoff and conformance control was investigated extensively at laboratory scale. These microgels are preformed, stable, fully water soluble, size controlled with a narrow size distribution, and nontoxic. They reduce water permeability by forming adsorbed layers sufficiently soft to be easily collapsed by oil/water capillary pressure, so that oil permeability is not affected significantly. Because the manufacturing process of these new microgels makes it possible to vary chemical composition, size, and crosslink density, they can be designed to meet the requirements of a given field application.
