Investigation of in situ gel for water shut-off /reduction in multi-zoned production wells
Application of straddle packer or conventional mechanical isolations are difficult to perform for multi-zoned production wells. These methods are also not suitable for zones having high water cut and significant oil production.
This paper presents different water shutoff solutions and provides some main results of evaluation of in situ gel for relative permeability reduction, which is considered an appropriate method to reduce water production and water cut for multilayer oil fields with complicated geological structure like Hai Su Trang and Te Giac Trang.
