Low Salinity Water Flooding (LSWF) is an improved water flooding technique that enhances the oil recovery with a relatively cheaper cost. Such technique becomes vital as the oil price keeps falling significantly at the global scale. Although plenty of research work has been devoted towards LSWF in conventional sandstone reservoirs, the research on LSWF in fractured reservoirs is still at its beginning stage and a lot needs to be explored in this direction. In this context, an attempt has been made in order to deduce the conceptual model that will describe the mechanism of LSWF in a fractured aquifer using dual-porosity approach. Unlike the conventional sandstone reservoirs, which are based on single-continuum concept, the fractured reservoirs are associated with a multi-continuum based concept and hence, the mechanism of LSWF still becomes complex. Two different types of conceptual models have been proposed in the work. The mechanism of LSWF technique takes place only within the low-permeable rock-matrix, while the high-permeable fracture just acts as a conduit and carries the released oil towards the production well in Model 1. However, in Model 2, the mechanism of LSWF technique takes place both within the low-permeable rock-matrix as well as on walls of the high-permeable fracture. In this context, a detailed list of possible queries that may arise during the experimental/field investigations of LSWF in a fractured reservoir has been discussed in detail. This work is expected to provide further insights for carrying out the LSWF in a complex fractured reservoir. © 2020. All Rights Reserved.
