چکیده

The low salinity waterflooding (LSW) technique has become one of the mostimportant research topics in the oil industry because of its possible advantagesfor improving oil recovery compared to conventional seawater injection.Researchers have proposed several mechanisms for the LSW process in theliterature; however, there is no consensus on a single main mechanism for thelow salinity effect on oil recovery. Because of the latter, there are few modelsfor LSW and especially for carbonates due to their heterogeneity andcomplexity. In this paper, we present a comprehensive review on low salinitywater injection for both sandstones and carbonates. This review includesdescriptions of laboratory works, underlying mechanisms and field-scale pilotsin sandstones and carbonates. List of recommendations and conclusions areprovided based on this vast literature review. This paper can be used as a guidefor starting or implementing lab-scale and field-scale projects on low salinitywater injections.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
