Cosurfactant-Enhanced Alkaline/Polymer Floods for Improving Recovery in a Fractured Sandstone Reservoir

  • M. R. Islam

Abstract

This paper presents a new recovery technique for improving waterflood performance in a fractured sandstone reservoir. The presence of fractures leads to very early water breakthrough and makes it difficult to drain the matrix of the fractured reservoir. Consequently, these fractured reservoirs are left with considerable amounts of unproduced oil. An effective technique for plugging the fractures and simultaneous treatment of the matrix to produce oil will lead to great improvement in oil recovery from fractured reservoirs. One such technique is presented in this paper.
