Low Salinity Water Flooding (LSWF)

 Low Salinity Water Flooding (LSWF), which injects brine with a lower salt content, is one of the emerging EOR technologies. This technology has recently attracted attention due to its reduced environmental impact and lower cost compared to other EOR technologies (e.g. chemical flooding, etc.). The potential benefits of LSWF were first proposed in the early 1960s and became more commonly researched in the 1990s. While many positive results have been reported, the mechanisms that contribute to oil recovery by this method are still under further investigation. JOGMEC currently is focusing on determining LSWF’s potential for practical implementation and evaluating its applicability for deployment, through both laboratory experiments (“core and fluid analysis” and “core flooding”) and numerical simulations. In 2015, JOGMEC started a joint study on LSWF with Vietnam Petroleum Institute (VPI). In this study, JOGMEC and VPI are jointly evaluating the applicability of LSWF to a particular oil field of interest, in Vietnam.
