Title

Application and Development of Chemical-Based Conformance Control Treatments in China Oil Fields

Abstract

With the growing need of producing oil and gas resources, the life extension of mature hydrocarbon reservoirs has become a real challenge for the coming decades. China represents the largest user of chemical-based conformance control treatments and a series of technologies have been successfully developed and deployed in recent years. A review covers the current status of the application and development of chemical-based conformance control treatments in China; types and development history of conformance control treatments; technology information for conformance control; theories and applications of some promising combination technologies of chemical based conformance treatment and other EOR/IOR processes, including the combination technology of surfactant and water shutoff, profile control and mini-type surfactant flooding, acid treatment and profile control treatment; representative agents (high molecular weight of polymer and their crosslinking systems, like hydroacrylimide); and problems and challenges that mature Chinese water flooded oilfields are facing.
